I just picked up a hand-operated brake bleeder vacuum pump yesterday from Harbor Freight for $18 with a coupon from the newspaper (could probably be found online as well). I plugged the line and pulled vacuum this morning to test it. I was able to get 20" Hg and four hours later it's still sitting at 20" Hg. As long as you can make sure your vacuum bag is well sealed this seems like a pretty good inexpensive option.

I show how to use that in my videos. One BIG suggestion for you; Once your bag is sealed up first pull the air out with a vacuum cleaner, then go to the hand pump. if you try to pull all the air out with the hand pump soon you will have forearms bigger than a Gorilla!

My arms have gone back to the original size now.

Thanks for that tip. What do you use to seal your bags? I imagine the bag clips don't seal well enough for a hand pump, but the gray bag sealer tape (we call it "elephant snot" at work ) is a real pain to work with.

I use the bag clips but double the bag into the clip. Normally I have to come back every hour or so and give a few pumps to bring the pressure back up.

Why not post here?
This is where you started. Or should we unsub this thread and go over to your DLG thread?

In your hands...............so to speak.

Hi Jim, I started this thread for cheap vacuum pump options. I just thought you might like to see my DLG build using this pump.

For sure! I'll get to look at it as soon as I have the time.
I also have ambitions of one day building a DLG. So, need lots of education in that regard.

Err, I wouldn't use me as a refrance except maybe to see what not to do. This is my first build since I was a kid. It's kind of off the kuff.

Dani,
How do you attach your handpump to the vac storage bags? Do you attach via the existing fitting or do you add an additional one?
