Like many older tablesaws, mine lacks a useful splitter, so I made my very own by extending the blade slot in a shopmade throat plate and inserting a small hardwood tab in the back of the slot. This isn’t a brand new thought, however I’ve refined the method to make it sooner and extra foolproof. I begin by decreasing the blade and bringing it up by means of a clean plate as common. This creates a zero-clearance slot that forestalls tearout on the underside aspect of cuts.
The difficult half is extending the slot safely and likewise precisely, so the tab will likely be aligned completely with the blade. I do that by placing the inventory throat plate again within the desk, becoming the brand new one over the raised blade (with the noticed turned off!), after which adjusting the rip fence to fulfill the sting of the brand new plate. Then I simply pop the plate off the blade and make a ripcut from the again finish as much as the prevailing slot. That ensures excellent alignment.
Subsequent I glue the tab into place, which closes the again of the slot and restores the plate’s energy. You may find the tab as shut as you wish to the blade for improved security. It’s actually that straightforward.
Just a few essential notes on the splitter tab: Begin by ripping a strip—utilizing the bandsaw or tablesaw—that matches the blade kerf. Then reduce off a bit and orient the grain vertically when gluing it into place, clamping throughout the plate for a powerful joint. Should you make a number of throat plates, you may have one tab that sticks up increased and one other that sits down low, for cuts that don’t undergo the board.
Final, I exploit a rasp, file, or sanding stick with take a spark off the perimeters of the tab so it doesn’t bind within the reduce, and spherical and taper the entrance edge.
