A trick or two of mine...
As some have mentioned, I used to get a piece of perfboard from Shack
with .010 centered holes and throw (well, C-clamp) that on my board
and go to town. However, since the holes were smaller than 1/16", I
would go through a lot of perfboard. (I was drilling _through_ the
holes on the perfboard). I went to price 1/32" bits, tho, and found
them to be ridiculously expensive, like $1.59 each. Yuk.
So, while rooting around in the basement, I found a box of about 100
small finishing nails, 1/32" x 1", with kind of a diamond shaped tip..
sharp enough to go through PC stock. Cut off the head, insert into
drill, presto... 100 bits for $1.59.
My 65536 Kopeks.
