Tip for Roto-Zip saw users


Whenever I've used my Roto-Zip to cut figured patterns in plywood I've always been frustrated with how much splintering of the bottom edges of the cut line occurs. The other day I tried something new to reduce this problem and it works really great.
I used a sheet of foam insulation as a backer to the 1/4 inch plywood that I was cutting. I set the depth of cut so that the tip of the Roto-Zip blade cuts into the foam, but doesn't exit the bottom of it. The foam insulation holds the edges of the cut line and almost totally eliminates the chipping of the bottom side of the plywood. The foam also collects and holds much of the sawdust, and it doesn't seem to foul the Roto-Zip blade. It also allows you to put the whole project on top of the workbench and not have it hanging off the edge to allow for the blade protrusion from the bottom, so you don't have to worry about hitting your workbench with the blade. You can also re-use the foam panel many times before it gets so many cut lines in it that it's effectiveness is reduced.

This is a great tip as well when you're trying to cut large sheets of plywood or any sheet good on the floor with a clamp guide and circular saw. this way you don't need to raise the piece up, just place it on the foam and cut away.

A really great tip. I think most of quickly realized that it has uses well beyond the rotozip. Thanks.
