Hi Mark, It's my first time machineing PVC (or any plastics realy) but sharp tooling was fine, just to run it slow or it may melt!
I made the cap a push fit (it sits 5mm over the extended wheel hub) when everything's assembled I'll put a dab of silicone on it before tapping it on, they have to stay on and be removeable for maintenance. I've currently got a 3/4" bore through my wheels, I have a stock of PTFE rod that I was going to make bushes between the fixed steel axle and the PVC wheel. Now I'm making my suspension arms and rods, I was wondering how the PVC would hold up running directly on the steel shaft? A dab of grease during assembly wouldn't hurt. My original plan was to use PTFE bushes, then if they are too soft to upgrade with bronze bushes, but if I increase my axle from 15mm to 3/4" and still get good life from the wheels I'll save time. I hope the PVC will be strong enough, I haven't profiled the inside of the wheels, so the 'inside' wheel is a solid cylinder of PVC, so if the outer 'pretty' wheel flexes the inner shouldn't. Phil. -----Original Message----- Looks nice Phyl. PVC is good stuff to machine. I used UHMW Polyetheline because its cheeper, but it is very "stringy" to cut on a lathe. Axle cap looks classey. How does the axle cap stay on? Mark -- You are currently subscribed to the "R/C Tank Combat" group.
