dev it's a great deal with you need and can use it ? if not you wasted your money ?

I’ve been wanting a set of these for a long time.

They can be useful (I have the cookie-only set), but certainly easy to fabricate and save some cash. You still got a decent discount and now you have them when the need arises 👍

I went back and forth on them for a week. This is what made me pull the trigger:

Benches are made of wood.

When you bring a piece of wood to another piece of wood, they slide.

This is why we have bench dogs, planing stops, vises, etc.

You don’t always need the staying power of the Hoover Dam, sometimes something with as little holding power as a rubber drawer liner is what you need. So why not just use some cheap drawer liner to interface between the two?

Well, in my experience, drawer liner requires a clear surface. Sometimes there is crap on my bench (by crap, I mean another project). How nice would it be to instead throw down some grippy hockey pucks so that I don’t have to move everything, or at least I have to move very little, because 4 hockey pucks take up less room than a long and wide drawer liner.

I have literally used drawer liner to plane before. I mean, it’s common sense, take a quarter sheet of plywood, slap it atop some horses, no need for a planing stop because there are no dog holes. Slap down some drawer liner, and the pressure of the plane is down and forward, and the downward force keeps the wood you are planing pressed into the liner.

I don’t think I will be planing atop the cookies, unless they prove exceptionally grippy. I got to feel a bench cookie when I was at a friends shop, and I don’t think they are up for that, but sanding, sure. Maybe even some light cabinet scraping. I will have to see.

I do know that for wood finishing they will come in handy. They ought to also motivate me to think about putting some T-track into my future bench.

I use the drawer liner all the time as a sanding surface between the TS top and project. Works perfectly. The cookies also work well and I have the same issues with a pile of "stuff" making for a clear area to sand in rare. Going vertical above the fray with the cookies is one great use.
With the kit you have, the finish pyramids are also handy. Do the inside of whatever (part that will not be seen), flip even when wet and finish the presentation side then let dry. No waiting!

I’ve got a bunch of bench cookies, including the risers for t-track. When I use them, they work great. They’re nice to use as cribbing under uneven pieces to keep them flat, and on larger pieces I’ve used them to raise the whole thing off the bench to work in low edges when sanding or cleaning up. Like I said, when they’re used they’re great. I bought them on a whim was I was just getting into woodworking and thought they would be a super-tool. Eh. Not so much, but I’m not gonna get rid of them.

I would not use them under a piece while finishing. You’ll end up getting finish on them and they won’t be tacky anymore. Get some finishing pyramids instead. I’ve got both pyramids and linear ones (so you don’t get point loads like with pyramids). In fairness, I bought the ones that clip on top of the bench cookies (since I already had them) but don’t usually use the bench cookies underneath! 

Regardless, you got a deal on them and they don’t take up much room so…

yeah ive got the cookies only and thought the same as ryan, ive rarely used em. i use drawer liner though all the time, especially for sanding.

They make for nice dog chew toys (if you leave them within reach) 
Just like with the Gripper though, gotta keep that surface dust free or they'll slide around.
I agree about not using them if you have a brush on finish or something drippy. I use pyramids for sprayed stuff, let it flash, then flip and do the next side.

I think the points will be replacing these horrible things. They are too pointy and they left marks on Black Walnut (not a soft wood per-se). The tips on the Rockler points look rounded and ought not to create little divots

Yeah, I'd avoid any of the pyramid doodads for pressure operations (sanding, etc.).
Some 120 grit will fix the problems with those tips!

Good point!

I like the pyramids (and the linear ones) that fit on the cookies.  I use those a lot.  As I reflect, I rarely just use the cookies.
