Hi,

I have 3"x3" lumber and I would like to do one of two things:

1. Make a 3" quarter round, or
2. Make a "diagonal" cut so that the lumber has a triangular 3"x3"x
profile.
I have a table saw and a band saw.

Get a 3" piece of PVC and cut it in half lenghwise. Duct tape it to your
stock.

Feed the whole shebang through your table saw with the PVC against the
fence. Rotate the stock slightly and do it again. And again. etc.

Ultimately you'll have a 3" half-round. Cut in half.

I have no idea whether this will work.
