Thanks everyone.

How about instead of 5, you give us some details on that flap polishing disc?

This is an incredible build, I love the castings.

. I meant it. Yours if you want it.

Do you mean this one?



All it is is a sheet and a half of cloth backed sandpaper cut into 1/8s, then just put over the top of a small buffing wheel. I can take no credit, see this video: https://www.instagram.com/p/_zrcXauiej/ I think he is a chopcult member actually.

I did find that using about 1.5 sheets vs 1 sheet allows you more overlap. Secondly, when it's wearing down, loosen the nut about one turn then start the buffer, the sandpaper flies out a bit before the nut self tightens and it gives you more sandpaper to work with. It's CRITICAL that you use cloth backed sandpaper as well.


I got the motor mount welded in which was the last thing I had to do in the jig so I was able to pull it out tonight. I've gotta knock that lower neck cup out of there unfortunately. I rushed it in a few weeks ago and the stop tab attached to the cup is twisted. I can't get a good piece of it with a punch so I think I'm going to have to weld a plat across the bottom of it and wail it out.

Thanks, that's what I meant.

Again great build, I love the castings.

This is some next level craftsmanship. You are a master. I cannot wait to see what's next

That is stunning.

Bolt both pieces together and now you have a forming die:



Soaked it in water for a bit so it would start on fire. Then filled the tube with sand and packed it tight, taped it off.

***If you try this, make sure your sand is baked dry. Even if it SEEMS dry, it's not and it can explode. Bake it for a few hours.***

Next I added some heat to the area I needed the bend to occur and bent that shit up. If I had to guess I'd say the wood die would last between 5 and 10 bends. More if you soak it longer and between each.



Checked the part to my 1:1 print, looks good a little off but:



Nope it's basically perfect:



Made a second one:



Right on. Then I sanded them with 120 grit. (Polish coming soon, but wanted to test fit-up)

Coming together!





Then finally got it welded together. Excuse all the fingerprints. I swear the polishing is nearly perfect.

It is full 316L SS. Uses friction dampers on the front of the lower link, which also has stroke limiters. The hardware is all custom made 17-4PH SS. The only part I didn't make was the spring (the acorn nut shown on the stem will be replaced with something I make)
And here are the finished pics:












Once the fork was done it was time to move on to the frame:


Axle plates. These are almost totally hidden (more on that later) so I didn’t sweat the polishing too hard.




Got some more wax castings done:



Then started the arduous task of polishing them. These pictures are “in progress pictures” I actually purchased and polished them before I had even started on the fork, and I learned a lot in that time. I re-polished them, but I don’t have any good pictures.

This motor mount is desined in such a way that I don’t need a squish pipe to run exhaust between the motor mount and the cam case:

I think you have proven yourself worthy enough for invitation to any build-off......... Hell, you deserve your on TV show. None of the other shows hold a candle to what I have seen in this thread.
