OK, I won't mention past this the stupid mistake I made and came THAT
close...

I have some small pieces of cedar to cut. They are already formed at
3 1/2" long, and 1 1/2" square ends. The problem is that one corner
needs to be more than 90 degrees. If using a table saw, this means
pushing them through a tilted blade for two adjacent sides to form the
larger angle on one edge.

Question ...how to do this safely? I thought of planing by hand, and
might wid up doing that after I've ruined a few pieces. Safety is the
issue. I made one mistake, and now look like I'm getting ready to
weld inside an old chemical drum with all the protective gear.

Thanks.
