Hmmm, I have this collection of Hollywood bed frames. All that
angle iron, just setting there ...

Bed frame can be some really nasty stuff to cut and drill. Supposedly
the dregs of metal mixtures. You may drill a hole or two just fine and
then another in the same piece is hard enough to ruin the drill bit...

So plan on it being a hassle and maybe you'll get lucky
