Great video. Thank you for sharing your project. Your approach really makes perfect sense. Was wondering if you have any trouble with heat dissipation from the vacuum motors?
Do you have a parts list or some drawings of your setup? Really enjoyed the video and would like to interpret this into my design. Also, do you have specs and design plans for your cnc it's self? Seems well constructed and simple enough.
Put a hood over your motor inverter. One metal flake in the top vent and POOF! Speaking from experience. Four seems way overkill. How many do you usually run?
When reviewing the spec sheet for the 122178-18 it specifies that the cooling intake, cooling exhaust, and vacuum exhaust should be separate (Page 2, Notes 5 & 6). It doesn't look as if yours are separated after reviewing the video, have you had any issues with over heating? Any thing you would change in regards to the vacuum system in hind sight?
Great video! I'm building something similar, but with only two motors. If I'm always going to have the two motors on, are the guillotine valves necessary right after the box? I was going to Have the two motors combine into a 3" manifold, then use the guillotines instead of ball valves to open the two zones I will have. And are the 3" rubber couplers used for a reason, instead of simply gluing the 3" sweep wye fittings into the guillotines? Vibration reduction? Thanks for the help!
Was about as loud as my dust collector. I am building a baffle that all four will feed into. The guy that sold me the motors gave me the plans. Very simple.
I don't understand why you have four vac motors when they all connect to a common pipe. Wouldn't one do the job seeing you have the stiff red valves. I plan on using PVC sheet for the grooved panel so I don't have any worries about air leakage. Also using PVC sheet with holes for the spoil board. Have you experienced VTO (Vertical take off) when all the motors are running?
Thank you for making this video. Im building my vacuum table based off your information. One question I have is: Do you still feel the 4 motors are necessary? I have bought 3 so far and will get the 4th if you think it helps the system. Just curious, thank you for your time.
Contrary to common assumption, you actually need a Denser board for good vacuum. Now I don't know if that holds true to less powerful vacuum systems like the one in the video but MDF instead of LDF should be used. Denser board distributes the vacuum better.
@@haydenhandiworks8157 That's good to know. It seems like that makes sense actually. Our Becker 15 Hp VTLF pump likely is where we see the difference in vacuum. I can see the smaller pumps benefiting more because they're less able to pull air through dense board. Not sure if that's how it is, but thanks for sharing. I can't afford a 15 thousand dollar pump like my company so I may build one like yours.
Bravo! Just great information and without horrible music. Thanks so much!
Finally a detailed video about a vacuum table. Thanks
Super inspiring! Thanks for taking the time to make this video! 🙂

Amazing product
I know it's been a few years, but you wouldn't happen to have a copy of the plans for baffling the exhausts do you?

Angle of the V-bit?
Interesting build thankyou for posting, can you please tell me how noisy the system is?

@@haydenhandiworks8157 Thanks for your reply, I would be interested to know how the baffle works out for you
thx for your information sharing.
you put 4 vacuum motor on your machine, how much every motor has power?
Are those brushless vacuums motors?
If its brushed motors, what is the life expectancy of the motors before replacing the brushes or the entire motor?
Do you know ware I can get the motors or the motors specs thanks.

Do you have any links to the places you got information on performance. I am building a 4x8 table and really want to get a good plenum built for it.
Are there any
air filters?

Can you post a link to the switches? I have seen other people use contactors.
How many amps is each motor pulling? Sorry if I missed it, are they 110v or 220v?

Well done, very informative!!!
Where do you find Hdf
Local wholesaler. Was in stock. I think cabinet guys use it for counter tops. Mine was 5x10
Anyone know the angle of the v-bit?
I was wondering if you ever got an answer to this? I'm trying to improve my vacuum table. thanks.
Contrary to common assumption, you actually need a Denser board for good vacuum. Now I don't know if that holds true to less powerful vacuum systems like the one in the video but MDF instead of LDF should be used. Denser board distributes the vacuum better.
Thanks for your comment. I tried both and the LDF was far superior to holding parts than the MDF. My vacuum on the gauge pulls 7-9.

Thanks so much for the informative video! About how large is your grid? Like how big are the little squares? 1.5"?
