9"--by the time you lose some to leakage you could be in trouble with small bowls.

the guage reads cm hg. i guess it might be from accross the pond. medical equipment. i set it up good. no leekage. get the same reading hooked to the lathe as i do not hooked up. this thing came with a glass bottle with stopper i did away with the bottle and used the stopper to make my conection to the lathe and siliconed all of it. I have not made the vacume chuck yet though so i will probly get some leekage there. it has a bleeder built in so I can turn it down some but i may not have to use it if there isnt enough suction to start with. any way to soup it up? lol... did i mention it was FREE? if it works its a gloat if not i'll write from the ER.

It's not just the pressure you need to worry about it's the volume of air the pump can handle to overcome leaks. If you're only turning sound wood with no cracks and no leaks, good seals, it should plenty strong, but if you have any leaks at all.

FYI if you want someone to help you with a product, put on the model number, not the serial number (is it model 102, 120, 130, 136, 230 or

330?), and spell the name correctly. Is this the pump? If it's a suction pump for medical waste, it might work fine, since it's designed to suck out material. Your best answer will come from the manufacturer, who will be able to tell you how much flow it can pull and maintain pressure.

It's about 4 1/4 psi, which on a 2" diameter is only about 13 lb force.

by the way i did get the faceplate made today. to test it i placed a glass bowl on the face plate and fired it up. i could not pull it loose so then i stood to the side and turned the lathe on slowest speed. im still alive and the bowl still holds soup sooo............. this was my first experiance with vacume anything. i like it!!! im probly only going to use it for sanding and finishing the bottom of small bowls. i dont think i will be trying to do any cutting with it. thanks,

it looks like your questions have been answered. If it holds wood well enough for you to do what you need to do, then you got a good deal. there is my "booklet" on vac chucking which you can find on my web site,

- it will give you a table of holding forces versus the amount of vacuum.
