@JohnActon posted:Turning plastic wheels on a lathe. Might be time well spent. What about turning some metal wheels down and make a plastic tire about 1/8" thick. Don't press, epoxy it on (hoop stress). Something I started doing on Weaver chain drives since the sprockets are so prone to splitting is to drill out the plastic parts so they were not such a tight force fit but still snug on the shaft then epoxy them in place. Roughing up the inside of the hole and the spot on the shaft where they ride. A set of numbered drill bits from 1~80 is invaluable for opening up the holes a couple of thousands. An unmounted drill chuck that goes from 0 ~ 1/4" so you can turn the bits by hand is also useful. Another trick I sometime use when drilling soft plastic like Delrin is to loosen the belt on my drill press and turn the chuck by hand. j
That’s what I’m considering at this point. I picked up a few Lionel flangeless metal wheels that I’ll have to open the I.D. a little bit on each wheel. Thank you for the info!
