Ricky, why not just buy them from Midas? Give them the ID and OD needed but they will probably longer than needed, but no matter.

I had bought all my 36 PU bushes (yellow ones) from a local shop at R7.05 each. No way you can make them for that price - even nylon (had made a batch but scrapped them in favour for PU) will cost you more and not to mention lathe time....

Yes, all the bushes I bought were to long and cut them back on the lathe to size and PU can be troublesome to turn.
What I did was; push a crush tube in the PU bush to just short of where you want to part off the excess - this allow for the chuck to grip properly without compressing/collapsing the bush which is a common problem with PU bush in a lathe. Set the lathe to very high speed and use parting chisel and the PU will cut easily and smoothly.

Edit: when parting off excess on lathe, the off cut side goes in the chuck with crush tube as not to damage the bush flange and part off the bush size needed with flange.

Hope this helps.
