I recently posted some questions on vacuum chucks and was glad to get
all the responses.

I have decided to purchase a vacuum pump and would appreciate some
answers. I have been looking on E-bay where there are lots of pumps
listed for sale but I seem to only get more confused with all the
options available.

What Horsepower pump is needed? I see pumps from 1/6 to 1/2 h.p.

# of Cfm's needed? See 1 to 7 cfm

one or two stage pump?

Oil or oilless?

How much vacuum is needed? I see pumps from 20 to 26
