While I was doing a refurb on a gas mono that was gifted to me, I came up with a jig to drill the rail walls. It is very helpful in aligning the mounts the same on both sides. Which was the problem with the refurb job.
Things were not lining up close enough for my taste. So filled them in with epoxy and started over. Here is a shot of the item I came up with. You just clamp it to the side of the rail and drill it out with a 90* drill bit.
I orginally bought some short bits on amazon. See below. The problem I was having was nothing really fit with what the bolt i was using. It was either too small or too sloppy.
That is when I came up with the idea to make my own. I had done this in the past for a work project with a piece of round stock metal that I machined a 1/4 hex on the end. Then just had a set screw to mount a short bit in. Since I could not find what I did with that tool, I need a newer and easier way to build one. I dug thru and found a chamfer bit that was broke that had the hex already (just like the unbroken one in pic). I was able to remove the broken bit and drill it out all the way thru with the size I wanted. Then cut the drill bit down some to shorten it. Then took some loctite 638 and glued it into the hex bit. Now I have a #18 short hex bit to drill all the motor mount rails till the cows come home.
