So is it safe to say that you have 3" hose running to each inlet on the table? How large are the inlets on the plenum? Also, is it safe to say that the hose going from the pump to the table and all...

I dont understand. The pump is rated at 169 CFM and 24 HG. You mentioned you have 3" hose running to the table. What about under the table. Is it 3" running to every zone outlet? Right now my table...

I am reading a lot about the pipe size under the table. One post says the plumbing diameter should be at least 1 size larger than the inlet on the pump. Another is saying just use 2" on everything....

If I use those then they will leave little holes in my pieces and I cant have that on my final product. Thanks though

I went back out and played with my table more and I got 19 HG with table loaded and 10 when not loaded. The major problem I have is that my HDPE boards have rounded edged so when they are butted up...

Yes I did and there is a lot of flow. Maybe to much. Thats why I am going to add the second layer and see if that helps. When I first fired up my vac with boards on I had 10 HG. Then I started going...

Thanks for the advice. I actually bought the vac last year and right before I did the seller put new vanes in it. Its rated at 24 HG but I am getting 23 HG right at the vac with nothing attached to...

Ok, I swapped out my piping from 1" to 2". I have my dedicated zone hooked straight to my vacuum (Not through the 6 zone manifold) I bought a Trupan Ultra light board (32 lb/ft3). I cut it it half so...

Yes I also feel the vacuum pulling through my current MDF board when I put my palm on it. But its still not pulling through enough. I am getting 17 HG on my table with or without the spoilboard being...

The stuff I am using now is cheap grade stuff and I am not getting any flow through.

Thanks for your help. I will be purchasing a light board tomorrow. I will get back on here and let you know how things go later. Thanks again

I was using Duct tape to seal my edges. What is absolutely the best way to seal the edges?

was the difference you seen from the regular MDF to the ultra light a HUGE difference or just a better? Also I am cutting 3/4" HDPE so I dont know if there are other requirements for hold down force...

gfacer2. I asked them if I could just get them from a buyer and they said probably not because the buyers buy it by the truckload and go through it very quickly for production of furniture

Gerry. I am using Regular MDF right now and I am not getting enough vacuum through it. My gauge is reading 17HG with and without boards covering it up. I believe the regular MDF is to dense to allow...

Great, Thanks for the help. Is it possible to filter or reach people on here that live or work close to me. I found a dealer for Trupan ultra light but they want me to buy 40 sheets at a time which...

Thats not good. another question: If I have a 4 x 8 Spoilboard laid on my CNC table and underneath it I have a 2 x 8 area gasket ed off am I loosing vacuum from the area that is not gasket ed off. Do...

Just so I am reading that correct. If I have good flow through my spoilboard with nothing on it I should be experiencing very little vacuum (somewhere between 0 and 10?) When I put the boards on it I...

How much Vac loss should I be experiencing from boards on and boards off. Are we talking like 1 or 2 HG or 5+?

So I spoke with some distributors of MDF and they told me the density for regular MDF is 45-50. Light is 40-45 and ultra light is 35-40. (Trupan Ultra Light is 32, Best on the market) I cant even...

I bought some normal MDF. I think the density on it is 45-50. I am trying to find Trupan Ultralight right now. Finding out that is it quite hard to get a hold of. If I cant find it what should I use?

My Spoilboard is completly sealed off on all edges. and the Gasket under is zoned off to just where I am cutting. What is normal size piping for under the table. I am wondering if I am loosing some...

I have two questions:

1. Is it possible to locate other people on here that live in my general area (Grand Rapids, MI)?

2. I ask because I am looking to buy bulk Trupan Ultra-Light Boards to...

What about loosing 6 HG from the pump to the table? Why might this be happening?

Disregard

Thanks for the advice. I have tried 6 passes at 200 and 300 ipm and still get pretty bad finish. Thats why I think the machine itself might be the issue. As for the vacuum, I just hooked up a...

I do a total of 3 passes. I do 2 passes at ~.35 on all my pieces first and then run a 3rd pass at .05 "Onion Skin". I cut at 100 IPM which is considered pretty slow compared to what I have heard...

Hello all,

I could not find a forum on here for Vacuum table questions so I am posting here. I own a 5 x 10 Laguna Smart Shop II with a vacuum table powered by a 10 HP Becker pump. 169 CFM, 24 HG....

Thank you for all the advice guys. I really appreciate it. I just ordered a new ISO30 Tool holder, 1/4" Low Helix Upcut spiral bit, collet, and nut. I am going to run all these new parts tomorrow...
