How to use punch holes in a metal cp
mccoy178:
Since this is my first attempt at working with metal, I thought a little tutorial could help future noobs.
First, I mounted my artwork to the 16 gauge aluminum:
I then cut the dog ears off the control panel and the edges to pretty it up using this tool:
I purchased a 3/4" greenlee punch that actually has an inside diameter of 1 1/8th". In order to use the punch, a 3/4" bolt is used to pull the two halfs together to finish the hole. The following pictures are of the greenlee punch new and the drill press with the drill bit ready for action. On a side note, while drilling the holes, there was some minor marks made on the art from hot shavings. This could probably be avoided with a clear piece of plastic over top for protection.
Here is a pic of the holes after predrilling is done:
Here is the greenlee punch on a sample piece. I used a 1" wrench to tighten the two sides together. It worked like magic!
NOTE: 1 1/8th is not big enough for leaf switch buttons. I used a drill bit to hollow out the holes big enough to get the buttons to fit.

Here is the cp after the punches were made. The extra material is just little pieces of the artwork.

Nice job.
But what is that drum major doing with himself on top of your buttons? ;D

he is very athletic! I'll leave it at that.

I used a greenlee on my cp also (it's awesome). Just one question/comment... wouldn't you have been better off putting the artwork on after the holes were punched?
I guess it might not even matter. Anybody else have a comment on that?
