Attached is a rough drawing of two pieces of angle iron welded back to back to form a V to hold a piece of round stock while drilling a hole in it in a drill press if you do not happen to own a drill press vise. The plate at the bottom can be extended so that it can be clamped or bolted to the drill press and the bottom of the v allows you to align the drill bit to the centre of the work piece you are drilling. It can be used for solid stock or pieces of pipe to give a reasonably accurately centred hole in the work piece and a large hole can be drilled in the centre of the v so the drill bit can pass through the angle iron if so desired. I once saw a set up like this in a shop and have thought about making one but never got around to it.

I made 2 several years ago out of 3" square wood. Used the table saw set to 45° and cut a V out of one side. Center the bit to the bottom of the V, lay the round stock in the V and you will drill dead center of the round. Works about the same as 29 chevy. Another handy tool is use a 3" square piece of plexiglass, mark the center by the intersection of the two diagonal lines from corner to opposite corner. Using a compass with two points, scribe a circle every 1/2", or 1/4" if you have use for that better. Drill the center point out with a 1/8" drill. To drill the center of a piece of round stock lay the template over the end of the round so a scribed line is even with the outside diameter. Mark the center through the hole in the template. I like to use the Sharpie dual end felt markers as they have a fine on one end and extra fine on the other.

Both great ideas! Not all of us have access to precision equipment!
