[PSUBS-MAILIST] Psubs Barge

Fri Sep 5 20:26:23 EDT 2014

Cliff,
There are two wing tanks that the crane lifts into place and we bolt them on.  The wing tanks are also 500 gal propane tanks.  The barge could lift the sphere sub (2,400lbs) 6 feet from the deck.  
The crane is off now and a hydraulic winch is built to go in it's place.  
I would donate it to the psub group but shipping is more than it it cost to build.  It is 500 gall propane tanks welded together with used 8in channel that was laying around lol  It is very safe because the tanks are separate.

 That is outrageously
 good, and the cost is crazy low for the result. Plus, I love
 the small items you just happen to have lying around in the
 parts bin. 

 Hank, we should
 all just buy it off you for two grand so you double your
 investment, and we'd still be getting it for a small
 fraction of what it would cost new.

 Best,

 Alec
