I don't seem to be able to source teflon locally (Canberra), but a guy at one of the local shops suggested that UHMWPE (ultra high mol. wt. polyethylene) was similar and actually had better characteristics in terms of not sticking when you move it. I'm just wondering whether anyone here has used it and can vouch for it. I also recall seeing a post somewhere that suggested using one of those white plastic chopping boards instead. My Googling suggests that good chef's chopping blocks might be UHMWPE, but I don't think the the Woolies version would be.

My intended use is slightly different to how it would be used in a Dob's bearings. I'm trying to devise a sort of thrust bearing to dampen a bit of wobble in one of my alternative EQ platform ideas. I'm wondering whether a couple of circular pieces of teflon sandwiched between 2 bits of wood with a bolt through the middle to control the friction would work...
