Oh. My. God. That’s wonderful.

Frankly; I’d be terrified to ride it around here. Too many idiot cagers to [potentially] take you out.

That looks beautiful. Love the color contrast of the bolt heads, unless my eyes are getting old and it’s the same color?

They’re heat treated 17-4ph (180ksi), so yes. They’re sort of a brown color.

Lots of work here. 30 hours over 3 days into this part, excluding design time.

Scrapped the old steering neck. Got this new casting. Has a hole to help fixture it.

The hole worked!

Looking pretty good after hitting it with 240 for a few hours. Not shown: several more hours of 400 and 600 grit

Lots of dust and belts and sandpaper:

Rough polish with a sisal wheel and black rouge:

Then it was back to the mill to machine the hole in the neck a bit and then back to the buffer… nice and shiny

Then to finish it off, a pair of uncirculated 1940 walking liberty half dollars. My bike is officially worth 1 dollar. Some minor scratches I have to polish out after assembly.

Bump.

Got some of the frame done. 316L SS construction. Coins in the neck are 1940 walking liberties. (motor is a 1940 knuck motor). Seems like my rear external drive setup is going to work. Not fully welded yet. Still need to make a bunch of frame parts including neck gusset, rear motor mount, rear trans mount. Will go back in the jig for that. Motor is rotated back 6 degrees for more vertical downtubes. All oil lines run inside frame. Tires are on backwards because I’m dumb. Everything is custom, really. Front hub is assymetric and laced half 4 cross, half radial.

This was the only picture I took of a weld. It came out kind of wavy and it’s in the most visible area. If it bugs me too much I’ll go over it again…

Can we get a better shot of the downtube where you have what look like spindles about a foot from the lug?

I don’t have any completed close shots at the moment, but here are the pieces before I welded them in, and when the frame was just in the jig held together with nothing but zip ties. These pieces were done on a manual lathe. Rough tooled with lathe tooling then shaped to final with a file.

Also, I just finished up this neck gusset tube/upper motor mount parts on my lunch break. You can see the oil crossover tube on the front section.

In case you were wondering how it was done. Multiple pieces, then threaded together and welded.
