nope.. got no clue, but I like the sound of the hand punch for round holes... what's something like that cost?
I'm gonna glom on to this thread with a semi-related question of my own... I gotta mount ten 6x24" aluminum signs to a T-Stake post & that's 20 more pesk nut, bolt, and lock washer sets then I feel like messing with... has anyone invented a quick-connect locking pin for such lightweight demands like this? I'm picturing something like those barbed plastic pins used in automotive interiors so often... I've used zip-ties, but looking for a cleaner solution, and one not so easily damaged by sharp metal holes
