mirror70 Posted July 16, 2004 Report Share Posted July 16, 2004 Within the next week, I'm looking to acquire a pump which can pull at least 24"hg of vacuum. Are there any bombers on here who have an old working pump they want to get rid of? Quote Link to comment Share on other sites More sharing options...

fin Posted July 16, 2004 Report Share Posted July 16, 2004 mirror70, What are you using the pump for? Tell me you are building your own flow bench for testing ported heads? Might be able to help you. Quote Link to comment Share on other sites More sharing options...
mirror70 Posted July 16, 2004 Author Report Share Posted July 16, 2004 I need the pump for vacuum bagging some carbon fiber parts before curing. It doesn't need to flow a whole lot, I think .5cfm would be fine, but it does need to pull at the very least 24"hg and it should be rated for continuous use. Running off of 220V is fine. Do you have anything that fits the bill? Quote Link to comment Share on other sites More sharing options...
fin Posted July 16, 2004 Report Share Posted July 16, 2004 Well, I did have plans to make a flow bench once and what I found out was a large Shop Vac works great. I was told that it should achieve up to 28" no problem. They are relativley cheap and easy to get at you local Home Depot. I bet it would work for vacuum bagging some parts.

D-Sub Posted July 16, 2004 Report Share Posted July 16, 2004 heck I thought it was funny Quote Link to comment Share on other sites More sharing options...
mirror70 Posted July 17, 2004 Author Report Share Posted July 17, 2004 I'm looking for something in the $50 range, so I don't think Home Depot will be of any help. eBay has a few pumps that look like they could work, plus I can always engineer something out of an old AC/refrigerator compressor. The flow bench is going to have to wait until the CF business takes off. Every available dollar (yeah, both of them) is going into it, so I couldn't even afford a spare head so I could drive my car while I work on the über head.

Art Posted July 17, 2004 Report Share Posted July 17, 2004 Check to see if there are any Surpluss shops around. We use suction units to evacuate air ways in the field but im not sure what they would pull. If I remember to bring a guage in I could find out. The Shop Vac thing sounds reasonable and I have seen the small ones on sale for less than 25$. Also, check the local auto supply stores. They have munual kits (hey, there's always the Snap-On guy :D ) on sale. Good luck. Quote Link to comment Share on other sites More sharing options...
UK2TX2CA Posted July 17, 2004 Report Share Posted July 17, 2004 A Mityvac will "generate" 30hg, not sure how much a wine vacuum pump produces ( like the one used in the Roarockit skateboard building kit ).... Quote Link to comment Share on other sites More sharing options...
NateW Posted July 20, 2004 Report Share Posted July 20, 2004 People are trying to sell me these things five or ten times every day. I've been deleting those emails left and right for years, I had no idea they'd be useful for making snowboards too. Quote Link to comment Share on other sites More sharing options...
mirror70 Posted July 20, 2004 Author Report Share Posted July 20, 2004 Nate - you bet they're useful! Most are guaranteed to turn your slalom stick into something more appropriate for Super-G in 30 days or your money back! Quote Link to comment Share on other sites More sharing options...
