If you make a square base, a good idea would be to make each side offset so that you can make a dado or whatever wider. Let's call the top the 12 o'clock position and that is that side that goes up against a straight edge. You could add a little bit to each side so that you can increase the width somewhat easily.
For example:
12 o'clock = 0
3 o'clock = +1/64"
6 o'clock = +1/32"
9 o'clock = +1/16"
or
12 o'clock = 0
3 o'clock = +1/32"
6 o'clock = +1/16"
9 o'clock = +1/8"
or
12 o'clock = 0
3 o'clock = +1/16"
6 o'clock = +1/8"
9 o'clock = +1/4"
I haven't built one an incremental base yet, but I saw it in a book. Attached is an example of what I'm talking about in case my explanation was confusing. |
