hey i know you aren't drillin it or whatever, but whenever you do, just put 2x4s on the bottom (make it level, but make sure they are under the holes) then pop a hole big enough for the bit in some Styrofoam (like the side of a cooler) put it where you want it, pour water in the hole turn the drill on the fastest speed and when you start let the weight of the drill push it through.....
that's how i always do it and it works great..... i mean i put 3 1.25" holes and 3 1" holes in the back of a 15 gallon aga. matter ir fact i drilled a 46 bow just the other day 4 times for that way and it only took abt. 25 min........
