Hello. This is my first post here, and I'm not even what you would call a amateur yet, so bear with me.
I need to drill a series of holes in some pipe... but I need the holes to line up from one end to the other, in other words, when I put bolts through the holes, I need them to all line up in a plane... not like a spiral staircase.
Seems simple enough.
I bought a halfway decent drill press and a drill press vice, and set it up so the holes would be centered in the pipe... then I created a jig from some angle iron, so I could put a bolt through the first hole, and the jig would show me where the next hole needed to go. I figured with the vice holding the pipe, I would get what I wanted.
Well, I almost got it. When I was done, I looked down the pipe, and the "top" side of the pipe, all the bolt heads were in a nice line... however, the bottom ends are off randomly in different directions, so it ain't going to work.
Studying the problem, it seems like the jig is able to flip flop on the top of the pipe as I'm drilling... pulling the drill bit slightly off to one side of the other.
This weekend, I'm going to attempt this again. I am going to pick up a V shaped pipe drilling jig, and I'm going to make a new 'hole distance' jig out of thicker steel and clamp it to the press table under the V shaped pipe drilling jig. By bolting a bolt into the 'hole distance' jig, I hope that I will get a perpendicular line of holes drilled in the pipe.
Does this sound like it should work, or is there a particular technique for attempting this? Thanks in advance.
