I made a new zero clearance throat plate for my Craftsman bench top table saw
and am having some problems with it. The first one I made from 3/4” oak and it
has always worked fine.
I made the new one from 3/8” phenolic sheet. It stands up on four allen screws
I threaded into the phenolic. I inserted a wire brad into the back of the plate
and cemented it in with epoxy to keep the plate from rising up in the back. This
is the same way the original plate worked.
After I raised the blade through the plate I removed the rip fence and turned the
saw on again. The first time the plate popped out and slid forward. I adjusted the
brad in the back to limit the amount the back could raise up and tried it again.
This time I standed well out of the way and turned the saw on again. This time
the plate popped out and was thrown across the room. I raised and lowered the
blade a few more times with the fence in place. After this, the plate stayed in place
for a few tests. However, I am uneasy using this throat plate until I better understand
The variables seem to be:
1. The thickness of the material (only 3/8”); and
2. The stiffer material (phenolic vs. oak)
Does anyone have any idea what the problem might be? Thanks.
