Hi, We had quite a bit of problems when we allowed popcorn onto the shop floor, so we changed to M&M's but the problems persisted. We changed our operator feeding process over to KFC, and ever since there has been a dramatic improvement in productio

I never thought about painting our copper piping. I always thought the patina that covers the pipes adds a bit of history and class, ya know an antique-feel, to the shop. I was in a shop years ago that used PVC piping for their air. From looking a

This is an OUTSIDE corner spec or an inside corner spec? If outside, I don't see why it is a problem, but will require programming the router or making a template (if an "old school" shop.) Yes, if an inside corner, then it requires a small router
