I have an M12V which I used in my table for several years and it did an acceptable job. Having to reach under to adjust it was the biggest issue. Then I got an M12V2. It has above table adjustment capability. There is a 13 or 14mm nut on the end of the adjustment rod which is exposed once the black plastic base comes off. I use a 3/8 drive mechanics speeder wrench with a socket on the end and I can through the full range of adjustment in literally a matter of seconds. The V2 also has a wider throat opening and has plugs on the end of the spring tubes to make removing the springs easy ( takes maybe a minute). It really was designed to be used in a table but was never really advertised as such for some reason.
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.
