Technical Easy circle cutter

OK so I needed to cut out a round plate , and did not want a pilot hole
that you get from a hole saw. So I tried this , and it worked out pretty good !
basicaly your still use a hole saw to make a guide in some wood
then remove the pilot bit , and sandwitch the metal in between the wood
clamp it and drill it out !!!

 

That also works when you need to cut a hole bigger than the original holesaw hole. I also use it while woodworking. Many time salvaged doors will have a smaller than standard lockset hole. Pilot from the outside instead of the inside!

 

Good one, thanks!

 

Good idea.

Thanks, that just solved a problem that I needed a fix for and all too easy too.

 

Thanks for the tip!

 

I used that general technique when I had to redrill all the gauge holes in my '29 ccpu for larger Wings instruments, a few years ago, and did not have to repaint the panel.

 

Now that's outstanding information! Thanks for the tip!

 

very very handy tip.

 

Simple solution for a frustrating problem.
Thanks.

 

I just use a hole saw without the guide drill in my drill press and clamp the metal down.
