A drill jig is super simple. Drill a hole in a piece of flat stock, move it
off center on your drill press the distance you want between your supports
and clamp it to the table. Drill your first spacer , place a pin in the
first hole you drilled and now place the spacer on the pin, drill second
hole, move spacer to next hole and so on. I attach a small angle to guide
the edge of your spacer strip while drilling. When all spacers are drilled,
trim the spacers to so you have just over 50% of the hole left so the tube
will snap in. Remember if you are working with 1/4" tubing you want a size F
or even a 17/64 because your tube is not a straight line but is on a radius
so a 1/4 hole won't work with a 1/4 tube, same for 3/8, or 1/2. Adjustments
have to be made.

It is exceedingly hard to thread through holes. You're better off drilling
the holes in a straight line, then sawing off the top piece of the hole,
then snap the tubing down into the notch. You want a bit more than half the
hole, so there's two fingers sticking out to hold the tubing down.
