Using a metal hole saw on aluminum

I thought I needed a little bigger hole for leaf switches?

I have just seen through using the search tab(amazing huh?), that the only reason 1 3/16th holes are needed is due to the little triangle tabs on the bottom side of leaf switch buttons.  I also read that one of the members used a hobby knife to cut those out, so I'm going to give it a shot.  I also attempted to fit one of the leaf switches into a hole on my old microswitch control panel and it went in snuggly.  I plan to make a full tutorial on this once I have the products in hand.

BTW, does anyone know what size greenlee punch is needed for the trackball?(I measured 3 1/8th myself).  I don't know what size greenlee punch that would be.

Which TB do you have?  Almost all 3" TBs need a 3" hole.  AFAIK, only Happ's HighBall model is different, and needs a 2.25" hole.

Hi there,

My control panel modules are aluminum and I haven't had any issues w/ it although I do not have artwork on the modules (yet).  It actually cuts pretty clean and easily and I'm using a handheld drill w/ hold saw.  It is MUCH better than what I had previously which was plate steel.  Yikes   :dizzy:

I'm surprised that it's aluminum and not steel.  My original control panel was steel.

I just made a little tutorial on how I made my holes.  They were a hair too small for the leaf switches.
