Yep, you made a fudge statement that I know from various cutting
devices isn't necessarily true. some blades do not like even being near
foreign material.
True enough for the foreign material. To answer your previous post first, it's been >25yrs
since I was working with a 10' sheet metal guillotine, and I don't recall the blade angle exactly, but
it must have been only a degree or two. Much greater than that and the grips that held the metal
down on the bed during the cut would allow the metal to rotate along the cut, and you'd have a
curved cut instead of a straight cut. I wouldn't have a clue what the angle would be for a guillotine
that specialises cutting copper/fibreglass laminates, as I've never seen one, but someone here
may be able to tell us. But then again, it's not really relevant to the original post, is it?
The op'er has the option of either taking someone's advice or rejecting it. He can take his
boards to a sheetmetal shop, or a pcb manufacturer (they do still exist in Australia), cut
it with a knife and a ruler, nibbler, etc, so long as he can get it done with the minimum of fuss.
