A couple of rivets have failed on the valve gear on my Williams USRA 4-6-2. I am wondering how to repair it, and where I can get parts--rivets and tiny washers? You'll note from the photo that the eccentric crank is soldered on, so I'm hoping it's possible to perform the repair without removing the valve gear from the loco.

Check out the Precision Scale O Scale Steam Locomotive catalog. You can view it on line. Pages are in alphabetical order. They have a whole page showing rivets for valve gear with measurements.
Also, you should not have to disassemble the valve gear to do the job, what with being able to turn the flywheel to move things around. YouTube has videos here and there about this, for suggestions. The scale doesn't really matter.
Just be patient and gentle, especially before you are used to it. A little snug is OK, as they will wear in.
The 700E-54 and 55 rivets would be a good match for repairing the valve gear. Available from www.ttender.com
