Re: (ET) First parts to go NLA--Motor spacers



If we are talking about the terminal insulators I would recommend starting with a purchased material that has some toughness and strength.  I think it needs some temperature resistance but nothing exotic.  I don't think the motor housing should really get above 210 F, so something with intermittent use to 250 F should be ok.  I have some that need replacing on a E12 motor so I will be interested to here what you decide to do and how it works.

McMaster-Carr has a wide selection of high temp insulating materials, in
various sizes and shapes. Something could be machined from an
appropriate material.
