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?
