That is ingenious. I have an Axiom CNC and picked up the vacuum pad system they offer. It hooks up to a compressor, and has a venturi valve...It is absolute garbage, it simply would not hold much at all. Your simple system would be perfect for making a full size vacuum bed for my CNC instead of buying those $3000 vacuum beds....good stuff sir. thank you for taking the time to share this.
I use a dowel drilling jig, instead of the lathe. My vacuum pump is oiliess, so no oil mist in the air. I used my cnc a year ago to make vacuum pads out of pvc, hdpe and baltic birch. Take a 1/4" round nose bit and carve a 3/16" deep square or rectangular or circular or any shape groove into your pad material. Go buy 1/4" diameter foam backer rod from the window area of your hardware store, and put it into the groove. Attach your hose, turn on the pump, and voila.
Great job! I think to ice the cake a set of standoffs near center and the 4 corners inside the rubber strip would allow the object being held to be vacuumed down, while at the same time, maintaining perfect levelness.
@@PawPawsWorkShop I made mine with 6mm EPDM rubber. I carved a groove and placed the rubber in it. It works perfect. I use a Vevor 1hp vacuum pump. When I want to carve acrylic I first put a sheet of 9mm mdf on the pad, Then I put the acrylic on top of the mdf. Works great for me.
You need a filter of some kind as sawdust can destroy the pump over time. I use my setup to pull water out of my 3d printer filement. I got a 15 micron fuel/water separator with filter and a cheeper 12v fuel pump. Cleaned a plastic candy container that holds about 1.5 quarts. Run a hose from the bottom of container through the lid to the fuel pump, to the input of the filter, then out back through the lid about 2 inches. It filters the oil so I don't have to keep buying new oil at every oil change. They do a similar process with food freeze dryers as some use vacuum pumps that use oil also
Your design works very well. However, I think you could get the same effect without having to fling the board around in the lathe. Just drill your initial hole a few inches in from the edge of the board. Then, I think one could just use a hand held drill to come in from the side. If it was desirable to be able to gang the pads together, a router could be used to dig a channel across the pad to a hole on the other side, a couple of inches in. One other idea might be useful to clamp thinner stock. Just run a couple of pieces of the gasket material radiating out from the middle of the pad to keep the stock from becoming concave under the vacuum. Just my 2 cents, thanks.
Have a similar vacuum, what size fitting did you use to hook a hose to it?. The thread size on mine is a weird size and have had difficulty finding anything to be able to hook my hose up.
Thanks for the video. I have the same unit. Any idea what type of oil it uses? "HFV 32" ? Having trouble locating some. Also, after a few months of occasional use, might have a leak somewhere.
This will be a game changer. Could you make templates on the cnc that I could use say on my router table? Ie snack board for cheese ànd meats in the shape of a football helmet ie for the bug game?
Hi, on my barometer it says to "cut top of cap". So it seems like I should cut the black elastic tip off of the cap. I didn't see you do this. Why would I have to do this?
Remember on the Germans original design the ear Inlet was towards the front of the motor and not towards the rear. This would mean that as it's flying an increasing speed more and more air will get pushed through the valve. I would increase the inlet size to scoop and pressurize the air going into the Tesla valve. It just seems logical.. I've done R&D for the greater part of my adult life and was forced into retirement but I still live and breathe R&D. Good luck bro.
@@viisteist1363 Robinair never listed viscosity due to proprietary blend. I used it in my vacuum pumps running continuously for up to 24 hours doing large refrigeration systems. I did low temp refrigeration service for 28 years. Harvest right has it listed in their recommended brands. JB black gold is another good oil.

This is a awesome solution for a vaccum pad. I made one from pvc board and it works fantastic.

Thank you much!! Pot size?
Pressure ratio to spot size? Knowing that has held me from moving forward. Many thanks!
The pot is a one gallon. Thank you for watching
I think I would put some kind of filter. Between the pad and the pump. To keep any Sawdust from going into the pump .
Great idea

im very interested in this new build...looking forward to all of your new uses for this vac hold down.
Thank you very much
thanks very much did the software come with the vevor vacuum
There is no software for the vacuum pump

Excellent idea however, I wanted simple to the extreme. Using the lathe was safe for me while I understand some may not feel comfortable
Great use of the lathe to drill the holes! I have an old vacuum pump (it was my father's) tha I really need to get set up.
Thanks, you should do it. Thanks for watching
Very helpful. thanks I’m thinking about ordering this from Amazon specifically for resin casting.
Excellent. It works great for making the silicone molds and for resins with long working times
That is really great. Thanks for sharing.
Your very welcome
Nice! I'm curious as to your review of that TEVOR pump after 10 months.
Still working great. Have not had any issues
I've always been a fan of Paw Paws Workshop and this is another example of why. Thank you sir for all your inspiration. Tim J Taylor
Thank you so very much. I really appreciate your support. Please share in order that I may continue to grow. Thank you my friend
You are very smart, in comparison to the rest of the world!
Thank you for such a kind compliment. Thank you for watching my videos.

Where does the exhaust goes out from the pump? Do you have to release the red cap?
It just vents into the shop
Would it be possible to incorporate the manifold into your vacuum pad system so that you didn’t need to run the vacuum pump the whole time?
Maybe, I’ll have to try that.
@@PawPawsWorkShop I’ll look forward to an update video
This will be a game changer. Could you make templates on the cnc that I could use say on my router table? Ie snack board for cheese ànd meats in the shape of a football helmet ie for the bug game?
Yes, that is a simple and easy process. In fact you can cut the entire project on the CNC and skip to router
Hi, on my barometer it says to "cut top of cap". So it seems like I should cut the black elastic tip off of the cap. I didn't see you do this. Why would I have to do this?
You may want to consider putting in an inline filter so you don't get sawdust in your oil for your vacuum pump. Great idea though
Thank you, good idea

And also putting oil into the blue cap made my pump sound like it was drowning and didn't show up on the veiwng window.
does it say in the manual which oil u have to use when the supplied 100# oil runs out ?
Any vacuum pump mineral oil specified for vacuum pumps. I've used robinair brand over 20 years and a couple others.
@@1165slugman ok, but is that iso 32, 46 or iso 100?

You're welcome! Thanks for visiting my channel
You have a oil mist exhaust filter so its not coating everything with oil? Ones I have seen cost as much as 2 pumps
What is the largest piece of material that the pad you built will hold safely?
Not sure yet. You saw on the video the only piece that I have carved so far
hii,, can i use single stage vacuum pump for composite bagging?? like same pump u r useing in 2:30
How long have you ran the pump running under load? Do you think a 3 hour cut job on the CNC will work with out killing the pump?
does it automatically shut off when it reaches a certain PSI?
hello sir what is the horsepower of that pump tnx
It is a 1/4 hp
Nice idea.
Thank you
Would this pump work on a work area 15” x 28” ?
Thanks
how bad is the oil exhaust mist?
It’s not bad however it is worse than I expected
Your code has expired on the vacuum chamber just so you know
Thank you. I do not control the codes
The manual was a complete waste of paper if you ask me!
