« Part 5: Hi, how have you been?!? It's been a while... Part 6 of Beads Box series Part 7: Fill, File, Fo - The filling of Them Pores »

While waiting for glue to dry I tackled the large drawer that will be faced with the mahogany/maple-stripe front. After the last project where I used dovetails for all the small drawer I wisened up (is that a word?!?) and went with box joint.

My box joint jig is based on my Incra 998SE Miter gauge . The 1000SE comes with the flip stop which is very useful with 2 built in stops, and a micro adjustment which I use to sneak up to a perfect box joint fit.

For added stability I also use the Incra Express sled which since I got hasn’t left my TS for cross slide – I can’t praise this one enough. It’s fantastic! That said, the concept would work even without the sled although it’s better to use one.

Now in this case I’m doing 1/8” fingers which means I am using my regular blade (I’m lazy and didn’t feel like swapping it for a 1/4” dado stack, and since the drawers are small, it will work just fine. for larger drawers it would mean a ridiculous number of fingers which then contradict my laziness).

I have a 3/4” scrap as an auxiliary fence that bolts onto the 1000SE t-tracks with bolts. The spacer that I’m using is a 1/8” drill bit that I simply drilled into the aux fence and released from the drill. for 1/4” fingers I use a… you guessed it – 1/4” drill bit:

I use 2 scrap pieces that I pick from the floor, or elsewhere (scrap aside, they do need to have 90 ends cut to stand properly on the sled/TS, other than that size is not important – all I’m testing is the thickness of the fingers not their depth, so the 2 pieces could also be of difference thickness/etc) and cut 3-4 fingers on each and try the fit.

If it’s too loose or too tight I use the 1000SE flip stop micro adjust (black set screw on the left of the stop) to sneak up to a perfect fit which either pushes the entire aux fence to the right, or creates space to move the aux fence to the left (after loosening the t-track bolts first of course):

Usually there is only a need to fine adjust this once to get a perfect fit that will hold the parts together but still allow glue to be added without making it all too tight.

This is really simple to make – only takes 1 scrap piece of 3/4” ply or anything else you have, and a drill bit. IF you already have the 1000SE. Simple to make, Simple to operate, precision and simplicity that is hard to beat – and I’ve seen other ‘jigs’ out there.

Thanks for reading,

Now I have another reason to buy the Incra 1000SE. Since I just got my new G0715P table saw less than 1 month ago, I had to put it on my future wish list. The future is fast approaching…!
Thanks for the hint Sharon and happy new year to you!

Great post. I like my Incra fence but I don’t have a slider because my slot is not standard. 1” X 1/4” with a 1/8” “T”

Very cool Larry, Incra is one of the few companies that I think each and every product is just a straight A++
