Re: Thunderhex and Thunderhex Bearings

I have used shrinking to fit thunderhex into bearings before. I used liquid nitrogen(-320 F) to do it, but dry ice(-109 F) should do just fine and a lot of grocery stores carry it.

Aluminum shrinks/expands ~0.001"-0.0015" per inch per 100 degrees F, which you can get about 1 thou shrink with dry ice or about 2 with liquid nitrogen.
