Here's how I look at where to put a track..
If I have a featherboard that has a 4" reach, I'll put the track in so that I can put the FB up to the bit, with a little room to spare.. Let's say 3.75".. You can also take into consideration if you are going to use a miter gauge..
It really doesn't matter where you put a track in, just as long as you're comfortable where it is.. On my present table, I don't have a track in it, as I found I didn't really use the one I had in the old table top.. The FBs I use now are made of 1x3" oak that I just clamp to the edge of the table.. |
