Phil, great looking boxes, and box joints too. You are a craftsman, I just think that a beginner would do better learning how to do box joints on a table saw. Maybe I am wrong, but the cutting of the box joint is the easy part, laying them out and making them tight is the tough part. If you are off just a hair on the first one the second one is off 2 hairs and so on till the last one is off so much that they don't fit together. And where you start on which edge of the board, and on each end of the board so you don't get one board up and one board down
Thanks for the compliments. Much appreciated.
My experience is exactly backwards from that, though. Not saying you are wrong (because you are pretty much always right), I just went a different direction.
About a year ago, I made my first box joint with a home built jig on the table saw using a dado blade. Results were disheartening. I was able to tune it up so it would work reasonably well but never got joints that I was super happy with. And making 4 sets of cuts exactly correct was a challenge. Version 2 jig was also on the TS and while it was better, set up and tuning were required each time I used it. So I made a couple of boxes for the shop but nothing that I felt was "brag worthy". One of the key issues is you have to move the workpiece(s) to the next key location which makes it hard to have super consistent cuts - each cut requires exact positioning and pressure. That makes it way easy to get the cascading errors that you pointed out. Also, while the dado was mounted, the TS was out of commission for normal use.
Then I got the LS system for my RT. HUGE difference. Fast set up, precise repeatable cuts and my TS was usable at the same time. The way you clamp the workpieces makes for a very consistent depth of cut, angle and position relative to the fence. There was a relatively small learning curve but now, with the cut workpieces in hand, I can bang out a complete set of box joints in about 20 minutes with the LS. Set up is just a few minutes and the cutting goes very quick. It's not fool proof but Incra has done a great job of making it easy to be consistent - you just have to be within 1/32" and it locks you into the correct position every time. If I were starting all over again, I'd go straight to the LS or similar positioner and do them on the router table.
