How do YOU find the hole?


I need to drill two armboards for arms that aren't commercially popular. What method / tools have you folks used to find the proper location to drill the hole to mount the arm in the armboard? Obviously, i'm looking for the most accurate method that is the simplest and costs the least : ) Sean

PS... I'm only kidding. I'd rather spend the money to do it right than to hodge-podge together something that will chew up records and spit them out :(

C'mon guys, how can you do this to me? I ask an "honest" question and these are the responses i get??? : )

Honestly though, i've got a couple tables here that i need to get set-up. With 6 different linear tracker's, i've not lost the faith. These tables aren't for me hence the "back-sliding" into pivoted arms. As such, i need to know what type of "universal" tools work most effectively at finding the right spots to drill various arm / table combo's. I'd like to keep something on hand just in case something like this comes up again. At the same time, i don't want to spend more than i have to as i don't intend on doing this on a regular basis. Know what i mean ??? Sean

I like to let the hole just find me.

Aw, c'mon Sean, that one was just too easy the way you asked!! Whady'a expect man?
