Any POM/Polyoxymethylene/Acetal/Delrin® experiences?

Is there anyone here who have experimented/experiences with POM/Polyoxymethylene/Acetal/Delrin® ?

A loved child has many names, well known for its fine properties for various mechanical applications AND being cheap as peas. POM would be an excellent candidate for a "rack & piniony" X & Y, even Z I suppose alá this. That one could fit into a T-slot aluminium extrusion. Should speed things up a bit no? tongue sticking out smiley

I don't know if it is possible to use POM as filament(?), but in any case it should be possible to go the other way around by "casting it" in random mouldmaterial that can take it. Pellets should be easy to find and cheap!

At first I was thinking pewter but that would be to tempt things I suppose...
Aluminium would work very well as a mold, it seems to be the most costeffective/readily available method for this application?

By "casting it", I suppose I mean more of very academic "squishy something after a mould thing"-term since POM's bonding properties make bonding problematic...

Thoughts/suggestions on this matter?

Howto make a acetal leadscrew easily and cheap, aught to be "better" than any m8 nut if one can get the fit just right. I guess this also could be applied to making some dito bushings.

Anyone actually tried POM yet?

I have found a source of 3mm rod (though sadly only in 3m lengths so far) and want to have a go.

Anything I should bear in mind or be careful of? Any danger of fumes etc?

Delrin is the best plastic for machining, drilling and cutting,but even cutting it will give off toxic fumes, and you certainly do not want to melt it without some sort of ventilation.

Not sure it could be extruded, as it really does not melt in a nice way like abs

gsport, did you have any success with the Acetal/Delrin?

I have plenty Delrin in rod and blocks and a Lathe, mill, cnc mill... if anyone needs any help or has any ideas.
