Nothing fancy, just some tools I fabbed up to do the job. First is a brake line strap fabricating tool. Just some stuff I had laying around the shop...some angle, a piece of square stock, a piece of round stock, and a hinge. I tacked the square and round stock to the angle as shown and then tacked the angle to a hinge to keep everything aligned the same every time you close it. You have to leave some space to compensate for the thickness of the material you'll be using. You can use stainless or mild steel. I use 18 ga. Just lay the angle on your vise jaws and press out as many as you want. I use a hole punch for the hole. Next is a couple of thread chasing tools. Ever had one of those bolts that had the threads messed up on the end or even in the middle. I made this tool to clean up threads in those situations. I took a cheap pair of pliers and tig welded a grade 8 nut to them and then cut the nut into with a hack saw. Now you can clamp the pliers on the bolt anywhere hold the pliers with one hand and use a ratchet to back the bolt out cleaning up the threads. The last one is a thread chaser I made by grinding a groove in the side of a grade 8 bolt and welding on a T handle. I use it to clean all the threads in engine blocks when I'm rebuilding one. I know I could use a tap to do the same thing, but taps are tapered and most of the time pointed and won't reach all the way to the end of blind holes in engine blocks. Besides this saves wear and tear on your taps.
