joining 3/4 inch plywood to 1/2 inch

[Glenn Nugent]

Hi,

I am working on building a home entertainment unit.  My main material is 3/4 and my backing is 1/2.  I am planning all of my joints Joining 3/4 to 1/2. On the jig I set for 3/4 then use screws for 1/2 correct?

Glenn, what you are doing is correct. You always want to set your jig for the thickness of material you are drilling into, which is 3/4" in this case. And then use screws for whatever thickness of material you are screwing into, which is 1/2" in this case. Since 1/2"-thick plywood is never quite 1/2"-thick, you may want to test it out on a piece of scrap plywood before you drive a screw into the material you are using for your project.

Great thanks for clearing that up for me.

This is my first project using the Kreg Jig and I am really impressed.  When I am finished I will submit a photo.

For the 1/2" backing would you use a 1" screw through the 3/4 ply into the half? I'm making a similar unit
