Subject: Machining Delrin at home

 
Hi All, 
For those contemplating machining Delrin at home (eg. in the  basement), I 
found this on a plastic vendor's website 
"Acetal plastic (sometimes known by the trade name "Delrin") is a  very hard 
plastic that is valued by machinists because it can be machined to  tolerances 
of .001". It is more slippery than UHMW Polyethylene. It can be  machined 
with any metal- or woodworking tool. (woodworking tools should take  tiny cuts 
per pass - this stuff is HARD).  
Safety Information  
DO NOT ALLOW THIS PRODUCT TO HEAT UP PAST 200F. It will outgas  ammonia, a 
toxic gas, AT LETHAL LEVELS." 
If your primary tends to get very hot, or you need a base for a  static gap, 
etc., perhaps one should consider the above in choosing materials  for an 
indoor coil. For outdoor only use, probably OK, but machine only in  
well-ventilated area only. 
Hope this is of use to someone. 
Matt D.
