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



Hi,
Are you talking about the terminal isolation blocks where the heavy wires connect? 

Maybe something here would work???

This isn't good. The two square spacers on my E15 motor have crumbled and harold has not been able to source replacements. I figured this time would eventually come and it's time to start figuring out replacements.

First thought I tried was rubber hose and electrical tape. Seems like a good idea but the first time the motor loads up the heat will melt the rubber/plastic and make a mess. Need a high temp solution.

Anyone got any other ideas? Personally I may try making a mold and building a pair of cubes of JB Weld, then drilling the centers. JB can handle muffler temperatures (500f) so it should be able to handle a motor. Any other ideas?
