I am planning to make some wine cork trivets. See here for an example:
I plan to make the 4 sides of the trivet out of cherry with a roundover
using a 3/4" roundover bit on my router table. I have been making a
prototype out of pine to see what issues I run into. There is no problem
making the roundover cut. The problem is when I go to the tablesaw to cut
off the rounded over part. If I place the rounded over part to the left so
that the flat side of the board is up against the fence, I run the risk of
having the cut round overs being slightly different width which will not
work when I miter the joints. By this I mean that I will cut off the rounded
over piece from the board, take it back to the router table, make a new
round over, and then cut that off etc. That entails moving the fence for the
now narrower board each time, If I place the rounded over part against the
fence, I have a possibly dangerous cut to make with a thin strip of wood up
against the fence. Having said that, I tried it anyway with appropriate push
blocks in place and the cut doesn't come out even. I'm not sure why it is
not coming out even (meaning that one end of cut off rounded over piece is
wider than the other end). Even if I can figure that out I am still spooked
by making a cut like this.
I thought I would ask the group members what your suggestions might be.
Using the same principe that Jack pointed to, this is another of the
million uses of a combo square. Place the square on the table so the
machined flat edge is in the table saw groove. Set the rule out the
appropriate distance for the repeatable cut. Now you can slide the
fence over each time with the stock in place until it butts the end of
the rule. Then you can set the square aside quickly so you don't have
anything dragging during the cut, rinse and repeat.
