thanks for the link on that shop! i'm going to get some of my cnc router bits cryogen'd.. they are usually only good for 100-120 boards before the finish starts to chip. eager to see how much longer they last after getting treated.


and for the OP - i had my 4.77 gears cryogen'd .. well actually i had them thermal cycled like a 24 hour process, but cryogen is still better than nothing. the place that did it is in florida though. i recommend doing the cryogen.
