[sdiy] Learned something today...

[Oren Leavitt]

Hi all,
I've dabbled a bit in pre-spaced PCB mounted pots, too.
Getting the hole spacing just right truly a pain in the toilet muscle!
I have found that drilling a small pilot hole, and progressively working 
up with larger drill bits, seems to help. I'll also check the spacing 
while the holes are small and see if I need to add in some 'fudge' 
factor to correct it when I drill again with a larger bit.
