Vacuum pumps

[Sparkey]

Decided I wanted to add a vacuum pump to the shop, so I ripped apart the vacuum sealer I got at Goodwill for $8. (Odd how we have so many of those in the second hand stores here in Eugene ). If I'd had a little Phillips head screwdriver, it looks like I could've popped the rubber feet off and taken the screws out, rather than damaging the plastic case.

So now I've got this vacuum pump with a red and black wire coming off of it. Black is negative/red positive? Does that correlate with the larger blade of the plug?

Coincidentally, this unit never vacuumed, only sealed, so if the pump doesn't work I'm gonna go shopping for another one.

So I hooked the black up to the larger blade on the cord, and the red to the smaller....it lit on fire. Looks like it is a DC pump and there is a AC to DC converter - the little black box - on the circuit board, which is why it got toasted. 10A 28VDC wall adapter? Do they make such a beast?

$8 well spent on tuition, I'm gonna go look for another one tomorrow.

What are you using it for? Vac stacks?

[Pogo]

I use a coleman air mattress pump for vac sleeving everything..... works great, and if you get the one that runs on 4 "D" batteries you can vac sleeve at demos or friend's studios......

$0.02

Sparkey plays with electricity!

You answered most of your own questions.. but..

The vaccum sealing pump is terribly slow, I wouldn't suggest it for vac stacks.
that hand pump ... I doubt I suggest that either.. but youhavent said what you are doing withthe vacuum yet.

This one, or its companion, is what we use, and was recommended to us. Keep an eye on the price, or coupons, we got ours for $70. Soooooo much quieter than a shop vac. Leave a pinhole leak while using it..

The currrrrsed double post.. hi

I just stick a rubber cork in the end that has a hole for my blow hose and another vent hole so you don't burn out your shop vac. Don't overt think it. Unless you Are using it for a vac plate to do Stump/Stankard/Tribucco type encasements.

shop vac

we just stick a cork in the end of the shop vac with a 9mm blowtube attached to a hose a that connects to your stack( make sure its connected to the proper side) you'll need a swivel. go slow with the melt-in making sure there are no air pockets under color rods. easy as pie

I wouldn't want to use 9mm for a vac stack personally, but to each his own.

Yeah, I throw a 25x4 on each side - it adds weight, but makes melting in the ends way easier. But it seems at least 12mm would be wise.

Get the Coleman pump Pogo mentioned. They're under 30 bucks (batteries usually NOT included) and work great.

coo the search page ,lol

[ALIEN!]

fuck that, keep trolling craigslist or ebay for a used Gast pump, I see them go for around $40-60 all the time, well worth it, wont go fuckin deaf either. I got mine out of an old automotive diagnostic machine, but really, fuck all that racket from a shop vac or getting tennis elbow trying to use a dick pump. Plus a solid Gast (or similar) pump will LAST.
