Long crank pins

[nachoman]

Can you take a photo of exactly what you need? I am failing to understind this setup. I have an HOn3 MDC 2-8-0 (outside frame) that had worn crank pins. I solved this by drilling out the old ones, glueing in pieces of brass tubing, tapping the inside of the tubing for an 00-90 screw, and then attatching with a hex head screw. The tubing extends through the drive rod and is slightly longer than the rod - that way I can tighten the screw all the way down and the rod has the perfect amount of clearance.
