In this video I explore the brand new modular vacuum work holding solution called AirWeights! Air Weights are an affordable Hobby and Pro CNC vacuum clamp table. The kit comes with everything you need to get started!

You can probably get somewhere between 10 and 12 psi vacuum. If your board was 20" x 20", then your Z force would be between 4, 000 and 4, 800 lbs. Lateral forces are a function of the normal force times the coefficient of friction. But even with a low friction number you will still get a large enough lateral force to hold almost anything unless you get a leak in your vacuum.

I'm planning to add one of these to my OneFinity X50 Woodworker. With the gasket options from AllstarCNC you can do a lot of different things.

Just an FYI, you have less than 3 months to clean your shop before we come visit. Better start now :P

That was Fantastic!!! 👏 No doubt about it you win the prize for best add yet! I love the review!

@HamiltonDilbeck,
Your router forces are not pulling upward on your material.
Where ever one gets in trouble is the sideways/lateral force.
Try the same experiment by mounting the airweights vertical.
Then hang your weights from the bolt to get more of an accurate account of whats happening.
I enjoy and find your very helpful - especially the vids about your craft shows
Keep the great information coming.

edited - and @KOWspazed info about the psi is great info!

@HamiltonDilbeck, this was a great video. Enough information and a lot of fun. You sure have gone far, now you became a science man 😄.

Thank you for the video and have a merry Christmas and a prosperous new year. Family time!

As always, love the videos. If and when I figure out more to do with my Onefinity, I will probably have to get an airweight. I just experience my last two projects not holding with the clamps and almost causing a ruined project. Thankfully the 2nd project was a practice run, but having them move really sucks. Thanks again for all you do to help us poor slow learning bunch of CNC want to be'ers.

That’s pretty cool! Awesome show of the strength!😁

[RBallarddesigns]

Great job Hamilton! Pretty wild how much it was holding.

That is an amazing setup, and it seems pretty simple to use. You should get a board you can hang onto and a scale to stand on, see how much of your own weight it can lift. No chance of it falling onto your head unless you pull really really fast.

Oh and add the weight of the board!

Very cool, nice seeing a package like this. You might want to consider a hardhat.

That was NUTZ!!! Impressive science experiment at the end.

Hello. Great video. Looking to buy one starter kit.
I cut lots of acrylic small parts 2”x 23.215 long will this unit work. Will need to put mdf on top and skim both sides for the air to flow.
I’m tired of wasting $ on double sided tape. Please let me know what you think thanks

[mpakirk]

@Hamilton If you plane the top and bottom layer of a piece of mdf, the vacuum will pass through the mdf and will hold your piece. And you have your spoilboard in place.

Awesome sauce! If I were doing this as a business instead of an "old man hobby" I would definitely look into this. Since I give all my stuff away to friends and acquaintances can't really justify the cost. But HOLY COW Batman! that thing looks freakishly amazing.

[rivalskygames]

I'm curious about the maths of this, how would we calculate its holding power when changing the size of material used? and is the side pressure from tool movement a factor that would mean its holding power is less in practice?

[andrhamm]

Ooo I’ve been really wanting something like this for use with my Shaper Origin… I don’t use it as much as I want to because it’s kind of fiddly trying to get the shaper tape on the same plane as the workpiece while also keeping everything from moving around

[sd]

How do you do a profile cut into that without ruining that 1000 dollar piece of plastic? Wouldn't that sacrificial board that is sold separately need to have holes in it to transfer the vacuum to that too? It would have been nice to see some CNC examples running that using the profile toolpath

[Ratheon]

I would be more interested in knowing what the sheer force holding capabilities are. Would vibration from cutting and lateral forces combined be enough to overcome the holding force? Probably not, but that would be a more fitting test.

[paulsmessyworkshop]

Ham, I really enjoyed your highly scientific test…WOW!! Impressive for sure.

WIshed it has 32x32 for OneFinity size. I'm looking to replace my wasteboard on my custom Onefinity CNC table.
