We have used the nylon spring-loaded ones from McMaster and it is kind of clunky and hard to incorporate into the chassis.

Can you tell me which nylon round stock you used? I don't need a picture but others may benefit from one.

Thanks

I believe it was McMaster part # 8664K15

Do a mcmaster search for oil-filled nylon rods I believe we used either the 1 1/2in or the 2 in rod.

Do you know if the oil-filled nylon is better than the oil-filled UHMWPE, part number 5243T23? The reason I ask is that the chain guides you are using are made from UHMWPE not nylon.

When playing with the chain, the UHMWPE seemed to be a little more slippery. We used the nylon because we already had it, if I was ordering material for the tensioners i would go for the UHMWPE.

McMaster part number 8664K15 is enough to last for a few years

i have to say i do like the pulltrusion shape that easily makes what would've taken multiple pieces of other materials to make. And it would've most likely ended up heavier.

looks like a great drive base, how much did you lower the center wheel?

Center wheel is lowered 1/8"

We used the nylon because we had it on hand--Either should work well.
