ZCI from a ZCI

A couple years back I picked up one of the Leecraft ZCI’s and have loved it ever since. It fits my tablesaw perfectly and the adjustment screens make sure I get it dead level. However, at ~$25 a pop it would get expensive to have one for each blade, especially if you think about a dado stack. And after a few years of use, mine has certainly seen better days. In the past I’ve just made my own out of 1/2” MDF, but to get them level I have to route the edges to sit level. That worked alright, but never great.

So, after DaddyZ's post the other day, I decided to “re-purpose” my ZCI by adding the option to insert a piece 3/16” hardboard.

It all went pretty straight forward: cut an inch slot with my dado blade, cut hardboard strips to fit, drill screw holes, flush trim with router. The only thing that I don’t like is that the screws stick out of the bottom of the original ZCI, but it really shouldn’t matter in the long run. I just couldn’t find any shorter screws in my collection.

Since I had the tablesaw all setup I decided to cut strips to make 30 inserts. I only drilled and trimmed six of them but I plenty of spares when the need arises.

Thanks for looking!

That is a great idea!
I’m about to embark on a ZCI build(?), for my TS. I was contemplating making several, one for each blade and back ups. This is a much more elegant solution.

Thanks for sharing this in such a timely fashion!!!

I was going to do the same using MDF but maybe I’ll just buy the leecraft one and do this instead to make it more rigid. How did you put the groove in it, router bit or dado?

Also, does your splitter/riving knife go through fine?

Slick idea. This might be a great for Saw Stop saws with their lockdown latch.

Matt, I just used a staked dado set in the tablesaw. I’m sure a router would have worked just as well.

Great idea! I have the same inset on my saw and will do this when it gets too chewed up.

When I have screws project out the other side like that I just use my Dremel tool with a metal cutting disc and shave ‘em off. Then the screws are exactly the perfect length.

I’ve been using 1/2” Baltic Birch for inserts since 1978 when I first started my woodworking business. When the slot for the blade gets a little rugged, I make another new one, using double sided tape, the original plate, a flush trim router, and 1/2” screws screwed in from the underside. I use the worn out one for the next thicker blade. I only use the original metal plate when I’m cutting angles. ........ Jerry (in Tucson)
