I need an air staple gun to shoot an 18ga., 1/4" crown, by 1/2" length. But, the driver has to protrude 1/2" past the end of the nose. Of course, there's nothing like that available, nor is there a long nose gun that I could just shorten the nose by 1/2" available. I need at least 1-3/8" finished nose length to get clearance.
We need to repair single bad tufts in flat wire brushes. When the machine, operator, wire or other thing screws up and makes a bad tuft, we repair the tuft rather than scrap the brush. Years ago, I modified a BeA staple gun very easily by shortening the piston, and lengthening the nose and the driver. The BeA is now obsolete (of course!) and trigger parts and bi-material pistons are nowhere to be found ANYWHERE! My staple gun guy sells me $1k/week of ballistic screws and is motivated, knowledgeable and I trust his scrounging ability. The BeA was his idea years ago and he gave me the gun and all the parts over the years. I trust him enough to not even bother looking for parts myself. The new BeA that replaces mine uses a disk piston, the cylinder is part of the casting and is a very bad choice to modify.
So, his latest idea is use a Senco gun and make a longer cylinder, a spacer between the body casting and the rear cap to accommodate the longer cylinder, a longer driver and longer nose pieces. With this strategy, we can make any length nose and any length over-stroke. And, Senco should be supplying parts for many years.
An ideal project that won't take too long, demand some precision, won't cost very much and have immediate pay-back. I've got about 25 barrels of repairs to do. And, since I'm making ONE, I'm going to make TWO or THREE for very little more time and money!
