simple paint roller trick

Over the course of this build, I think I may have saved hundreds of dollars simply spinning out my paint roller cores and loosening them up for the next session.  As long as you remember to pull the roller off when the epoxy is still uncured, I've found that if you let the roller handle and core cure, all you have to do is chuck them into something that will give them a good spin ( enough to sort of wear the previously used epoxy away from the spindle) This loosens up the roller enough to reuse it indefinitely........every few dollars helps.   Nice to have a little coffee money after spending a thousand more dollars for another batch of epoxy.
