Here's what I would do: * Pre-cut the holes on wood to the layout of your choice using a wood bit. * Clamp the wood to the metal with the wood on TOP. * Switch to the metal bit and then using the holes as a guide, make the rest of the holes in the metal. Note: You may need to drill out a small hole in the center of each on the metal one once you make once the wood template and clamp it to the metal. This should be done with a slightly bigger bit than the bit you will be using to make the button hole; with a normal drill. Then, when you drill through the metal using the metal bit, the wood holes themselves will stabilize the outside portion of the drill bit; since the metal center of the bit will not be touching anything.

Delusional - I think I get it now. I'm still a bit iffy though because I won't be able to use the cutting oil easily. I actually had a blank art 'template' and pre-drilled the pilot holes for everything (hence finding out the issue as kind of a surprise when I went to drill and the bit wandered/shifted unexpectedly). Based on that, I actually can make a single hole 'jig' I can clamp to the panel and to underlying wood and then use that in my drill press repeatedly as I can center it on the hole as necessary. Nice...very nice! I have a feeling I'm going to try 2-3 of the above options until I get it done. Luckily, my artwork/overlay will cover any mistakes and I should be able to 'fix' things with glued on metal backing or wood if necessary based on where the holes are. Thanks everyone. If work goes well tomorrow, I may take friday off to get this thing done. :) |
