Hello to all, OK, I've not been idle since my last post.... But, I had a few more fixtures to build and I have now completed that task!.....
.. again, I'll ask one of our excellent moderators to post pictures... But, all of the item involved are displayed or attached to the GT table of, "Tears" or table of "Sobbing uncontrollably!" .... Anyway, there are pictures of the drilling fixture and jigs, and also pictures of the rivet set bar and guide, along with the "windy thingy" pictured earlier. Hand tools and my trusty digital calipers round out the items needed... A little about materials here as well, the spring steel I used is SAE1075 blue tempered with a number three slit edge.... That means it is just how it came off the cutter and will have a burr on one edge on each side... It is easily knocked down with a file... It requires a little more work on my part, but cuts the expense by 50%.... 1075 blue/black tempered steel is pretty desirable as it can be cut, and bent somewhat, but it cannot take a 90 degree bend, it will break! If you buy it soft, (annealed) you can bend it any way you want, but a subsequent heat treat and temper is then required, and of course adds to the expense... No sharp bends here, so we obtained the already tempered spring steel... SAE 1095 would also be a good choice, but probably overkill as it is stronger and just that much harder to work with.... I am guessing the steel in the original was closer to SAE 1050 or the equivalent?? The 1075 spring steel I have can be drilled with carbide tipped drills, and cut with a shears. Next step is to cut to length, and radius the ends, followed by drilling the necessary holes, riveting, then annealing the ends, and finally winding it up to install! More to come! Best to all, til....lat'r.....GT....
