Now that there is a woodworking forum, I think we need a place to put tips etc. all in one place.
I‘ll start with with this one:
I’ve made a quite a few boxes as well several machinist chests that require thin stock to be used for dividers.
I also use thin stock for reinforcing the miter joint on picture frames.
Over the years I‘ve used several different methods of cutting this stock accurately and consistently but the following one is now my favorite.

Obviously it’s not an original idea but here it is on my saw.

For the spline stock I just used on two large frame I measured the slot I cut using a #30 drill (.128”).
Cut a test spline and found it to be too snug with glue applied.
Substituted an 1/8” bit (.125”), recut a spline and it was perfect!
Way quicker, and easier than other ways I’ve tried.
Not shown but I remove the square and substitute a feather board before each cut.
