Slide 1 - Micro Jig Presents: How install a Zero Clearance Insert on a Table Saw.
The procedures shown here may not apply to all table saw models.
A cost effective way to drastically increase the safety of your table saw and improve the quality of your cuts is to install a Zero Clearance Insert (ZCI). A ZCI will allow you to rip very narrow strips more safely than using your stock throat plate and will allow you to install our MJ Splitters or MJ Splitter Steel PRO.
You can purchase a ZCI specific to the make and model of your table saw. If there is no available ZCI for your table saw, you can use the stock throat plate as a template to make custom ZCIs from MDF with or without laminate, good quality plywood, UHMW or Phenolic.
Another way is to use “rare earth magnets” stacked to about 1/16” below table saw top surface so the bottom of the ZCI is not touching the carbide teeth of the blade. The rest of the slideshow will use rare earth magnets to demonstrate the ZCI installation.
For a snugger fit, you can drill and tap additional holes for setscrews on the side and corner of the ZCI. We prefer nylon instead of metal setscrews on the side so they won’t scratch the cast iron rim and more importantly they can be adjusted to exert tension for tighter fit like a mini feather board.
Secure the ZCI with a hold down clamp. Turn on the saw blade and raise it slowly to its full height.
Note: If your ZCI is concentric, rounded on both ends, you can turn the throat plate 180-degrees. This will allow you to create two kerfs, one for an1/8” full kerf and the other for Thin Kerf. And, if you are installing the MJ Splitter Steel PRO, create one kerf with a fully raised saw blade and the other kerf to where the blade is raised about 1 ½” inch exclusively for stock that is 1” and thinner stock.
