Hallo, I have some old locomotives (mainly from LIMA) with old style "pizza cutter" flanges that do not fit my Code 83 rails. Unfortunately the older LIMA locomotives can not have their wheels replaced as there is a plastic gear glued to the inner side as in the Picture 14 in this webpage (3rd from top) http://www.rivarossi-memory.it/LIMA/Tecnica/Lima_Motori/Motore_H0_02_G/Lima_Motore_G.htm The locomotives to be worked on are 2 or 3. Is there any way I can scrape off that 1/10" that does not imply buying a milling machine? Is there anyone of the small model workshops that may offer this service? Or where can I get both replacement wheels and gears (unfortunately i think in this case gears have to be made to measure) without spending a fortune? Very difficult questions, but thanks to anyone that can help.
