Merry Christmas everyone,

Hope all are doing well. I've recently taken up pen turning as a hobby while my wife is deployed to Afghanistan. I love the idea of casting blanks, but I'm looking for a way to do it small scale and on a budget.

I'm thinking it might be possible to get a hand pump pressure pot in like 2 gallon variety? Anyone know of any such thing?

Thanks!

Anything capable of the needed pressure will work if it can apply the pressure fast enough, otherwise the resin will set before pressure is reached.

Two gallons of volume with most hand pumps I'm familiar with would take some very vigorous pumping to do that.

Used smaller air compressors are usually findable fairly inexpensively, the pressure pot not so easily found. (At least in my experience)
 
Grizzly makes a good one for about $95...I don't trust the HF ones although some swear by them. Craigs list in the mean time and thank your wife for her service!
 
Josh,
I want to extend a thank you to you and your wife for ya'll service....I was patient and checked craigslist daily and kept a Franklin rat holed. finally it came to be and i picked up a very nice older craftsman for 90 bucks. once again thank you and a very merry Christmas

I have caught a couple great deals on eBay for older used American made pots. I would keep my eye on there as well as CL. Like the others thank you and your wife for your sacrificial service. Been there and done that for 25 years. Lots of separations so I understand.
 
Hi Josh:
If you watch the Chinese tool sale catalogs, you can usually buy a mini "pancake type" compressor for under $40. THEN, you can usually find a 20 percent off coupon to these cheap tool stores. That puts you into a tiny little compressor that will adequately fill a 2 1/2 gallon pressure vessel for about $32.

IMHO, using the cheap tool company's pressure pot (made to no particular standards) is equalivent to buying a $5 motorcycle helmet. About the best you can hope for is to blow your head off

I think a better course for the pot is to constantly monitor eBay and Craig's List for a Binks or Divillbus pressure pot. These pots ARE made to engineering standards and are CONSISTANTLY reliable.

I bought my Binks pot off Craig's List for $40. Additionally, check all the local pawn shops for quality paint pots. The economy has been SO bad for the construction trades AND pawn brokers that here, the price at the pawn shop is VERY NEGOTIABLE !

Respectfully submitted. And thanks to both of you for your service.

Another solution for pressurizing a pot is a "jump start" charger pack, with the built in tire inflator pump. It WILL produce enough pressure, fast enough to pressurize a pot to 40 PSI (all the pressure you really need for most PR casting applications).

UNFORTUNATELY, by the time you buy all of the brass fittings to get the "jump pack s" Schrader valve configuration to the pot connections, you can buy the cheap pancake compressor for about the same dollars.
 
Awesome suggestions. I defiantly am watching Craigs list - so far I've missed some deals worth crying over.


Dude was selling a full set of his father's lie-Nielsen planes for 150$.

Then there was the 50$ delta table saw yesterday...
