I tried posting some photos of this set up but I'm guessing that you can't do that and the original post with the photos is stuck in the filter somewhere in cyberspace. So, if you don't mind I'll list the specifics and if you want photos I can e-mail them to you. Im selling a great vacuum pump set-up for bagging. It includes a used but in excellent condition Gast model DOL 101 - AA pump, manifold, adjustable vacuum pressure valve, new vacuum pressure gauge, exhaust muffler, intake filter and hose barb. This pump pulls 25 hg (at sea level) , which is more than sufficient for any bagging project.It is quiet, capable of handling several bags at one time, runs cool and is designed to operate 24/7.This is the same type of pump that many production shops use. It will likely outlast any one of us so think of it as an heirloom. OK thats hyperbole.Youll need some 3/16 or ¼ vinyl tubing for your vacuum lines. This material is available at home stores and hardware stores for about $.10 per foot. You also need the usual assortment of things like vacuum bags, bag seals, bag hose fittings etc. All these items are available from the Composite Store or Aerospace Composite Material.$180 + $15 shipping anywhere in the lower 48 states.

[RCSE] vacuum pump system for sale
I've been selling vacuum pump set ups to modelers for almost 12 years. This one might be the nicest yet. The system includes a diaphragm pump that is really quiet. The pump has a built in fan for cooling but in addition there is a computer type whisper fan in the enclosure. (Photo available - email request) Everything is contained in a metal cabinet with a carry handle on top, a large 2.5" vacuum gauge that reads from 0 - 30 IN Hg, a vacuum relief valve that makes adjusting vacuum levels from 1" Hg all the up to 20" Hg which is more than sufficient for any bagging process. There is a hose barb on the front panel and an on/off push button switch. These systems sell for over $450 new. This is a unit with very low usage and is very clean. $165 plus $15 for Fedex Ground insured shipping anywhere in the lower 48 states. Ed
[RCSE] Vacuum pump question, how to lube?
Hi all, I have recently received a vacuum pump for bagging stuff to throw at the skies, and it works quite well drawing 26 inches fairly quickly. Before I use it though, I'd like to ask the knowledgeable folks how to lubricate it. It has a bit of a squeal as it runs, and a plate on the back says to lube it every 10 years or so at normal duty. I have no idea how old it is, but the squeal concerns me and I'd like to lube it as a precaution before I start running the poor thing for 12 hours at a stretch. I don't see any lubrication fittings. Any help that could be offered would be very much appreciated, Thanks Dan It's a Will Scientific pump, s/n 67 394473 The motor on it is a GE A-C Motor, 5KH32EG 550T HP - 1/6 rpm - 1750 AMB - 40C V - 115 A - 4.2 CY - 60 Time Rating - CONT. Ser No. - GCD It is thermally protected. RCSE-List facilities provided by Model Airplane News.

I don't see any lubrication fittings. Consult the manufacturer... though I can't find anything on Will Scientific. Is this the full name? Any other info? (City? State?) on the label? Generally pumps that _NEED_ oil have obvious fittings. Pumps that don't _NEED_ oil get the same treatment as any other motorized device: lightly oil all metal-to-metal bearing points (1 drop of light oil per part), wiping away the excess. Don't oil sealed ball-bearing races. Squeaking is bad, not only for the ears but for the life of the device. Use a vacuum resevoir and a vacuum switch to activate the notor so that the motor doesn't have to run continuously. A 5 gallon air tank makes a good vacuum resevoir. Vacuum switches cost about $25 for adjustable mechanical ones, and more for digital ones (I bought two used SMC off EBay for $70). Digital ones are harder to hookup, as it requires some electronics. -- Andrew E. Mileski RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] vacuum pump - air conditioner compressor
Erik Lotoszynski wrote: Will a compressor from an air conditoner draw enough vacuum for bagging? Possibly. People have used old refrigerator compressors http://members.ozemail.com.au/~flyingwing/vacbag/ I think modern refridgerants require higher vacuum than Freon did, so it might work really well. It wouldn't have to be continuous duty if a vacuum switch is used with a narrow deadband. More imporant is the sealing of the bag, and of the pump (I've got a checkvalve on my pump as it leaks) If there are no leaks, deadband doesn't matter. If you have leaks, narrrow deadband is preferable, but can mean more cycling of the pump, which causes reduced motor life. If the run time is too high, you have leaks. If you can't seal the leaks, adding a resevoir helps to decrease the run time. Also, what is the purpose of the reservoir? As Einstein said, Everything's relative. Even when it comes to vacuum and leaks! :) A small leak takes longer to drop the vaccum on a larger volume. A vacuum resevoir increases the volume of the bagging system, so the vacuum pump runs a whole lot initially, but less once the target level of vacuum is reached. Aim for 15 seconds of pump run time every 10 minutes or more if your workshop is within earshot. -- Andrew E. Mileski Ottawa, Canada RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] Vacuum pump
It is probably a "High Vac" pump good to maybe 50 microns vacuum. If the pump looks like a lawnmower engine, then it is. Use a big resevoir, (old propane or freon container) so it will cycle minimally. I have about a half dozen similar at my disposal, never considered throwing any of them out.

Re: [RCSE] Vacuum pump
14.696 inHg = 760 Torr (1 atmosphere - standard pressure) 0.1 mTorr = 14.696/760/1000*0.1 in Hg 0.1 mTorr = 1.9 x 10 ^ -6 inHg (about 2 millionths of an inch of mercury) That should be plenty of vacuum for you.
