Dear Dan:
Using a router in the same way as you describe for a jig-saw will also
work. If you choose to go the jig-saw rout, you will need to turn the
jig-saw slightly toward the center of the circle. I used this same
technique a few years ago, and if you have the saw at ninety degrees to the
center, the saw will pull away and in my case bend the blade. Using a
router avoids the problem which is created when a jig-saw blade attempts to
go in a straight line.
Yours Truly,
Clifford Wilson

Subject: [BlindHandyMan] Cutting a curve
So, what would be the easiest or actually most accurate way of cutting a
quarter circle out of a sheet of ply? Actually, a half circle will work
also. Since the radius of the circle is 3 feet 10.5 inches, diameter of 7
feet 9 inches, this fits nicely into a 4X8 sheet. I have an idea of just
making a strip of wood and somehow mounting a jig saw on one end of it.
Then driving a nail through the pivot point exactly 3 feet 10.5 inches
from the near side of the saw blade and then driving the nail into the
sheet somewhere pretty close to dead center near one long edge of the
sheet.
Since I don't have a jig saw at the moment I am not sure how easy it will
be to mount the shoe of the saw to a strip of wood. Is this the way to do
this?
Thanks.
