Well, three or four months ago, someone by the name of Wayne posted a message on this board about a sale on Ebay for a set of tools called Swenchs. A Swench is a hand operated impact tool made by Curtis-Wright Aircraft Corp. It looks like an overgrown ratchet with a square drive sticking out both sides of the head.You pull on the handle againist a cam and spring and after about 30 degrees of movement something inside trips and the tool impact drives the socket. You can keep pulling for more impacts or push back and pull ratchet style. Well, I didn't get the ones that were for sale on Ebay at that time but since them I have made it my mission to locate and purchase 1/2, 3/4 and 1" square drive swenches. I finally got to use the 3/4 drive the other day and it works extremely well. I was removing the blades off a bush-hog and the nuts are on top, accessable thru a hole in the deck. Trouble is, they put the hole directly under the input to the gearbox, so its impossible to get an impact on it, and the threads were rusted. Couldn't budge them with a 3/4 drive breaker bar. I fitted the socket 1 5/8" on the nut and then just managed to get the swench under the gearbox input. The nut was heavily rusted but about three hits of the Swench and it was turning. Got them off, sharpened the blades, wireburshed the threads, nuts, etc., and removed the mass of bailing twine that had jammed the blades from swinging freely. Put it all together with antiseeze on the threads and used the Swench to put the final tighen on them. Thanks to Wayne, I had the forsight to buy a rare and useful tool. Charles
