3 hole drill jig

[Frank S]

now for those larger plates,,too big for a jig,, u can clamp plates together,, or like we did making gravel shaker units, just tack weld them together,then
Drill baby Drill!!!!! and later of course grind off welds..which i think is faster than making a fixture,, especially if fixture is not going to be used again..

If I am only going to make a single run or parts then I will usually lay out 1 and use it as the jig for however many repeats I need to make.
But if I am gearing up for a production run of something which may be on going then a proper fixture is the way to go
