Topic tags/keywords: question jig

I’ve got this bit and until now haven’t had the chance to use it. The one thing I wasn’t sure about was doing the sides. I did some googling and found a website demonstrating the use of the bit, but i”m not to sure about his solution for doing the sides. Clamping a piece of scrap wood on the back just doesn’t seem very secure. Any thoughts?

The website is here:

I had originally thought of making a jig that would hold the board vertical and just slide on the table, foregoing the guide and the miter gauge slot and just using the safety pin.

I have one of dem dere bits and when it’s right, it’s right on. However, getting it right is no small feat in my experience. I’ve used featherboards and jigs and stuff, and it’s always hit or miss. I’ve put mine on the shelf where it sits quite comfortably. For me, it was more trouble getting it set up and then cutting the joint, than it’s worth.

Russel – I had to laugh at how closely your advice about the bit matched the advice in your signature line!

Here is another discussion on the bit.

I was just thinking about getting one of these. Any other user reviews?

I have the square style of that bit shown at the bottom of your link and it is easy to use once you get use to it. Clamping the board does nothing but keep your sides from tilting which can happen somewhat easy so you should use it. The main thing is to experiment with scrap until you have the settings just right for the thickness of stock you are using and then save that scrap for future setup. Using that piece of scrap will save you much time the next time you use that bit. I also use mine for edge gluing panels. it adds about half again as much glue area and that joint will never come apart. Just be careful and don’t get in a hurry because you are taking a fairly large bite out of the wood.

The best on the lock miter bit is on John Lucas has the best demo on how to set up and use this bit. It works every time. I know.

The setup isn’t really that difficult… I believe the ease of use comes from utilizing jigs to support the workpieces during the monstrous bites taken to shape the joint in one pass.

The legacy site of has several great demos where the key info shows the jigs to keep the cuts consistent when using the lock miter bit.

I’d like to have one of those jigs but choke on the price. Doesn’t look like much there for 50 bucks. I already have the bit. Takes a little tweaking but once it’s set works good.

While setup jigs might save a few minutes of time, it is the stability of the workpieces while passing across the bit that makes or breaks it. I will make the push block set as shown in workshopdemos and give it another try.

And now that I’m thinking about it, why can’t the shaping with this bit be done in 2-3 lighter passes? For other cuts on the router table that would bite too deeply in one pass, I use 1/8” hardboard as either a series of tabletop shims or as fence shims…eg. 3 shims for first pass, remove a shim for second pass, remove another for third pass, then final pass with workpiece on table and against fence. I think it was Pat Warner that suggests that approach so that bit height and fence position are set once, yet you sneak up on the final cut.

I use this bit and have had a lot of success with it.

Once you have the proper height it works at the same level for the sides and fronts and backs. I have set up blocks I made to get me close to the final height.
