I’m not sure if tongue and groove is the correct way to say it. Similar to how those X style wine rack built ins look. With a cut made half way through the strips to slide together to form an X.
My problem comes from the cutting settings, if i choose an offset will it cut larger than a 1/2" (material size) out of the center or do i go no offset? i’d like for it to be a tight fit and just want to make sure before i ruin a big sheet of plywood lol
‘No Offset’ will center the cutter over the line it is cutting, so probably not what you want.
Create a rectangle the size you actually want, then pocket that, or do an Inside contour.
Pocketing may provide better results, since an Inside Contour may end up cutting a slot the same width as the cutter, and that can cause problems because of how much engagement there is.
Oh, and this kind of joint is an exaggerated half-lap joint - in a normal half-lap, the material is usually wider than it is tall, here it is much taller than the material is wide.
Yes this is exactly what i had in mind, i was getting confused so i did a test cut and outside right was the right choice for this, made them fit clean. Ill post pics when its done
