The rubber washer/grommet way works VERY well and in my book it's the only way to make doors and panels..
Marc of Sommerfeld's Tools for Wood
puts them in every set of router bits he ships out...
You can get them ACE hardware/HD/Lowes etc.
You didn't say what type of router you have and the gromment will not work in all routers but I do use a work around that works just as well if not better,, see below..
Some of the routers have a very deep hole in the harbor shaft ,you can put short dowel in the hole to support the grommet that works great also.
The key with the rubber washer/grommet is once the 1st. bit is put in the router table and the height is set, DON'T move the router up or down, and all your joints will come out right on the button almost no sanding needed,it works that well every time, it can be used for any match set of router bits..
I know this has been answered before, but I have searched and searched with no luck.
I am going to make cabinet doors, I have a set of bits, router a table and a bunch of scrap wood to begin the learning process. Somewhere, I saw a post with pictures where they used some sort of rubber washer to put on the shaft of the router bit to make sure each of the bits would be at the same height. I remember there were issues when you bottomed out the shafts in the router, when you tightened them down, they could move inconsistently. The rubber washer/grommet thing avoided this issue.
Did I remember correctly? What are these called and where would I find them?
Thanks in advance,
