RE: schumo king tiger wheel bearings ?
I just bought a drill press to do some work on my HL Jagdpanther, and I also had some clearance problems with the output shafts and my custom ball-bearing mod on my new Mato Rev2 gears. I stuck the output shafts in my drill press and took some sandpaper to them. Bearings slide on with no binding now. If it's only the brass output shafts that are binding, this is a good solution, I wouldn't do it on hardened metal shafts such as chrome steel, it's those shafts where there is binding.
