Default 4"holes

I'm building a few homemade blast gates and want to cut 4" holes. I've tried freehand and don't like how the hole turned out. Any suggestions on a simple way to do it?
Thanks for any suggestions. Rick----

Hi

I use a hole saw for the ones I made using some scrap MDF you can also use a good cir.jig, it just takes a bit longer to make them..

Jasper cir. jigs, the 200 and the 400 in one combo kit.

Here is a zip file showing how to make a very simple circle jig, fine for occasional use but somewhere amongst my many threads is a more complex but more versatile jig.

It just opened OK for me Richard, if you can't open it now, just ask if one of the computer literate members can suggest why.
