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.


We are glad to be of help, Glenn. And we can't wait to see the finished project!

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

Miter Saw Recommendation 1 Reply

I’m looking to upgrade my miter saw. I’m willing to invest a good amount of money to get one with the precision pocket hole joinery requires. Would anyone like to offer a recommended model?

New Kreg 720Pro

I saw the video Kreg put out for this new jig and had high hopes for it.

I purchased one today and am very disappointed with it.

First the docking station is extremely cheap. The plastic is pathetic. A Lego has more…

Not Pleased With Pocket Hole Construction

Several months ago, I purchased the Kreg K4MS so that I could build the Lego Table as outlined on the companion "buildsomething" web site which exclusively uses pocket hole construction.  I have considerable experience with conventional…
