Hey guys somewhere I saw an aluminum throat place with a replaceable strip of wood for the ZCI.

I’m thinking about getting a phenolic plate and making my own, but If anyone knows where I can get one to fit a Jet Xacta Cut—- many TIA’s!!!

Are you thinking of the Betterly Tru Cut system?

https://betterleytools.com/categories/tru-cut.html

You can buy one, or given a look at the pics of one, they are pretty easy to roll your own. I’d suggest a good quarter sawn piece of wood for the frame, and MDF, or plywood for the insert portion. You can square cut them if screws are used, or make a sliding DT for the insert, and no screws are needed.

The pics at amazon are enough to figure out how they work.

Probably video on You Tube of them too, or better yet someone making one.

I believe you are referring to the betterly tru cut system. I got mine from infinity tools, I have also seen it on Amazon. A little expensive up front but the inserts are only 7 bucks. You can level the throught plate to the saw surface as well as the inserts to the throught plate.

pottz I am probably wrong, but I thought all they had was for a miter saw, and those also are a quick home project, being even more straight forward as the TS versions.

The Betterley tru-cut is nice since you can level the plate and the replaceable insert independently of each other and if you change out the replaceable insert for say a 45 degree cut you don’t need to re-level the insert. Works slick. We used one at the last place I worked. I am hoping they start making one for my saw. For me the $80 they cost hardly seems worth trying to make my own. But I have more money then time these days.

I knew I saw them somewhere

You guys are the best!.

@SteveN I could make one but at this point in my life I’d rather spend my time making something.

Looking at the price of the inserts, I’ll get a couple but I’ll make up a bunch out of wood or see if I can buy a phenolic sheet the right thickness.

I Wish they had one for my other saw it’s a Jet 1 3/4horse.

I like the concept. However, when I built one throat plate, I built ten more. They slip in and out without reaching for a screw driver.

If the Betterly were friction fit and I could drop a piece of 1/4” ply, wood, composite or plastic in, I’d be on it in a heartbeat. I never run my stock plate and always run a zero clearance.

Seems the trade off of having to unscrew one plate to screw in another, then reverse the process is a trade off that would end up in about the same time it takes to use a router and a pattern bit to make several plates for 90’s, 45’s, 22-1/2’s, dados and so on.

LJ Thetinman makes his own for his standard plate. Not the same saw but the same basic idea you were asking about.

I finally found making a Aluminum table saw insert, with replaceable inserts again. http://www.woodcentral.com/articles/shop/articles_893.shtml I also think “Fine Woodworking” had one made from a Sawstop Insert. I myself just got the Infinity one and have had no issues. Dan

What the Betterly offers over Ho made is that even if you say 2010 Unisaw. None of them have exact distances from the top of the ears where the plate rests, and the top surface. Always small variance as they are the nature of “cast” iron. I submit they aren’t huge, but with the Betterly you can address ANY of the innies, and outies you run into.

I’ve long made ZCI’s for a number of different saws, and have seen thousands more that others have made for their saws. Almost all of them move if you push down on a corner. Even the very pricey store bought ones aren’t going to seat perfectly, and they usually offer something in adjustment at the corners. The Betterly is adjustable from all sides, so you can make it fit your saw precisely.

Is that absolutely necessary??? Probably not because a lot of us are making are own, and I haven’t heard of injuries due to that, but they stuff happens.

I’d put Betterly at Saw Stop level expenditure. Do you absolutely need it? Of course not. But from a safety point of view they win. For accuracy, and the precision aspect they kick a lot of butt for the price.

BTW you only adjust the Betterly one time if you use Blue Locktite, and you can make your own wooden inserts, You just need to pattern them from one of theirs so the screw holes are perfect.

Now that I think about it, the plate I’m wondering about had inserts that slid in rather than screwed. Exactly like the one referenced by RDan. Although I’d love to have one exactly like it, I don’t have time/desire for the fabrication,

No big deal but anything that saves time, then again how often would I change them?

Regardless I’ve got one ordered.

That wouldn’t be accurate for mine. They drop in, fit tight and are the same thickness as the depth of the throat. As do a good share of other home-made ones are like mine, I suspect.

Many of mine are composite. Others are plywood.

For many, where the ears are (on which adjustment screws would land), I router them to let the new, uncut throat drop flush.

Using a router to do this was a breeze. All I had to do was set the depth. Then I could mark the spots and freehand the cut, since being over an eighth of an inch hurt nothing.

A few inserts were made from wood I planed to the depth. Another was sanded. In the end, I do just press them in and pull them out.

A few just have small square drive screws that allowed me to level them. Pre-drill four holes, grab a caliper, measure the throat depth, lock it, then, quickly, set the screws for the proper depth. [Never had one fall out of adjustment.]

Of course, all have a hole to allow me to press the button by which the splitter is released, have a slot for the splitter to drop down through and have a hole to lift them out.

Like I said, I made about ten, using a pattern or template bit. About six of them are still virgin, over five years later.

In the end, it may be a bit of the Ford vs Chevy thing, or just boil down to that many like the looks of the Betterly, which I do. However, for now, I like that mine swap far faster than the Betterly, since I just pull the ninety degree zero out and press in an insert for another operation.
