After far too long of a battle, I finally succeeded. I didn't realize it, but the front axle used a proprietary thread pitch and size, somewhere between 7/16-24 and 11mm-ish. I ordered several different sizes and thread pitches, and nothing fit. So I replaced that axle with a standard 3/8"-24, but my new problem was that the bearing race on the hub was larger than any bicycle bearing cone I owned. I tell you, getting exact manufacturer specs for stuff like bearing races and cones is a freaking nightmare. But I finally cobbled together the parts and got the front sorted. While I was at it, I swapped the fork with the wrong brake mount tab with one on the correct side. Yes, I said it, the brake was backwards and I was an idiot. But everything is shiny now, and both wheels are built and trued

Finally got started on the frame. It's going to be mostly 1" tubing. Used my 1" rigid conduit bender to make a 55° bend, then cut it extra long and threw it up on the frame jig. It already looks spicy!

This is gonna be kool~! I like how your tire width and rim width are almost the same. You pulled a hot rod look on a skinny tire build. :nerd:

RaT oN~!
 
Working on the frame today.

I wanted a few interesting details on it, so rather than just capping the end of the tubing, I sliced it at an angle to make some spikey bits, then capped them and blended the weld for a seamless appearance

Got a bit more work on the rear section done today.

I don't have a fancy shmancey Tig rig, but I do have skills with flame welding. I'm pretty rusty, but it looks decent enough.

Got the rear axle spacing figured out with help from the oxygen tank cap.

Still have to work on the dishing of the rear rim, it's off by about 1/2" on this current setup
 
Added the seat brace.

Originally rolled it to match the radius of the wheel, but I liked it better at an odd angle.

I wanted it to flow better with the spike on the bottom, so I fired up the torch and gave her a tug.

Still working on the design for the dropouts and the rest of the rear end, and I also decided that it needs some kind of a tank
 
I'm really enjoying this build. I love fabrication and scratch builds. Looking good!
Thank you. This one has been gnawing at the back of my head for quite a while. Feels good to finally get it out where I can beat it with a hammer (where necessary, lol)
