Joining Different Thicknesses of Material

[Randy Johns]

Hello...I am new to Kreg joinery and I like what it allows me to do.  I have build numerous shelf sets for my wife's classroom with relative ease.  I now want to build a small TV stand/entertainment center for our bedroom to build my skills before I tackle the big entertainment center I want to build in the living room.

All that being said, as I progress, I know I will have to join different thicknesses of material.  How do I use the jig to do this since its design appears to be focused on joining the same thickness of material together.  I have the K4 Master System.  I need advice on how to use the jig to join 3/4" to 1/2" among other thickness differences.  Thanks for the help!

Hi Randy! :)

I guess it depends on what size boards you use as sides and as tops/bottoms.

If the sides of your tv stand are 3/4", then use the 3/4" settings on guide and drill bit, then drill the holes in the 1/2" board.

Thanks James!  That gives me a great place to start.  I have plenty of scrap on which to test.  Should I use a shorter screw in this case?

Nope, use the 1 1/4" coarse screw for softwood or the fine screw for hardwood.
