on a home made wrapper? It has no bearing, but otherwise looks good.

Thanks!

Bearings aren't a necessity. The wheels on the Renzett Master Rod Lathe don't have bearings in them. They are nylon or delrin of some sort and simply turn on the smooth shoulder of a chrome plated screw. We don't turn rods that fast or under so much pressure than a bearing is absolutely necessary.

Depending on the material the wheel is made from, you may be able to run it dry or you may have to add just a touch of powdered graphite.

YES

Ed Should work fine I use wheels tat are Plastic Skate wheel conveyor parts and they work great As tom said not much RPM and no pressure. I also have all Alum wheels rolling on Stainless bolts

i dont know if this will put damper on things but the center hole on those wheels is very small. As I recall the Futaba servos have a very small shaft also one other thing i recall the shaft is shaped like a gear and so is the inside of the hole so when mounted creates an interference fit. You might want to see if there are specs available for the Futaba servos that could tell you the diameter of the shaft that in turn wil tell you the size of that center hole.

I would think putting a small bushing inside would be better than just running on the plastic since this wheel wasnt really ment to run freely on a shaft.

I think you will have problems without modifications to the wheel. First, the hole in the middle is toothed to interlock with the splined shaft coming out of the servo. Second, the hole in the end of the gear (where the attachment screw goes) is much smaller in diameter than the side that goes towards the servo which would necessitate you drilling it out. For $4 I would think there are much better alternatives.

Just my 2¢
