Remember Delrin, available at most plastics supply stores (ie. Tap
Plastics) as both rod and sheet, also maked a great tool material for
stakes, hammers, dapping punches, draw plates, etc....

Hi Susan,

Any tips for working Delrin? It seems like I need a bandsaw to cut it (which I don't have). It seems like it would file pretty easily, but how do you cut or form it?

Delrin is similar to teflon and nylon. It has good elastic properties . When cutting it on a mill or lathe, a very sharp tool is needed. If you are just cutting a rod to length then a hack saw would work well, but a bandsaw would be desirable if you are cutting flat patterns. Unless there are some tricks that I'm not aware of , Delrin does not form well. (because of the elastic properties) It comes in a variety of diameters and thickness . It is typically black in color ,but is also available in white.

Dave,

A band saw would be nice, but I don't have one (yet). I cut lengths of it with either a radial arm saw or a skill saw, and do more detalied cuts with a jig saw and or coping saw. It shapes beautifully with just about any burr. I've shaped several sinusoidal stakes (used for anticlastic raising) by using large wax burrs, and I've shaped dies, for hydralic forming, with worn out high speed burrs. The stuff is also a joy to drill, and with it I've made a number of draw plates for forming tubing, and for drawing down woven chain.
