Finally getting back to the shop after a way too long hiatus. Won’t explain, but had issues.
Anyway, I am attempting to make my first ever box-joint jig with:
sliding miter gauge
1/4″ × 1/4" DIY hardwood stock
A 1/4"-3/8" Freud Box-Joint Blade
First attempt, on scrap, was a complete failure and would not join at all. Second attempt joins, but I want to know how loose is TOO loose of a fit. On the end of a ~2-1/2" wide piece of hardwood, most of my joints have 0.012" to 0.015" gap (about 1/64"), when assembled into a box corner. FYI, the joint can fall apart via gravity if allowed.
Will TB3 basically make this a non-issue? Or do I need to ‘rinse and repeat’ for a tight/snug fit?
I built a similar jig for my router table. I have a different jig for 1/4" and 3/8" wide fingers. I did incorporate the fine adjustment for the finger width. I find that I like a snug fit for my joints. Also, I found the setting will be slightly different for different kinds of wood.
The jig I first made was a very simple, cross your fingers and hope you got it right kind of jig. NO adjust-ability. I’ll use for my first box, a Hoppes gun cleaning kit, that I want to change from its OEM cheap plastic to wooden.
My next project will be the above “micro-adjustable” jig, once I get to WC and/or HD and pick up the needed bolts, inserts, and knobs.
Here is the simple jig. You can see where I had to attempt it twice (by the cuts). Not very substantial and will not last long IMO, but will work for now:
