I have been sucessful at getting air tools that lost power back up to par usually by a good thorough cleaning, and sometimes replaceing the vanes, however I have an air rivet gun (air hammer type) that I just can't seem to get to wok no matter what I do to it. No vanes of course, no bearings either, but all it does is set there and basically makes a vibration or an occasional blow.....
This air rivet gun let me down at the most inoportune time.......I had a 16 foot flat bottom john boat that I cut a section out of to turn it into a 10 foot boat for use on my smaller pond as the 16 footer was just too large and awkward......I had all the holes drilled spice plate all cut and fit, and ready to shoot with some aircraft rivets......4 rows of rivets spaced 5/8" apart 2 rows in each half of the boat, through the splice plate and also an internal doubler. Mixed up my sealant, a rubberized coating thats super strong has a work life of approx 1 hour........Spread a coat of the sealer on the boats portions, the main splice section and doubler, Kleco'd it all together, and started to shoot the rivets............after the 7th rivet the gun died........what a mess to say the least........I was using #4 rivets, button heads, and in the end wound up having to set them all by hand with a bucking bar and ball pein hammer.......the boat does not leak but the rivets set, and flattened heads on the rivets, leaves a lot to be desired, certainly not one of my better jobs I have ever done.......Since then I have torn that gun apart probably a dozen times, and have yet to get it to function. Its a good quality tool, with very little use.........not the typical HF type tool. Visit my website:
