Reply to "Sunset PRR J1 gearbox failure - NWSL gearbox now installed"

I agree with Bob.  I just finished these two USH 0-8-0s and though the photos don't show it I replaced the 4mm shaft with as long a piece as I could and got it as close to the motor as possible (in this case about 1/16").  Running low on Toyota tubing so I went to the local auto parts store and bought 3 different sized pieces of heavy wall windshield washer tubing.  Works well.   I still use other means of coupling but for these, I think the tubing was the right way to go.  I still use the KTM gearboxes but I install ball bearings on the input shaft.  Motors were Faulhabers. The last photo shows one of the new input shafts prior to installation.  The old shafts are in the top of the photo.  I do exactly the same thing with the NWSL except it's 1/8" shaft instead of 4mm.
