    So I had some hubs made at emachineshop.com for a pretty reasonable price (under 1000 for two) because with the design of my frame there was no way that I could use a stock rear, and I had some wacky ideas for the front. They did a good job, I just had two complaints.

    1) Some wires got crossed and they anodized it grey, instead of just giving me a vibratory finish.
    2) they tapped the holes deeper than they should have, resulting in exposed threads, which i didn't like. This isn't necessarily their fault, I called out a 3/4 thread depth on the print, but they may have tapped 'til they got 3/4 thread depth on a taper tap. I don't fault them too hard for it.

    Stripping off the anodizing shouldn't be a big deal, but the the threads needed something done, so I threw it in the rotary table and used a ball mill to clean it up.





    Next I polished up the rotor and sprocket carriers for the rear. Polishing aluminum is actually a little tougher than stainless, in that it scratches much easier. Even a blue Surface Conditioning pad will leave scratches too deep to get out with a sisal wheel. There are some micro scratches here that the picture REALLY brings out, but they're almost imperceptible IRL. I'm going to use a product called glisten PC on these, which is a clear coat specially formulated for polished aluminum.





    I've decided I am going to run a full polish and very little paint [BUT NO CHROME] on most of the parts on this bike, so I couldn't use old crusty motor parts, however, I want to keep the character of 75 year old parts, so I decided to keep the beat up parts as-is and just polish the parts to a shine.

    Here's some work on the cam cover:



    Surface conditioning belt:



    More of that:



    Then wet sand, cut, buff:

    Are there any small parts that need polishing that aren't delicate like aluminum? The reason I ask is that there are small affordable machines you can buy to polish die cast stuff. My dad used to reload rifle/pistol cartridges. He had a tumbler to polish the cases. Tumblers can be bought at any gun shop, or Gander, Cabela's etc. They are meant to polish brass. But it is possible to change the media inside of them.

    Yeah, there are SO many options to tumble (mass finish) stuff, but the problem is it's not selective, so if you put something in there with critical machined faces, they can become off.

    But to answer your question, yes, a lot of these parts may be able to be tumbled, I just don't have the equipment.

    LOL @ Vibratory finish and holes deeper.

    I was in a grown up training session for a few days so maybe I'm just extra immature today?

    Good looking progress

    I have been working on this a lot, just not posting a lot of updates. Here are some pics and not a lot of text.

    Designed a fork:







    Got castings:



    Some pics of some parts I made:



    Had to machine the castings:

























    Fucked this one up. It was late and I was tired and added .100 to .750 and got .760. Can see the hole is offset to the right:



    Had to weld



    Mill flat:



    Bore:



    Better:



    More parts:



    Made these from solid bar:



    Polished/smoothed:



    More polished parts. About 14 hours of polishing time for these two parts.












    Wheel layout. Note assymetrical front hub. (will be half radial laced, half 4 cross.)

    What method are you going to use to secure the tubes to the lugs?

    Welded.

    I originally was going to silver solder or braze, but I think I should just weld it and be done w/ it.

    I cannot imagine how much heat would have to be applied to get solder/brazing rod to flow with lugs that big.

    The only one that would matter would be the last part I posted, the lug is .75 X 1.25. I would pin that one first. The other lugs are only .75 X .75 and are loaded in compression only.

    This one needs a little more work. But it's entirely bolt on so I'm not sweating it at the moment.
