How to Make a Plywood Throat Plate for Band Saws
It is surprising how important is a tight throat plate to ensure successful sawing on the bandsaw. A throat plate with a narrow kerf that flanks the blade neatly will prevent small wedge-shaped parts that separate during the sawing process from jamming the blade.
Our Grizzly Band saw came with plastic throat plate that had unusually wide kerf. This plate agonized us for a long time, that is until I decided that it is time to make a replacement. I used plywood and cut the circular plate on the band saw. Then I shaped a rabbet around its circumference to allow it to sit flush with the band saw table top surface. Once the plate was ready, I cut the kerf.
The main advantage of plywood for throat plates is that you can easily rehabilitate it even after the kerf had been widened up or became longer with use. To do so I take the plates out, affix a strip of masking tape over the top surface, turn it upside down and pour epoxy into the wide irregular kerf. After the epoxy cures, I reintroduce the plate to the band saw and behold – the new-old throat plate had been re-born. Sure it is possible to spend a few dollars and buy an aftermarket plastic throat plates, (although it might not fit into every bandsaws model out there), but these plates cannot be restored as most likely it would be very difficult to have the epoxy adhere to the plastic surface.
For this reason, I believe it’s worthwhile to spend some time and make your next plate from MDF or Plywood.
