Thank's for the info,I will give the Moto Tool a try.
I have taken a dremel with the cutoff disc and lightly touch the flanges with the engine running, touching flat side on, not the cutter edge. Works with the pilot and trailing wheels, the spin turns the wheels.
just lots of patience.
An article years ago in MR takes a metal cutting working tool and makes an NMRA shaped flange cut in it and the wheel is turned and cut with your usual Unimate lathe tool or similar.
I'm sure this has been addressed before,but what is the best way to reduce the flange size on older Rivarossi Cab Forwards,or are there replacement wheels available ? Thank you for your help,Riley.
