Review: They said it couldn't be done - I was looking to get into small box-making in the simplest way possible. I used a portable router, with an array of portable tables and jigs. For 1/4 inch joints, I started with a Dewalt 600b cordless router, a Bosch portable workbench, a Rockler Trim Router Table, a good carbide spiral up cut bit, and and this Rockler Box Joint Jig. After several days of experimentation, I came up with some pretty good, repeatable box joints. The procedure is as follows: 1) Clamp the Router Trim Table to the work bench. 2) Loosely clamp the Box Joint Jig the the Trim Table. 3) For 1/4 inch jigs, I used a 0.25 drill bit to set the distance from the 1/4 inch brass key to the router bit. A set of feeler gauges can help zero in on the distance. 4) Clamp everything tight. 5) Use a digital gauge to set bit height. Set the height roughly 0.010 more than the mating material thickness. I used a Wixey WR25 3" Mini Digital Height Gauge. This gauge really makes things easy. 5) Press work piece tightly against brass key, and make a test cut. 6) With a 1/4 inch joint, that first pin thickness should be 0.245-0.250. If the thickness is less than 0.245, the fit will get sloppy. If it is more than 0.250, it will be too tight, and the joints will not go together. For me, about 0.248 is the sweet spot. Get some digital calipers, and learn how to use it. 7) A second cut isn't necessary to dial in the fit. Loosen the clamps, and tap the Box Jig left or right as necessary to achieve the 0.245-0.250 pin width that you are looking for. 8) After the first cut is dialed in, make sure subsequent cuts ae made by pressing the workpiece tightly against the brass key. The key is only about 0.243 inch in width, so this step is important. The 3/8 and 1/2 inch joints follow the same procedure. This method is working for me, particularly for small, one-off projects. You would want something more substantial for making larger quantities of joints. I want to stress, that using digital calipers, and a digital gauge for router bit depth really help make this, or any other project less frustrating.
Review: Works great, read review for super secret info - This jig works great. There are a few small flaws in it that I'll probably DIY fix to make it even better, but that's not the reason I'm leaving this review. I couldn't seem to find this info anywhere in the instructions, even though it is so obvious when you think about it-- When you're setting up the key, it needs to be exactly the distance away from the bit as the width of the key. Meaning you need setup blocks. I didn't have a set of setup blocks. I was upset. I just spent all of this money on a jig and now I need setup blocks to even use it? I looked at the jig and figured out that each key is tapered, but the taper only runs on the right side of the key. The left side is straight on all of the keys, and the left side is the side that you measure for distance from the router bit. This means the left side is the side that matters. So here's the super secret info that they didn't put in the instructions- This means the if I want to use a 1/4" router bit with the 1/4" key to make 1/4" fingers, I will fasten the 3/8" key into the jig. I will then use the 1/4" key as the "setup block" . After adjusting the jig and securing it, pull the 3/8" key out and replace with the 1/4" key. Now the jig is set up for 1/4" finger joints without setup blocks. Why that little bit of very important info isn't in the instructions is beyond me. I setup the jig like this and made perfect fingers without having to readjust the width of the fingers. I just set it and began production on the project in the attached picture.

## Questions & Answers

**Q: can I make .125" joints with this kit?**
A: It does not come with a .125 spacer but you could make one.  It could be made of metal or hardwood perhaps and you would have to find a .125 upward spiral milling bit.  Do not use a rabbiting bit.

**Q: Is there any horizontal adjustment to make the tongues wider or narrower**
A: The jig comes with 3 keys: 1/4, 3/8, and 1/2 inch. You can probably fabricate other sizes in between, but the jig is not big enough to accommodate much lager keys. They have another jig for that.

**Q: This picture doesn't match the one on rockler's site -- is this an older version?  which one will i receive if i order it?**
A: They only make two models, this one and the XL version which also does 3/4 cuts. There is no 'older' model.

**Q: I have a milling table and the distance from the strawberry to the rail where the rockler box joint is squeezed is 13.5 cm. would it be worth my table**
A: Router Table Compatibility: Near edge of router table's miter track must be between 4-1/2'' and 6-1/4'' from the center of the router bit

I like what this jig does but you really have to do a lot fine tuning. Once dialed in it seems to work pppretty good.
