note to Jay at DMC
The frame arrived today with wheel and another box which must be appendages. I haven't even unwrapped them yet
but at least now I can start work.
Just out of curiosity, does shipping parts to Hawaii get really expensive?
Not to bad if you use the postal service.

One of the things I an having a problem with is the part that slides into the frame. the point at which that tube is welded to the frame has a decreased inside diameter.
This is most likely due to shrinkage after welding. The part only slides in as far as the welded area. Any recommendations?

Hello Jim. when you work with welded parts, shrinking on spots is normal. In general the diameter is not that much affected. Sometimes it is less then the paint thickness.
I would use some Prussian blue or easier to get hand on is some permanent marker. Spread/mark the internal part stick it in as far as you get wiggle and twist so the external part will get marked. Look with a bright flash light and work only on those marked spots or with a triangle scraper, or with a die grinder or Honer (flexhone or brake cylinder hone). Or if all the sticking is not too much, then simply get some FINE valve grinding compound, ...(I love Clover brand) and after some body exercise the parts should slide fine.
By the way you can use the course valve grinding paste as anti-slipping compound too. Once you clamp parts they should be locked better then on pure paint.
Good luck with your project.
Yesterday I took off my Ural sidecar for the first time... assembled dry as usual. Wiggle gaps all over the bike. It was time to do something before damage would show up.

It should fit, we run a ream down the inside after we do the welding, chances are the powder coat is just a bit thicker then normal.

Okay thanks, I may have to use a cylinder hone, it's pretty tight.
