I bought a vacuum system for composite parts construction a couple years ago, used it twice and it's been sitting ever since. Here's a link to one for sale through Amazon so you can see the specs:
https://www.amazon.com/dp/B000LBBJGM/?tag=skimlinks_replacement-20
There's no for picture for mine, and I don't have a camera right now
but the pump looks like these.

The pump and a switch have been bolted to a fiber board base so it's
very stable. It has the inlet hose with fittings. It came with a bunch
of breather and release fabric. The pump is in perfect shape, the
cloths have been sitting folded all this time and are kind of creased,
but usable. I paid $150 plus shipping. It has the necessary vaccuum
hose and attachment for bagging.

I've added to it shrink tube: 8 meters of 1", 3 meters of 1.5", plus a
bunch of various small (1/2" to 1/4") sizes in meter lengths. I'll
throw in a sheet of medium glass cloth, about a square yard of some very
thin random weave kevlar, a yard of 1.5" kevlar sleeve and some pieces of
broad weave CF cloth. Also, six 50cc syringes for epoxy mixing,
application and storage. And some helpful miscellaneous doodads,
escpecially a box of latex gloves. These additional materials ran a
bit over $50

What you'll need:
1. Aircraft epoxy (I've tested lots, and use the Premium No Blush at

\
7912592.26185&user-id=&password=&exchange=&exact_match=exact
2. Course through super-fine sandpaper suitable for wet sanding
3. Polyurethane or other suitable coating, plus brushes (foam work
best). Spray on works well, but costs three times as much.
4. SuprFil or other filler/epoxy if desired.
5. Instructions, as found of AeroSleeve or other sources around the
net (someone sells some videotapes?). Of course there's also the
Composite Rockets group here on Yahoo. Plus, if you hook up with a
source of replenishing materials, chance are they'd be happy to advise
you.

Last check on eBay etc. showed the pump alone (no base. wiring, switch
etc.) to run $75 to $100 new. I've got a bit over $200 into this, and it
can make a bunch of rocket parts with only a few supplies needing replenishing
from time to time.

Price, $99.95 plus shipping from Dallas. Money order (preferred) or personal check
(requires clearing time). Sorry, no PayPal or reserves. Be aware shipping isn't
cheap because this thing is heavy. IIRC, it was about $25 when I got it via UPS, but that also included a 4" dual-deploy V2 (already built) and some other stuff. I'll use your choice of shipping methods and get an estimate from that.

Also, bulk Estes A abd B motors
25 of A8-3
31 of A8-5
13 of B4-4
6 of B6-4,
more than 75 igniters,
and pack of wadding for tamping in igniters.
Plus appx. 1 gallon dog barf recovery wadding.
Price $75.00 plus shipping (USPS, shouldn't be more than $5).
That's $1 per motor. Typical price for 24 bulk of A8-x is $2 per.

Pruned this thread because some posts went against guidelines. Please PM me if you have any questions.
Thanks

With Fred's permission to continue....

I'm well aware of the laws. I know them as well as anyone. I happen to know someone who works someplace that ships them and has the proper permit to do so, and he can ship them for me.

And please mind your manners. There's no reason good enough to be filling up TRF with flamage. If someone is wrong, let them be wrong, and move on. You won't change their mind and it's hopeless to try.


Now.... the pump is sold. The motors remain.

Price reduction: $75 shipping included. Money order mailed to me will get them shipped the same day the MO arrives.
 
Sir,

I am interested in the motors if they are still available. I can get a check out immediately and don't mind waiting for it to clear. Work schedule means that it will take me a bit longer to get a MO but I could do that if you prefer.

Thank You,

John Lee
