I'm doing the ubiquitous ww project: ZCI's for my dado stack. Made out of MDF, pretty proud that I got it to fit exactly in the throat and level with table. Nothing a belt sander and a defective drum sander couldn't fix....
Since I expected this to happen, threw the switch real quick and of course the dado lifted the insert. Had I not done this test, and been standing behind it and flipped on full power, I'd have a MDF ZCI embedded in my face. Delta 36-725, the stock insert has some sort of clippy thingy in the back to prevent this very thing. Even considering how a ZCI is supposed to work, my healthy respect of the default safety features on the saw result in me not using a ZCI unless I have some way of securing it. Had a extremely violent kickback once many years ago on another saw. That was, and will be, the last safety incident I have with a TS.
Looking for a low precision, doesn't matter what it looks like as long as it's cheap and easy to cobble together. I'm not that canadian guy that makes router lifts out of wood. I know there are folks out there that can carve/turn/route some complicated retainer thingamajiggers, I am not among that group of craftsmen.
This seems like a pretty common problem, surely some WW has cornered this market and is selling 5$ clip doo-hickeys for ZCI's? What's his phone#?
