730LP, you ask,, Quote:--� Has anyone used a air needle scaler to remnove paint and rust on the frame and castings when restoring a tractor? --Yes, I use one (actually I have 2) all the time.. I don�t use it for full frame or engine paint & rust removal.. It would work but it isn�t fast.. I like a chemical paint remover first,, then using a large rotary wire brush on a large right angle grinder to get most of the heavy stuff off.. Then finish up with the needle scalar in the pockets, inside edges, bolt holes, about anyplace the wire brush won�t get.. Those needle scalars do work good but not real good for large areas as the going is slow.. You�ll figure it out when you fire that baby up.. WEAR EYE PROTECTION as those thing throw chips & paint pieces.. I also wear a respirator as it creates a lot of dust from that old lead paint (not good for you).. Quote:--�If so how did it do and how long will a set of needles last?� --That depends on how much you use it & on what.. If I use mine a lot I get about 4-5 months on a set but I re-grind the needle ends to be flat so it works better.. If you use it on hardened welds or hard rough steel they will wear much faster.. I think you will find that needle scalar is a great shop addition but not an end all for large paint & rust removal projects.. BTW,, if you haven't bought one yet watch the cheap ones as they can be air eaters & use massive amounts of air CFM.. (that�s why I now have two).. Clooney
