I think I am interested in a vacuum pump for my Powermatic lathe.
I know of the advantages and that's about it. Oh, and continuous run pumps are better. Where do I get good information? Obviously building your own saves $$$. Do the pumps with the "vacuum pots" work for lathes? As you can see, I have lots of questions.

Joe Woodworker has a good reputation. I would not hesitate to buy from him.
I am having a senior moment about the name of the last person I picked up a vac kit with a pump. Something like "Stingy Woodworker." When I find the name, I will update.
There used to be someone who would sell refurbished vacuum pumps in SnS. It might be worth posting a WTB there.
For turning, the venturi-effect vacuum pumps work well if you have a good air compressor. They are not really suited for vacuum bags, though.
Having the proper valves and a vacuum gauge for the manifold are obvious basics. It is a good idea to add a phase separator filter to keep abrasive dust out of the pump in case you make a funnel while using a vacuum chuck.
Update: I think that the person that I got the kit from was Frugal Vacuum Chuck.
I dealt with them at one of the AAW symposia.

I recommend a vacuum pump, not a dust collector Venturi type or an air compressor Venturi type. Just my opinion...
I got lucky and found 1 on Craigslist. It was on a big piece of medical equipment. Not as deep a vacuum as an HVAC pump, but close enough for me. I haven't had a workpiece fly away.
Look for a used one. I wouldn't be afraid of buying it from Harbor Freight.
If you get an HVAC pump, you should think about adding a vent valve, very thin pieces might crack from a deep vacuum.
I haven't bought from here yet, but it all looks good to me. Rubber Chucky
