I read a post where someone suggested putting shims under traction wheels of a 4-8-2 to help with pulling power - mine really needs the help and if anyone could give more info on the process and were to get the shims it would really be appreciated!!
I didn't shim the traction wheels on my 4-8-2 , I just glued some lead weight to the inside of the cab roof . Now it pulls 9 heavyweight passenger cars with no slipping.
Red,
There are no commercially made shims for this specific purpose.
Use the thinnest shims you can to make it work properly.
I simply cut out a couple of pieces of bond paper, wiped off all oil in the
area, and glued the paper in with Super-Glue.
Make sure the paper pieces aren't too large and that you don't have
any glue spill-over.
Hope this helps,
Dick
If you did not figure it out already, the shim goes in the bottom (when the loco is upside down) of the rectangular notch in the frame for the axel bearings.
