Piano Key switch grommets

OK. Quick shot of the short cut.
This is a GREAT idea,...so long as you don't mind two tiny little holes in your plexi panel.

I got a picture of his panel and thought I would share it here for the next person interested.

dstates, So, I may follow your process. I have a couple follow on questions.

How did you find the exact locations to drill?

How many screws must be removed to remove the switch / fuse panel?

Thanks, Cory

Cory,

You only have to drill through the plexiglass in two spots if you want to remove the piano keys without removing the controls. I believe there are eight total screws holding on the piano key assembly. Here is a picture of mine after I made my change to circuit breakers. Unfortunately I had some bad luck and actually broke my panel drilling the second hole after drilling the first one perfectly. I’ve since learned there are bits especially for drilling plexiglass. I used a standard drill bit and it caught for a second and broke my plexiglass. I’ll eventually end up replacing it, but I’ll wait till I’m ready to address control replacement. But it isn’t too noticeable unless you look at it from the view the picture was taken from.

The best way to locate the two hidden screws is to know that they are directly above the ones below the center “key” and in line horizontally with the top corner screws.

It has been beneficial having access to those screws as I had to replace a master switch last winter and I was able to remove the piano key assembly. I would totally do it again, just with the correct drill bit next time.

Hope this helps.
Doug

To drill thru plexiglas without cracking it out… take an ordinary bit and grind the end flat …. to remove the “rake” or point.

Great information!! This is definitely going to benefit me going forward. I'll try to get some pictures to share also.

Thanks!!

Step drills also work well on plastic and composite materials.

Doug, looking at the crack in your overlay…. it appears that your overlay is clear…and not painted on it’s back surface.. Is that correct?

George, I believe it was painted. I used double sided tape to re-install the cracked piece.
