OSSA Super Pioneer

If in doubt, or it doesn't seem to fit elsewhere - put it here.

Nice find. You don't see those around too often. My last Curnutts was on a Husky 500xc.

I see I mentioned this on the Benelli mini thread. So I’ll put it here where it belongs (for the 2 people that read it).

I got a newer ‘conical’ front brake hub and backing plate. That will be for the longer travel Betor forks I picked up NOS. They have a different backing plate holding system, so I’m just making an entire setup so I can leave the stock stuff alone.

I didn’t like the inner bearing spacer, sort of rusty. So I made one from aluminum 6061 rod I had.
Somehow rather than leaving it long and facing to fit- I managed to make it short. Oh well, could have welded it and cut I suppose, but I just made another. Good practice for me anyway.
After doing that, I realized the length of the stock one seemed a little long- Appeared it would have too much pressure on center of bearing if the bearing outer races were fully seated.
So I made a couple measuring ‘slugs’ and I can verify the spacer will be the right length. Plus I made one end of one with a guide, so I can use it to more easily install bearings.

Fun stuff, but the rod is a little big for my little machine, so had to use a live center so I could cut it.

Now to remember what those slugs were for so you don't make another one :P
A vapor hone is still on my wish list. Finish is so much nicer than the soda blast finish.

Yes, I should label or stamp them.
Although if I just put them in with all my other bearing drivers, they should be pretty quick to find.

I may be getting a larger vapor honer, one of the reasons I spent too much on the new air compressor. The one I have is fine with the air my old one put out-but the larger one probably would want more. The small one works pretty darn well, but just can’t fit larger stuff in there and of course takes a little more time.

Let me know if you decide to part with the small honer.

I certainly will.

Edit:
I sent you some email John re: vaporhoner
