Default Another Miter Lock Question

I just cut the miter lock joints for the corner styles on my present project. My question to those members that are familiar with the miter lock bits if they ever have to make a second pass to get the fit right. I don't recall having to do this before but today I did have to. The wood is QS white oak, I cut with the grain, the material is 3/4" thick and cuts are about 25" long. After making the second pass things fit alright. Just am wondering if this sounds familier to anybody.

Jerry I don't think this is uncommon when you are not using featherboards. It is hard to maintain perfect contact with the fence, especially when running the vertical cuts. The second pass just cleans it up for a perfect fit. This is also true when cutting rails and stiles for cabinet doors, if you are cutting in one pass.

Yep. I usually run the vertical twice.

Hello again Jerry.
I too have had to either lightly sand the joint or run it twice to make the desired fit. Things get even worse in soft woods for fitting. It's not YOU!. I can't think of very many things in life that are exactly perfect, except my wife!!! ahem, I had to say that!!

Get a lock miter set-up gauge from Infinity and you will be running perfect from the start.
Guaranteed.

I have both sized bits and the set up gauges that go with them, but that has no bearing on my question. Not trying to be smart, just clearing up what the issue at hadnd is. The set was done with the set up gauge and still took two passes to get the fit and the fit is fine after the second pass. I do thing that the fact that the white oak is so darn hard as a lot to do with my current problem. But thanks for your input.

I hate to tell you Herb, but Jerry has the complete Infinity setup, including their bits.

Any cutting tool I can think of causes some compressive forces when it cuts. A planer is a good example. You can run a board through at a single setting and it will always take a little more off on the second pass. The same thing is true in milling metal which is why many precision parts are ground to size instead. The same may be true of your lock miter bit, especially without feather 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.

LOL, Dick, so do I and love them. I have only cut plywood drawer sides, and they work great for that. I can see that the Oak might pose additional problems as was also brought out. Good to know in the future.
