I found a diaphragm vacuum pump for 125$ on Kijiji. Guy in Sherwood park AB.. Is it a good deal? And how well would it be for rigging up a stabilizing system? Dan, I know you'll have some good insight lol
Ya that guy lives by my place. He has a ton of stuff for sale. 22" hg vacuum is okay, but more is better. I was able to pull a little more than 25" hg with a good ole hand operated brake bleeder from Princess Auto. Ok, my arm was like Popeye for a while but once the bubbles stop, it's done. An HVAC tech friend was suggesting an A/C service vacuum pump. A little more money, but in the future you can sell it for good coin if you wanted to unload it. Dan
Yeah I was a hand pump, but I wanted to get something more..suiting. Something that I can turn on, monitor, and do other things to make better use of my "knife time". Im pretty sure you can turn them up, 22Hg is just the operating pressure. I went ahead and ordered it. I'm sure I can turn it over if I don't like it. Worst case it doesn't work, but I think it'll do. Fingers crossed
I bought a new 3cfm MasterCool AC vacuum pump from PartSource to make my setup. It cost $135 or $150. Brings me down to 28 Hg super quick. I put in a bypass valve on the line out to take the pressure off the pump when its not running. http://www.mastercool.com/product/90062-a-3-cfm-vacuum-pump-single-stage/
was researching wood stabilizing and looking for something other than the hobby type that seemed most common and found this site offering a wide assortment of vessel sizes and pumps. http://www.bestvaluevacs.com/glassvac.html they only warranty the glassvac series for stabilizing resins
John If you need a vacuum pump I have one that was donated to me from a buddy in the junk business. Its from a hospital. If your interested and your coming to Wpg in the near future its yours for the cost of 1 large Timmy's coffee. I already have a couple so I don't need another. ( I just can't stop bringing stuff home when its free though) PM me with your phone number and we can set something up. I have free long distance... Frank
A old blood sucking machine that should be perfect. I get into Winnipeg quarterly usually but something might come up sooner.
I built mine with a diaphragm pump and a glass vase from Micheals.. Holds roughly at 24-25in/mercy works grear
After building the BG-272 Grinder (great plans Dan!) my next venture is a vacuum chamber. I see lots of talk about the usual vacuum pumps but what about a vacuum generator? Does anyone have any experience with these? http://www.air-vac-store.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=AS&Category_Code=AVR
I think this is what Stick Fast uses in their demonstration video. I have one that uses 4.5 CFM at 90 PSI which will keep most compressors running continuously. Works good though, around 27 inches Hg. I got mine from Amazon.ca. https://www.amazon.ca/Advanced-Design-ATD-3410-Operated-Vacuum/dp/B000M5ZVRK Certainly beats the brake line vacuum pump and associated Popeye forearms. Dan
Gregg Distributors has the same style made by Air-Vac. I don't have a price for it yet. Thanks Dan. I have a compressor at home that will deliver the air but just barely. My thinking is that since the resin will bubble up and the vacuum will need to be limited at times, the compressor won't need to run constantly until it gets near the end of the process. Is that accurate? And did you use your vacuum generator with the pickle jar arrangement? Martin
If you connect a ball valve, this will let you control and preserve the vacuum. The effect of the vacuum is most noticeable when you start. A whole pile of bubbles come out of the wood, so you have to moderate the vacuum in the beginning. After a few minutes you can ramp it up (down?) to keep pulling air out, but the rate of change of vacuum will get less and less. With the pickle jar I have the hand pump and the venturi vacuum pump.
