I dug my old tubing bender out today and bent up the frame. The plans show the neck made out of the same tubing as the frame. I made a change and decided to machine the neck out of a piece of stainless steel bar to accept precision bearings. This will prevent the steering from being sloppy. After bending and cutting all of the tubing and machining the neck, it was time to get on the lay-out table and tack up the frame. You can get a good size comparison of the frame in this photo.

I was ready to finish weld the frame but I was nervous so I watched my old "How to Weld" VHS tape 3 times and took some notes. Then I sharpened up a .040 piece of 2% Thoriated tungsten and locked it into my TIG torch. I had to bring over an extra bottle of Argon so that I could put about 2psi of Argon into the tubes while welding. Once I had everything set-up, I sat down, hit the pedal and let her burn. After welding I polished out all of the welds. Can you pronounce sssslllloooowwww. The neck area was the hardest place to polish because the tubes and neck are close together. Now I have to decide how high to mount the axle to get the desired ground clearance. Then fit the engine so that I can fab and weld in the motor mounting plate. Ah, 1 step at a time.

I started on the front forks today. The first thing was to put a piece of scrap stainless in the CNC machine. An hour later this is what came out of the machine. Now I just need to prepolish it before welding in the fork tubes.

I finally had time to weld up the front forks today and mock up a roller. Now I need to buff out the welds on the front end and then start machining the wheel hubs.

x90 how is the tom thumb bike coming along? I finished polishing all of the welds on the front forks and I am trying to work on the fuel tank but I am tight for time right now. I will post some photos as soon as I make more progress.

I picked up the seat from my buddy in Parma and attached it to the frame. Next, the stainless steel fuel tank was fabricated, polished, and mounted, so now I need to machine a stainless steel billet fuel tank cap.
