Vacuum Pump Built from JUNK

Homemade Vacuum Pump

Another great item built from scrapyard parts or from items on the curbside so that you can keep the money in your own pocket and not give it to the next guy. 

Have you ever thought about doing the work on your automotive air conditioning system youreslf but could not justify spending hundreds of dollars for a vacuum pump to evacuate the system?  Or..... have you purchased one of those cheap venturi style air operated units from Harbor Freight or Ebay and like me and found that it was a piece of JUNK, not able to pull a good vacuum and it took way too much air?

Air Conditioning Vacuum Pump

Well, here is a set of instructions to build your own Vacuum Pump.  

This is a set of plans to build your very own, low cost vacuum pump.  The 14 page manual has step by step instructions and photos on how to build a vacuum pump using parts from an old household appliance.
