I am looking for some sort of material other than wood or metal that I can turn on a lathe.  Ideally, it should be 1.25 inches in diameter, 4 inches long, able to be turned on a lathe using wood tools and capable of being drilled and tapped.  Perhaps Delrin would work.  I have never worked with it before.  Any suggestions and sources of supply would be appreciated.

Thanks

Tim

Acetal (Delrin) or UHMWPE (Ultra High Molecular Weight Polyethylene) will do the job, both can be drilled and tapped but you would need to use a very small lathe tool, especially for the acetal.... hasten slowly !!!

Can you find someone with a metal lathe???

Amazon is actually pretty useful these days for little pieces, but there's a company called www.plastiblocks.com who do some nice bundles of ABS rod

Any one using lathe for metal work he has also Acetal (Delrin) Rod for samples and testing.

Rods are sold in fixed length, you better ask for a favor (sample rod purchase) from a small factory or a shop producer of metal parts.

 

Woodwork lathe this is not accurate enough for fine work.

Thanks everyone. I found a guy with a small metal lathe who will do the job just to be helpful. I will get him some delrin to turn.
