Default Lock Miter Bit

If you have a lock miter bit for 3/4 " stock can you use it for 1/2 " stock or do I have to buy a new bit.Stuart

Yes, you can use the 3/4" bit for 1/2" stock. This is a wonderful joint and once the set-up has been mastered it's hardly more difficult to make than a simple mitre.
Once the set-up is spot on for a particular thickness wood, make and keep a test piece for easy set-up when using that thickness wood in the future.

The set up will be different for every thickness you use it for. There is a point on the profile that has to be centred on the thickness of the boards.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Check out the Marc Sommerfeld Easy Set jig. It's made for his brand bits (yellow version) and Freud (red version). The jig has 6 points, each a jig for a different common bit, including the locking miter. It also has a dial to set the thickness of the wood. It costs a bit less than $30 and is very helpful and accurate for setup. Here's a video on how to use it.
I've tried other jigs, but this one is the best so far. You will need to measure the thickness pretty accurately, I use a dial gauge caliper for that.

The more I do, the less I accomplish.

Tom, his disclaimer states the yellow jig will only work with Sommerfeld bits. Do you use it with other lock miter bits?
