I'm betting the first one was done with a ball end end mill on a rotary table in a mill, or a CNC mill. I bet Newman did his by hand with his air file!

Haha, nailed it, although the dynafile did factor strongly into the final shaping!

The second one, though. Is that hand work?

Made a shift knob from a marble and some 12GA 316.

Also made these vband exhaust spigots. I'm hoping I can weld or braze them onto the head, but I need to do some more research about that.

Scrambling trying to get the engine together and working on 3 things at once. Seat at at upholsterer, tins are at painters. Focusing on trying to get the engine built so that I can get the exhaust and foot controls built.

Here are some things that happened in the past week:

Made some special stud covers to close off the holes in the CE reg I modded.



Started working on some floorboard pedal thingers:





Always a shame grinding off (semi) pretty welds





I got this cast exhaust piece that I designed. It goes underneath the trans and will have vbands on both ends.



I welded my vband flanges that I made a few posts back to the head. Super high stress job. Took about 7 hours. Preheat, weld 3/8", back in the oven, repeat, then slow cool down cycle. Welds looked good and no cracks. Then I powdercoated them wrinkle black which may not be everyone's thing, but I like it. Valve guides and rocker shafts are one-off... I have a plan coming together there. Rocker shafts are out getting carburized now.



Last night I bead blasted and prepped the case for glyptal. Me and my buddy Dave at BA enterprises put new Jim's main races in the case and honed them. Cover bearings reamed, lots of threads fixed, etc. Hoping to put the bottom end together this weekend. I think I have all the parts.

I personally love wrinkle black, my horseshoe is done in it, looks so good finished.

Flanges may be a god send, the old style ones are such a pain in the ass, my back pipe will literally not stay tight!

Lovely welding too man!

Why is that little section on the left case near the breather channel masked off from the glyptal?

Thanks for continuing to post up progress!

It's the scraper plate. Old timer who is helping me with my motor says it needs to be masked off, so i masked it off. He explained why but I was doing it at like 2 am and can't recall.

I thought it would look great on your bike as soon as I saw it!
