Archive for the ‘Factory Five’ Tag
It’s been a few weeks since I posted an update. Some people have been asking for some news, so here we go. . .
I am preparing the chassis so I can install the engine and transmission. This means that I have to finish the firewall, which means prepping and painting the foot boxes and routing and mounting the brake and fuel lines.
I decided to finish the engine bay with silver Rust-Oleum high temperature BBQ paint. This is a change from my thoughts on powder coating and appliance epoxy. . . The appliance epoxy has an upper temperature limit of 200 degrees F, and I think engine bay heat is higher than an oven. The BBQ paint is good for 1200 degrees F or something like that. Depending on how the engine bay looks, I may strip everything off and re-finish with powder coat later. But for now, the silver BBQ paint looks OK. The nice weather last week allowed me to do some rattle-can spraying outside.
I permanently mounted my first aluminum panel – the driver’s side foot box front. I am using Permatex Ultra Black number 2105 silicone adhesive. This is what Kirkham Motors uses for their builds, so I will use what they use. It can be used as an adhesive as well as a gasket, so this extends its usefulness around the shop.

Above right is a close-up of the BBQ paint finish on one of the pedal box panels. Looks OK. There is a slight texture to the finish. The color is actually silver, the blue-ish tint is probably from sunlight diffracting from somewhere.
Above left, a “dry fit” of the driver side foot box front panel. You can see the cookie sheet heat shields in place. Above right, using the panel as a pattern to cut the insulation mat – just place the panel onto the backing side of the mat, press down and then cut with shears or a knife. Final trimming is done with a utility knife.
Cool-It heat and sound insulation is applied to the interior side of the foot box panel. The “bubbles” you see are from the riv-nuts and screws poking out from the other side. On the right, I wanted to make sure the adhesive stuck properly at the top of the panel, so I used some clamps to squeeze evenly. My good friend Norm Abram always says, “You can never have too many clamps.”
The Accelerator Cable and Pedal
I mounted the accelerator cable as well as the Russ Thompson gas pedal, sold by Breeze Automotive. The instructions are different from what is being supplied by Factory Five Racing now. (I am getting used to this. . . )
The picture above shows some of the gas pedal mounting parts that come with the Complete Kit. The Thompson / Breeze pedal instructions say something about a “green plastic barbed clip” at the end of the throttle cable. This green thing is no longer what comes with the kit. Instead, there is a little square “plug” that is too big to fit into the pedal mount.
Rather than cutting off the ball-end at the throttle cable or drill a bigger hole in the mount, I decided to carefully cut some of the plastic from the center barb so it would fit snugly into the mounting hole – not much has to be shaved off, it is something like a sixteenth of an inch or so. Then I made a slit in the square plastic thing as shown so the cable could slip in with the ball intact.
As you can see above, I added a fender washer (painted black) to the throttle cable mounting point, this is just for looks.
This is Irritating
For some reason, this bothered me today, but then I realized not many tubes of caulk gun goop come with caps. Anyway, I used a pen cap to close the tube. I hope this works, I only needed a few beads for this build session.
Some Great Looking Door Panels on Order!
I ordered a set of leather door panels from Levy Racing earlier this week. They look like this:
Not much Coupe time this weekend. The rear brake adapter plates and spacers from Factory Five Racing finally showed up – Saturday delivery via FedEx.
Since these are raw steel, I decided to prep and paint them, using gloss black Appliance Epoxy paint. They look much nicer now.
I removed the rear spindles from the last build session and did a dry-fit to see how these get assembled. Once again, the assembly manual and the actual assembly are different. Instructions say to use some button-head Allen bolts, but there aren’t any.
Here are some pictures of the “RH” side of the assembly to see how this goes together. The adapter plates are not painted in these images.
I will bolt these components in place in the next building session.
A Color Decision
I decided to paint the engine bay white. I know this sounds scary, but after thinking about this for a while, it just makes sense. It will match the body color, it will have nice contrast against the black chassis and the engine and other components, and – I can use Appliance Epoxy, which is pretty durable and washable. I will be painting only the outside surfaces of the panels because all of the inside surfaces will be covered with Thermo-Tec Cool-It sound and heat insulation mat.
I got tired of fiddling with the IRS so I did something different this weekend. Here is a picture of the E-brake ratchet handle that comes with the Complete Kit. Since the parts are plain, un-finished steel, I decided to paint it to prevent rust. The exploded view in the instructions make assembly very easy. I wish The Factory would include an exploded view for the IFS as well as the IRS – makes things go so much better. The finish is white and black appliance epoxy from Rustoleum.
Here are some pictures. . .
I am not sure if I like the location of the E-brake handle, it is on the passenger side of the transmission hump. A popular modification is to use a Pontiac Fiero unit and re-locate it closer to the driver. We’ll see if I want to change this setup. (The sharp-eyed people will notice the e-brake handle is backwards. . . . . . )
Here are some images of the air conditioner and a cardboard aided design (CAD) templates I am making. This requires some cutting of the dashboard and firewall, so I want to mock everything up before I start cutting. I have some very sturdy aluminium plates for the A/C baseplate, and some sheet aluminum for the enclosure. A CAD version will be made first, then transferred to aluminum.
Moving back to the IRS, I received some advice from the veteran builders, and so here is what I did to the lower control arm mounts. The shims (thin black steel washers) F5R supplies are slipped into place and some adjustment is done by placing shims here and there. However, it makes more sense to limit the toe and camber adjusters so that the tweaking can be as simple as possible. By “fixing” one side of the control arm, and limiting it to one adjuster for toe and one adjuster for camber, alignment is simplified and less time consuming.
Currently, this stage is to just “eyeball” the adjustments, and continue the build process. Wheel alignments – both front and rear – may be done after the wheels and tires are mounted. (Probably can be done at the “go kart” stage, when the chassis is complete and the engine, drivetrain, electrics and brakes are installed and running.)
Here are some pictures. As this step gets closer to completion, I will add more details for future reference.
Above left: The Type 65 Coupe IRS lower control arm mounts. One shim on the front side of the mount, six shims on the side toward the rear of the car. The heim joint is threaded on so that 5/8-ths of an inch of thread are showing.
Above right: Here is the trick I use to install slippery washers, shims and spacers onto things – Use a punch or some other tool to poke through the stack of parts together, thus aligning the holes of each part. Then . . .
. . . push the fastener – and the punch – through the stack of parts. Wiggling, pushing and pulling will help. Sometimes a quick-clamp can help, too.
Maker Faire 2013 Update: Application is In!
I turned in an application for Maker Faire Bay Area 2013. Our Maker name is “Not Your Grandpa’s Ham Radio 2” and we will continue the theme my team entered last year. We will have some new projects on display, and we will bring some of the more popular items from last year. Here is a look at some of our projects from last year – as well as some other interesting and amazing things I saw last year.
Above – One of the most interesting exhibits at Maker Faire 2012 — The Electric Giraffe named Russell – it is a scaled-up and enhanced version of a plastic model kit – it is 17 feet tall.

Some Body Parts, More IRS Conundrum and a New Microwave Antenna for KH6WZ
Inspired by a post on the Factory Five Racing forum and the dry and sunny weather this weekend, I decided to paint some of my body mounting parts. I am using gloss black Rust-Oleum Appliance Epoxy paint for these pieces. I have used this paint for my electronic and radio projects with good results. The paint dries very hard and is waterproof and washable, perfect for these parts.
Surface prep is easy for this paint, I scuff the surface with a 60 grit sanding disc on my random orbit sander. For the hard to reach nooks and crannies, I use a wire wheel chucked in my hand drill. Then I use liquid dish soap and water to wash off the grit and any oils. No primer is needed for this paint. Then I apply two or three light fog coats first, and then blast a thick coat for the fourth or fifth and final coat.
Here is a “before” and “after” picture of the front nose mounting hinge.
I did the same with the door hinges. Here you can see some weld splatter that will interfere with the mounting bolts, so I used a Dremel tool to grind those weld balls off.
Although many of these parts will not be seen, I do not want them to rust. Other parts will be painted in the same way, and include the door frames, the rear glass hatch hardware and the emergency brake mechanism.
Meanwhile . . .
After spending some time fiddling with the factory-supplied accelerator pedal, I decided to buy an aftermarket gas pedal instead. I ordered one of Russ Thompson’s gas pedals earlier this week from Breeze Automotive, one of the Factory Five Racing Forum supporters. I was amazed the box arrived on Thursday – that was fast!
The new gas pedal is really a machined aluminum sculpture. Pictures on this will be coming later, since I need to get the engine mounted before the gas pedal goes in.
IRS – Finished – Sort Of . . .
The IRS section is now fully “dry-fit” completed, and the bolts will be tightened to specs in the next work session. One thing that is putting this assembly step on hold are the mounting points for the lower control arms – see the gold color on the right of this picture? That is the mounting bolt and as you can see, there is a lot of empty space between the mounting ear and the thin washer (the manual calls them shims). This cannot be correct, and I need to find what is wrong here. . . .
Just after I ordered my Type 65 Coupe kit, I came across a lot of posts on the forums about the IRS shafts (CV joints) coming apart. Those messages made me worry, but when my kit was shipped, the CV axles were on back-order. I called Factory Five Racing technical support, and they assured me that the problem has been fixed.
I am happy to report that my IRS system assembly went very smoothly, after the pumpkin was in place. The CV axles slipped right into the differential, and it felt just like many posts said – you can feel it lock into place. No hammering, no drama and no R- and X-rated words necessary.
Once again, Chris comes to the rescue by posting images of the IRS knuckles and which part goes on the left side and which one goes on the right side.
Here are some additional pictures of the IRS components and system . . . . “R” is for Right side of vehicle (passenger side in the US)
Above left: The IRS upper control arm has another pair of small mounting tabs that are not mentioned in the assembly manual. No pictures are included in the manual, either. After a quick search on the Factory Five forum, I found out the smaller set of tabs point downward, and are used for quad shocks – used to minimize wheel hop during acceleration.
Give Me a Brake – Again
Now, the rear brakes are another story. Seems the Factory sent me the wrong rear brake kit. So now I have to wait for the correct parts to arrive, and then have to send the wrong parts back. . . Stay tuned for more . . .
Another Box Arrived this Week – a 10 GHz Slot Antenna
I received this nicely machined antenna for 10 GHz earlier this week. It is made by fellow SBMS member Dan, W6DFW.
Here’s a picture of this omni-directional microwave antenna. The background is the radiation pattern plotted by another SBMS member, Chuck, WA6EXV.
I am planning on using this to make my roving 10 GHz station even more portable, perhaps getting on 10 GHz FM mobile. More on this item and possible applications at station KH6WZ later.
Since the engine is in the middle of my garage, I really need to accelerate my building, or at least, get my chassis ready for engine installation.
I looked at my cookie sheet heat shields and the mounting locations filled with 8-32 riv-nuts, and thought – shoot, the riv-nuts actually have a shaft that might be used as stand-offs for the shield plates. So I checked the length, and the threaded shafts are about a quarter-inch long, enough to be used as a spacer between the firewall and the heat shield. I may add another quarter-inch in certain places, if there is room.
So I spent a few hours removing all of the riv-nuts I installed a few weeks ago. Good thing I bought several hundred from McMaster-Carr. . . .
At least I am an expert on installing and extracting riv-nuts now.
Rivet Nuts and the Rivet Nut Tool
Here are some pictures of the riv-nut tool from McMaster-Carr and how it is used. Riv-nut fasteners are very handy if you need a threaded hole installed into a blind location, or when you do not have access to the back side of a mounting surface. I will use these fasteners for hatches and compartments in the trunk area of the Type 65 Coupe.

Above left – a picture of a properly installed riv-nut, viewed from the reverse (back) side. At right, a riv-nut improperly installed, viewed from the face (front) side. This one must be removed by drilling the riv-nut out. Below left, use a twist drill slightly smaller than the mounting hole, in this case, a 1/4-inch bit is being used to drill out the riv-nut. By slightly rocking the drill, the riv-nut will break apart and, usually, just fall out of its hole.
Give Me a Brake: The Wilwood Pedal Box
The pedal box is a challenge to install with the Factory Five Racing Assembly Manual, revision 3E, July 2011 – since there are no assembly instructions for the Wilwood Complete Kit pedal box.
Fortunately, a dedicated Type 65 Coupe builder named Chris has an excellent photo album of his Coupe build, with many detailed images. Without his documentation – it would have been impossible to assemble this part of the kit. Take a look at cbergquist1’s photostream on Flickr.
Here are some pictures of my pedal box, including a trouble spot I ran into, and how I had to fix it. . . .
This is the clutch quadrant adjuster (above). This Nylok had to be ground down to fit properly. The hole in the adjuster plate is too close to the master cylinder mounting plate. A better solution would be to eliminate the Nylok altogether and thread the small plate. Then the lock nut and Allen bolt are used to make clutch travel adjustments.
Now I have to find a place to mount the master cylinder reservoir. There are some rare posts about this, but most of them are for the Factory Five Racing Roadster.
I think I will mount mine at or near the peak of the driver’s side footbox/firewall. This location should be away from too much heat, and should be in the clear for fluid bleeding, checks and re-filling. We will see. . .
The Gas Pedal
Part of the pedal box area is the accelerator pedal. Again, instructions are very skimpy on how to put this thing together. Here are some pictures of the gas pedal parts and how to dis-assemble the unit as it comes out of the box, and where it mounts onto the firewall area. Adjustments for the pedal box and accelerator pedal will happen later.
The Factory Five Racing Cruise-In at Huntington Beach is expanded to include both Pier Plaza and Main Street this year. On top of all this, a tour of the Riverside Auto Museum and an autocross event is scheduled for Sunday, April 28.
The event is free and open to the public, an entry fee is charged for Factory Five Racing car display space.

Here are some random photos from last year’s event. . . .
It has been raining off and on all week, and continued through this past weekend. This is a good thing, since I can avoid yard work, and even better – I can spend more time in the garage. However, the garage has been cold, 40 degrees F. This pretty much kills any plans for painting anything.
Since the 80 pound metal medicine ball – also known as the pumpkin, center section, differential and other names – is re-sealed and mounted, the rest of the independent rear suspension assembly is going smoothly.
Learning something from the front suspension experience, I decided to assemble all the pieces on one side of the car first, and only hand-tighten the fasteners. This will prevent time-consuming error-fixing.
There is a saying on the Factory Five Forums – it goes something like, “if there aren’t any pictures, it didn’t happen.”
So, since there aren’t any pictures of the parts I installed backwards, it didn’t happen, right?
Let’s just say the assembly manual lacks good pictures to help us understand how to orient things properly. Many of the pictures are cropped too tightly, and do not show the nearby parts to help us visualize relationships to other parts or reference points.
Here are some pictures of the driver side lower control arm and coil-over-shock being installed. . .
While mounting the lower control arms, I kept dropping a stack of small shims (they look like thin washers) needed between the chassis mounting tabs. Of course, since they are round, they roll all over and under the strangest places. I had to use a small magnet to retrieve several of them.
The magnet made me think of a great way to hold and install these small shims on the mounts. Take a look. . .
The little magnet holds the stack of shims together, and by wiggling, pushing and pulling on the suspension parts, the bolt will slide through the stack. This works great, and it makes me feel happy rather than mad while underneath the chassis.
Of course, this only works if the parts are ferrous. The aluminum spacers are another story.
The spindles, upper control arms, and CV axles are next. Stay tuned . . . .
Big day today – the 302 V8 and T5Z transmission from The Engine Factory arrived. I like how everything has little tags to tell me what this thing does and where it goes.
Click here to see a video of the engine running posted on Facebook.
On with the pictures!
My go-to car builder friend Spider Larry once again came through for me. Using a Mapp gas torch and a piece of pipe, he separated the ball joint from the top mount for the passenger side suspension. Here are some pictures from the dis-assembly and re-assembly process on the Type 65 Coupe IFS, passenger side.
Here is the correct passenger side upper control arm and ball joint assembly:
The driver side looks like this:
So you MUST ignore the manual when it says to create a “left and a right unit with the ‘solid corner’ pointing to the front of the car.”
Footbox Heat Shields
I located, dry-fit, and drilled mounting holes for the driver and passenger footbox heatshields. The material is cookie sheet steel from the local grocery store. They have a nice rolled edge and will help deflect heat from the engine bay coming into the car interior. I am using riv-nuts and spacers to mount these sheets – er – heat shields to the footboxes.
I used BBQ paint for the shields, but may decide to powder coat the engine bay sheet metal parts, including the heat shields.
But I have to decide this quickly, since the engine is scheduled to be delivered within a few days!
Here’s the driver footbox with riv-nuts installed. All aluminum panels for the engine bay will be powder coated, the others will be painted.
Air Conditioning
Here is a picture of the air conditioner unit and where it will go. It fits behind the passenger side dashboard area, where a glovebox wold normally go. I need to allow space for the ducting and the windshield wiper mechanism, which mounts in the same area. A box to house the A/C unit will have to be fabricated.
The IRS – Independent Rear Suspension
Note to builders: This procedure is quite difficult, even with a helper or two. It is highly recommended to keep small children away to protect them from hearing rated-R and -X words and phrases loudly coming from the underside of the chassis and to keep them safe from thrown objects.
Since my ham radio friend Larry was going to stop by for a visit, I decided it would be a great time to get him to help me boost the rear differential (pumpkin) into the rear suspension cage. The Factory Five Racing assembly manual calls this unit the “IRS center section.”
There are many posts on how difficult this step is. The manual says, “It installs from the bottom with the driveshaft flange pointing straight up and the axle holes lined up front to back with the chassis.”
Err. So that means the giant 70 pound, lop-sided bowling ball like thing must be pushed up sideways, 90 degrees from the way it mounts onto the frame, and then must be twisted 90 degrees in the opposite direction to drop into place. This cannot be done safely with just one person. I found out that this is actually impossible to do with two people.
After several long hours and a phone call to Spider Larry, the pumpkin still refused to go into place.
I began to think about getting a grinder and removing any offending protrusions on the differential case and chassis to make this thing fit. My ham friend Larry had to leave, but a neighbor showed up, who also happened to be a car builder. I put Phil to work right away…
We tried a different route, maybe through the X-member at the rear of the chassis could work. So we used the jack to lift the differential high enough to check. We made a few measurements. No way.
We measured again, and noticed that no matter how you turn this pumpkin, it will not fit past the rear cover mounting plates.
We decided to remove the rear cover.
After unscrewing ten Allen bolts, and giving the rear cover a light tap with a rubber mallet, the cover popped off, very much like breaking an egg. To gain another inch of clearance, we removed the two plastic dust caps from the axle holes. Verifying that the diff does NOT have to come apart to mount the rear brakes, we put it back on the jack. Modifying the instructions, we lifted it with the driveshaft flange pointing up and the axle holes at a 45 degree (not 90 degree) angle, and pumped the jack. Now it went past the offending rear mounting plates, and into place.
Of course, now the differential must be re-sealed, so we tried a dry run with the rear cover. Yes, this will work. I currently have the pumpkin suspended above the mounting location, held in place with the jack, a 2×4, and a nylon strap. I will finish mounting this beast at the next build session.
Here are lots of pictures of the wrong way to do this. A video of this procedure would be most helpful, but I am sure most builders will have enough in their hands to not have a camera operator getting in the way.
So – take my advice, save at least 6 hours and lots of non-child-approved words and thrown objects, and remove the differential rear cover before you install your IRS center section. . . .
The rear mounting tabs (with the nice “5” logo laser-cut into them) are too close – use the threaded rod-expander trick to make it fit.
By the way – anyone else missing two nuts and bolts for the pumpkin mount? My parts list is correct, and yet I am still missing two fasteners for the standard width IRS differential.
I discovered I have the wrong adapter plates for the rear disc brakes, These are for the non-IRS version of the car. Jason at The Factory is sending the correct parts to me……
The front IFS is still not right, and the responses from the forums and the directions are confirmed by Jason at Factory Five Racing. Now the difficult task involves more un-building and hoping parts are not damaged. The ball joint on the passenger side needs to be removed and the upper A-arm top plate has to be flipped over. This is a direct result of an error in the Factory Five Racing Type 65 Coupe manual (revision 3E, July 2011) on pages 60 and 61 and 63 and 64.
The manual says to install the ball joint into the upper control arm to make “a left and a right.” I did this, and now must dis-assemble one of the ball joints. A new upper control arm is more than $200, so this is a costly error if I am not able to correct this.
The correct orientation is shown on the driver’s side of the suspension. The passenger side is incorrect. This assembly is difficult to describe in words, so it is best shown with pictures.
Here is the driver side showing the upper control arm and the ball joint mount on the plate – see the wedge-shaped, “thicker” end at the apex of the triangular plate? This is correct.
This is the passenger side upper control arm. See the thicker wedge-shape on the opposite side of the apex? This is incorrect (wrong).
I dis-assembled most of the front suspension to get to this ball joint. However, the ball joint fits into the spindle via a tapered hole. . . meaning that some force must be applied to remove the ball joint stem from the spindle. I started by tapping – then pounding – with my plastic hammer, since I did not want to damage anything. No good. I changed to a scrap of oak and my ball-peen hammer and hit it hard for several minutes. Still no good. I got rid of the piece of wood and really slammed with the ball-peen hammer. Finally, the stem popped loose.
Of course, this created a mushroom on the ball joint stem, and it would not come out of the hole. I filed around the mushroom and finally separated the ball joint from the spindle. I should be able to file or grind the stem so the ball joint can be re-used.
Mushroom on the stem!
Removing the ball joint requires dis-assembly with 450 degrees F (since I used Permatex medium strength thread locker blue), a vise and a big wrench with lots of grip and torque.
I tried several times, but my vise just isn’t gripping the ball joint properly, it slips off. I need a bigger vise and a torch for this. My bench vise is too small.
Cutting the Dash
Since I could not remove the ball joint, I decided to move to another part of my project – cutting the dashboard in half. This is a popular modification that will increase access into the area between the dashboard and the firewall. This area will soon be stuffed with wiring and air conditioner ducting, so the dashboard had to be cut sooner or later.
I wondered how this was done, should I leave a “lip” on one of the sections so I can patch the panels together? Or do I just slice along the fold? What is the safest way to do this with my power jig saw?
It turned out to be easier than I thought. Here are some pictures of the cutting operation . . .
I used some duct tape and a wood scrap to hold the dashboard in place for the cut. My trusty Makita power jig saw did the trick.
I will use a piece of aluminum angle stock to mend the two sections together.
I may make a new dashboard front panel, especially since the original one has several things wrong. For example, I ordered the “modern gauges” option. There is no mention that the modern gauges are smaller than the vintage gauges. The dashboard comes with cut-outs for the larger gauges, and a triangular-shaped adapter plate for the smaller gauges. Also, the steering column hole is in the wrong place, as mentioned in a previous posting. If I knew this was going to happen, I would have ordered a plain, non-drilled dashboard – so if you are planning your order – consider asking for an un-cut, un-drilled dashboard and make custom cut-outs where you want them.
Cookie Sheet Heat Shields
A few weeks ago, I found these cookie sheets in the close-out bin at the grocery store. They have nicely rolled edges and they happen to be almost the right size for the footboxes.
The amazing part about these cookie sheets is the angle at one end – it exactly matches the angle at the back of the driver-side footbox. I will mount them with 8-32 machine screws, spacers and locking nuts. I will also add a layer of insulation (Cool-It mat) between the heat shield and the footbox panels.
I am no longer sure if I want to use the Rust-Oleum BBQ paint for my firewall and other panels. I did a paint test this weekend, and the paint is quite soft, and scratches easily.
The Battery Mounting Plate
After noticing how soft that BBQ paint is, I decided to do some more paint testing. This is the battery mounting plate. It is made of steel, and it is already starting to rust. So I decided I should paint this part and the other steel items soon.
I used Rustoleum Appliance Epoxy paint for this test. This is my standard paint for radio and electronics projects. The finish is very hard and glossy, the cured surface is washable and no primer is needed. However, it is not meant for heat, the maximum temperature is 200 degrees F.
I prep the surface by scuffing the surface with 80- or 150-grit sandpaper on a random orbit sander, followed by a dish soap and water wash. I apply the paint in three or four very light fog coats and the surface becomes slightly textured. I may go with this paint, if I can find a suitable color. The last time I looked at spray paints, this appliance finish comes in white, almond and black. Too bad it does not come in silver or gray.
Roomba Battery-Ectomy – Vacuum Cleaner Battery Replacement
After almost three or four years, the battery pack in my Roomba 530 stopped taking a full charge. I re-newed the charge cycle several times, but the Roomba would run out of charge before completing a single room. So I performed a battery-ectomy on the Roomba. It needed a good cleaning inside the chassis anyway, so this was something I needed to do. You can see the debris inside the mechanisms that are impossible to clean unless you open the case. I used my shop vac to suck out the junk inside the various nooks and crannies inside the Roomba. The new battery has a larger capacity and should provide a longer running time. This will be good, since Roomba will help increase my time in the garage and other non-house cleaning activities. . . .
Here are some pictures. . .
