My fellow woodworkers,

I’m going to build a box joint jig for my skil router table. It already comes with a miter slot and gauge but I was wondering how to set it up. For example, How far from the bit do I need to set the key and so forth. Any suggestions would be greatly appreciated!!

Long story short, the bit, key and space between the bit and key all need to be the same size.
Why router table? IMHO, table saw box joints are quicker and easier.

Thanks ken_c! I had forgotten about that episode
NiteWalker: I have a craftsman saw that doesnt have standard miter slots. Im contemplating trying to figure out how to make them work but I have a router table that already has a miter slot in it. The miter slots in the saw have those little tabs that make everything more difficult. But thanks for the info I’ll try that.

home made slides work just fine. Make a sled box joint jig, there are a lot of free designs around. . Getting the right dado blade for the jig is a little pricey though. I’ve built a couple but decided to go back to hand cut dovetails and punish myself a little longer. You also might like the Green and Green style of finger joints. They are a lot bigger and easier to cut by hand too. I just made one for my chess set.

Not to stray off your OP, A couple weeks ago I found a post by WoodJediiNTraining that shows how to build a simple table saw jig. He also explains how to modify it to fit saws with tabs in the miter slots.
