Hi again, I really don't know what I'm doing but that is part of the fun.

I am going to try and build a body for it that should look like a vintage race car, I need to get some plywood to build the frame and then cover it with aluminum sheet. The one concern I have is how heavy it will end up being.

I have a Grubee GT2B 48cc that I need to reassemble to power it and a Sick Bike Parts expansion chamber to give it some extra HP. I have rebalanced the flywheels and hopefully this motor will be able to push it along at a reasonable speed.

Here are some build pictures for you to look at.

Cheers,
Dave.

Here a some pictures of my friend Mike helping me notch the ends of the tubes.

I used to drive Agitators (concrete trucks) for a labor hire company, which is how I met Mike (He's a good guy!)

I went and bought a metal hole saw to notch the ends of the tubes. The first hole saw I bought I had to take back because all the teeth wore off, oops!

It turns out that the hole saw when drilling steel needs to be spun at a maximum of 275 rpm. The new hole saw I bought came with instructions with the cutting speeds.

My cheap drill press is not able to be slowed down to the correct speed so I had to ask Mike if I could use his drill press.

Cheers,
Dave.

Dave, That looks like a velo limo. Seating for six. :)
A first rate start on the project and I see the assistant engineer is casting a critical eye on it all. I found out myself that the hole saw works at a very slow rate of speed.

Looking forward to seeing what you do for the body.

The skin for the car, does it have to be metal? A lot of early cars used doped fabric stretched over a frame, like a plane, and that worked well enough to survive until today and the homebuilders.

Hi to everyone following my build,

I mounted the coil today and soldered the wires for the magneto and worked on the exhaust as well, I had to cut it up as I wanted it down low, the previous bike it was on I had it going up and beside the head.

I am really happy with the look of the exhaust.

I have some more pictures, one is where the sitting position will be, also one of a body shell I really like and am using as guide, also one of the exhaust fitted to the bike.

Cheers,
Dave.

Hi to everyone following my build.

I rebuilt the rear coaster brake wheel and added the rag joint, I used my own bolts and still managed to strip one that is how tight I like to assemble the bolts.

I also used loose ball bearings instead of the raced bearings because I can get more ball bearings in to support the axle, but it does make it a lot harder to assemble the coaster brake hub. I also used automotive teflon grease.

After the first time I tried to assembled a coaster brake wheel, I did not get it right, bugger! I found some good videos on YouTube, the coaster brake wheel must be assembled in a certain order.

The raced bearings are 2 x 11 ball bearings and 1 x 9 ball bearings, by using loose ball bearings I can get 15 ball bearings in place of the raced bearings 11 and 11 ball bearings in place of the raced bearings 9.

Here are some more pictures, the one of the sprocket shows how well it goes onto a 36 spoke coaster brake hub. I did surface grind the dust shield to get it to fit because of the thickness of the sprocket.

Someone with good eyes will notice that the brake shoes are actually back to front.

Cheers,
Dave.

Hi again,

The postie was nice enough to finally bring some parts I have been waiting for, I bought some 7/8" and 1" nickle plated plugs from the U.S. also a vintage Raleigh seat post bolt also from the U.S.

The 7/8 plug, fills the hole where the head stem went and the 1" plug fills the hole where the seat post went.

Here are some more pictures.

Cheers,
Dave.
