Using the Lock Miter Router Bit

Chris
I have one and have never been able to set it up for anything less than 3/4 inch stock. I got a set up block from Rockler but unfortunately the bit was not from Rockler so no help there. I suppose a lot of patience would pay off.

I got a bit and a set-up block from MLCS, but I haven’t tried it yet.

http://www.woodshopdemos.com/cmt-lm5.htm has a pretty good method of setting up. once you get it right save a sample to make it easier the next time!!!!

Hi Chris,

Although my bit isn’t from MLCS, the setup procedure is the same. The first video in my pool table series covers the setup of the Lock Miter bit:

there is a leaning curve with the LMB. cut the piece in 2 or 3 passes and be sure to use a push block that supports the work piece to prevent tearout. I made a block from a 2×4 with a rabbet cut out at the front the same thickness as my stock [ 1/2” ] and about 3/4” deep. I put a grip handle on it. the work piece sits in the rabbet. this way I can push and hold to the fence at the same time. the push block also backs up the cut. I always mill my stock to the same thickness so I only need one of these. if you use other thicknesses make a few more blocks and size the rabbet as needed. when one block gets torn up at the cut you can rip some off that edge and its like new again.

BTW I didnt buy the setup block either! fiddle with scrap till you have it set up as close as posible then make a setup block for the next time.

Thanks for the Link John!

Skeez… I like your method; it’s far more economical than purchasing a dedicated coping sled or other such jig.

I was a little late to this discussion, but I thought I might add my 2 cents. I recently found an article about using lock miter bits to create quadrilinear posts in the mission style, but I can’t find it in my files. Here’s a link to the article:
