Anyone here built a Vac Generator for a lathe ?
I decided to build a vacuum generator for my lathe. I'll get the Oneway attachment for the hand wheel.
Never having done this before, and never having used a vac on a lathe, how do these spec's look ?
The Air-Vac MFP-M104H 2 stage vacuum motor will create 27.2HG with 6.0 CFM of flow, from 2.4 CFM of compressed air, at 75 PSI.
I have an 80 gallon x 5 hp compressor that is more than capable of keeping up.
The motor is $60.00 USD .. with a $22.00 Muffler.

I figure I would need a vacuum gauge and a regulator .. I could use the regulator to control the whole thing ??
The advantage over a Vac pump would be the 80 Gallon tank on the compressor. In the case of a power outage, or a tripped breaker, I would have plenty of Vacuum left to hold the work until it stopped spinning. And I have the air already..
I also think this would be far more capable than the Holdfast if I wanted to use it for Vacuum bagging, due to the volume of air this will move.
The Holdfast appears to be rated at .6 CFM of flow.. While the Oneway system is 4.5 CFM of flow.
I really think in a lathe situation.. There would be so little flow that the compressor would probably never kick on ..
Where are my flaws in this plan ?
I am thinking of building the whole thing into the lathe, with a coupler to be able to use it for other things.. So the lathe would become the Vacuum pump as well.
