Been contemplating the purchase of this type of push block system. I am so tired of replacing homemade one as the get cut up and they are not as safety sturdy as I want. I am asking for recommendations of what model and other info of how many is needed for TS sawing.
I have a question: How can “VERY” thin slices of stock be cut between fence and blade without damaging this push block itself?

I’ve got a pair of Grippers, and like them. They work well. I don’t use them all the time, but when I’m cutting narrower stock, they let me do cuts on the table saw I wouldn’t try otherwise.

If you go to the main Microjig page they have a good photograph showing the thinnest standard part of the block, which is about 1/4” think. Without cutting into the Gripper, that’s the thinnest cut you can make between the blade and the fence. You can certainly run the Gripper into the blade, it won’t hurt the blade, but it will make a cut in the Gripper. You can then use it repeatedly after that to make the same thinner cut.

For a plain pushblock the soft foam grout floats from the hardware store work great.

I have a couple of them, & use them frequently. I bought the optional 1/8” leg, but I think you can get packages now that include it.

Through my own carelessness, I did saw through one of the legs once, but a replacement was easy to order. Better than sawing through my finger!

I’m not sure that is possible, depending on what your definition of “Very” thin might be. “Thin” would have to be at least the width of the push block, to avoid damaging it. But the solution might be to use a thin ripping jig on the other side of the blade? I talking about one of the jigs that attaches to a mitre slot and has a bearing spaced the thickness of the slice from the blade. You do have to move the fence and material after each cut, so that the material butts up against the bearing, but it gives you repeatable thin slices without them being dangerously pinched between blade and fence.

I like mine and use them all the time. Yes, if you are not careful you will cut into it. I think they are much better than a push stick.

I have a gripper with the 1/8” leg and love it but for very thin repeatable slices the jig is the way to go and can be made from scrap. I use mine all the time.

We beat this topic to death last year. As often happens on LJ, it spiraled downward into a useless garbled mess. It did inspire me at the time to do a blog post about my method for cutting the thin strips I turn into chopsticks. My requirement not only involves cutting hundreds of pieces, but they must be very precise down to a few thousandths of an inch.

It’s also MicroJig based, so it’s appropriate for this thread.

Middle of 2017 I went all in and bought the supreme package.
If I were buying today (knowing how I have used the set) I would buy the deluxe package.
I will not use the rip fence without these, that’s how much I like them.
Any push block that is used to make through cuts is going to get chewed up from time to time, that’s just the way it is.

I’m sure its a good tool, but I’ve just never seen the need to spend $50 for a push block.

Why is it cupping? Check your design maybe.

I make mine of a 2×4, drill an angled hole for 1” dowel, and glue on a 1/8” thick shoe.

I make 3 or 4 at a time. When they get chewed up, toss it and grab another.

I figure for 50 bucks I can make enough push blocks to last me another 30 years.

Works for me…................;-)

I have one microjig push block that I received when I purchased my table saw. I prefer using my homemade push sticks because I like having a heel that will ensure the wood cannot slip. I can’t see paying $60 or more for a push stick/block. Just my personal preference.

I know it (the grrrrrrripr) may seem spendy but it’s part of my “no more kickback” regimen. I got hit with 2 kickbacks (in my gut luckily and not my face) in a 2 month period and it scared the s**t out of me. One time I had forgotten to replace the riving knife after using a dado set. Not only am I now SUPER careful and attentive but I went out and bought Jessem Stock Guides. So, when you talk about $ I guess I spent $300 on the grpr and the guides for safety and piece of mind. The wide footprint of the grpr and the drop down foot are very comforting as I reach over the blade to complete the cut. It also insures that I can keep the stock tight against the fence. I know people say they never use a knife and I see vids that make me cringe with folks cutting 3” wide boards with no push stick but to each his own. It just takes so long for fingers to grow back.

I received one for Christmas this year along with a new Shark Guard. Looking forward to using both.
