Getting all the teeth lined up on a dado stack is hard enough without worrying about losing shims — that’s why Forrest dado stacks ship with magnetic shims. But you don’t need to buy the Forrest to get these shims; you can buy them separately and they’ll stay stuck to just about any steel blade or chipper.
Besides losing shims, there are a few reasons you’d want to buy magnetic shims: you’ve bent or mutilated your old ones and they need replacing, or you’re sick of dropping them into the bowels of your table saw and having to dig them out.
Available with 5/8″, 1″, and 1-1/4″ bores, the set of six magnetic shims contains two 0.010″ shims, two 0.012″ shims, and two 0.015″ shims. Pricing for a set starts at $12 before shipping.
