Default Best Way To Cut Hole for Tach?

Hey, I want to get my hood tach installed on my 69 Firebird. I have the template and know where to cut -- but what's the easiest thing to cut the hole with?

You clean the surface, lay down some 3M tape over the area to be cut and mark it off...for a smallish hole like that, you'll either want to use a sabre-saw with a high tpi count or get about 6 "cutting" drill pieces for your Roto-Zip and use the circle attachment...although never recommended for metal, the hardened bits do a good job cutting metal but they break as they get heated, hence the need for quite a bit on hand for the job. :cool:

Hey Tony,

Yes, I think you did give me a template. I now have a few counting the one that came with the tach! :rolleyes:

I purchased a hole saw today but the closest size I could find was 3 1/2. I need a hole 3 3/4 big. I think I'll use the hole saw and then trim the remaining 1/2" with the dremel.

I'm assuming you both said to mask the hood to preserve paint -- I'm in primer at the moment and will have to touch several areas up anyway.

Thanks a ton!

John

It will prevent unnecessary scratches to your primer coat, too, and will ensure the primer isn't chipped or flayed away from the cutting area...
