Drill/Tap Guide Block for 15mm aluminium plate edges.

Just as an aside.
If you had swung your pillar drill over the side of the bench and clamped the plates underneath. The job would be finished by know, at no extra cost. :)
Nice design and animation though.

Hehe. Nope - I'd have screwed things up royally and would be saving up for another chunk of plate...

I did have a go at a bit of tapping through plate a little while back and by and large was quite pleased with the results I managed to achieve - but even after spending a great deal of time and care to get things square I noticed that the thread at the exit was lop-sided (noticeably shallower on one side) - it still accepted a machine bolt well enough and didn't show any signs of weakness - all the same, I'd be OCD-ing about whether I'd done it properly or not. I'm weird like that...

Cheers.
