Just bought a Ridgid R4511 saw… Great Saw!!! 1st project was a zero clearance Dado Face plate… need to make more. Second was an Adjustable Box Joint Jig that was featured in ShopNotes “Table Saw Tough Cuts Made Easy” magazine. It’s an AWESOME jig that is basically a sled that rides on the two miter gauge slots. You make a different face plate for each size slot/pin. The jig works FANTASTIC. I have a face plate that is for a 1/2” slot/pin and can build more for different sizes of slot/pins…

My question is before I make other faces for different sized slot/pins, is there a way to determine what size slot/pin to use based on the width of the pieces. Hopefully, I am describing this correctly… (this my first trip down box joint lane). My desire is to have the pins/slots to be correct at the top and bottom… how do you know how to select the cut so it will come out on top and bottom correctly??? The ones I’m making now have a full pin on top but the bottom comes out to a partial….

Next step will be to make several drawers for a planned bathroom vanity, a tool storage cabinet and a built in storage unit… but I’m not smart enough to fine tune the pin/slots …

I truly appreciate any help you may throw my way…

to get even amout the wood has to end in the same number like if your making 1/4” ones the wood has to be 3 1/4” wide the same for 1/8” – 1/2” and so on if u go to woodmagazine.com they can confirm what i’m saying just look up box joints, or even number of box joints. aslo u can cut the one thats a half pin off to make it even too for this you want to start with a wider piece of stock. GOOD LUCK! hope this helps.

This is so cool, I just, and I mean just finished the exact same jig. My first test run was perfect. I chose a 1/2” index pin for 3/4” stock. It looks right so I’ll use the same 2/3rds ratio for other fences. The very next article explained everything you need to kknow about pin placement. Did you have any issues with getting the miter rails and base to a good fit? I ended up using several layers of tefflon tape to fine tune mine.

DOH! I guess it would help if both pieces of wood was the same height… forgot I had a piece of scrap 3 3/4” for one piece and a 4” for the other… no wonder they were off… Dumb, Dumb, Dumb… Hey Rustedknuckles… isn’t it the coolest jig?? I just made the one face plate for the 1/2” Dado… Headed to Lowe-balls for some more 1 X 6’s to make more… The 1/2” dado cut looks a little too big for the pins I’m wanting… I didn’t have a problem with the miter rail fit… slides perfectly and my saw has the granite top… Smmooooooth… I used 3/4” pine for most of the pieces… hopefully it won’t swell/distort… didn’t have any 3/4” plywood handy. Thanks, Big Ike for your input… that makes sense!!

It is cool. I had some baltic birch plywood so I did it exactly as described. I also built the tennoning jig and the simpler of the thin strip ripping guide. I really liked the ripping guide they did with the bearing guide. i think I have an extra bearing like the one they used so once I find it I’ll try that one too.

It really is a handy group of tips… I didn’t put on the adjustment screw and hardboard on the side of the box joint jig… do you use it much?

I’ve only just finished it so other than testing it I haven’t had a chance to work with it. I did put the adjustment screw in mine but I didn’t need it for the test cuts. Now I need to invest in a better dadoe stack, my current stack is chipping out bad. Did you look at the companion CD?

Here are a few shots of my interpretation of the jig.
