homemade dice valve caps

started with a 5 pack from dollar general. ended up with three complete. on my first try I used a 3/8 bit with a strip of tape to mark my 1/2" depth. when I tapped in the cap, the dice shattered. moved up to 25/64 too much pressure on the drill, went clean through. third try got it right.

use soapy water while drilling. will go through like butter.
