Years ago, I saw Norm Abram using a throat plate with replaceable inserts on his UniSaw. I have wanted one ever since!
When I bought my SawStop, I included the dado cartridge and one of their blank zero clearance dado inserts, which works fine, But at $40 a crack for every different dado width I may want to cut, the throat plates can get pricey.
Then, I found Ralph Bagnall’s “Insert Throat Plate Plans” ( http://www.consultingwoodworker.com ), and decided to give it a try.
Ralph’s plan (9 pages) is well written, and includes a dozen photos that detail each step clearly and concisely. At under $5, it was a bargain.
I did have to modify the plan a bit to suit the design of the opening for the SawStop throat plate. They have a stamped metal component at the front of the throat that I needed to account for, and their unique retainer system at the rear of the throat required a little finesse. SawStop’s throat plate is also wider than most others (it measures 15 15/16” length, and is 4 1/2” wide), so plans need to be adjusted accordingly.
I made the inserts out of scrap hard maple … one is set aside as the ‘master’ so I can easily duplicate them in the future.
Also, I intend to only use this with the stacked dado set, so I made no provision for installing a splitter or anti-kickback device.
