<DIV class=yiv4493150183y_msg_container>Hytorc makes a good line of robust,
self-contained continuous duty pumps, most adjustable from 1500 to 10000
psi. The.120 volt units we used had a universal motor so could be run on
straight off the main buss. We set them up with an accumulator pre- charged
to 1000 psi and a pressure switch set 1000 to 1500 psi. This supplied
pressure to a double bank (6 each) of Parker-Hannifen solenoids controlled
with their own 12 volt tap. Twelve solenoids gave us control for two
manipulators, plus rudder and dive planes (with some variance depending on
the sub). All of this was mounted internally. Eventually, perry went to
external compensated pump/solenoid boxes for the manipulators, but by then
the subs were up in the one point five to three million dollar range. The
resultant increased budget and their growing experience with work class ROVs
made that practical. All the later boats were set up with the external
package, as far as I know.<BR clear=none>Vance<BR clear=none>Sent from my

[PSUBS-MAILIST] Manipulator arm<BR clear=none>> <BR clear=none>>
Scott,<BR clear=none>> No matter how you do it, a manipulator will cost
some of money. I have made<BR clear=none>> many and the tendency
seems to be, to try and make them strong to lift a<BR clear=none>>
lot. Well first off, I think it was Vance that said it best. A
manipulator<BR clear=none>> is for manipulating not lifting. With
that in mind, large components are<BR clear=none>> not needed.
Simple air cylinders from ebay are all that is needed. A 2in<BR
clear=none>> bore and depending on manip design, 4in stroke, maybe as
much as 6in stroke<BR clear=none>> is all you need. Keep the rod
size small at 5/8, that reduces the back<BR clear=none>> pressure.
I have said it before, I love convertible top pumps. Consider<BR
clear=none>> using one pump per function again purchase from ebay for 125
bucks. No need<BR clear=none>> for valves, the pump simply runs in
reverse to change direction of the<BR clear=none>> piston. Keep the pumps
inside the sub and it is real simple. As for the arm<BR
clear=none>> itself, if have made them from cardboard first. You
can mock it up that way<BR clear=none>> and find the best pin locations
for the cylinders and ensure the cylinders<BR clear=none>> stroke
properly without over centering. You can build the arm with square<BR
clear=none>> tubing, use 3 inch aluminum so the cylinders fit inside when
the arm is<BR clear=none>> folded up. Forget about a wrist until
you have lots of time to play around.<BR clear=none>> Four functions will
serve a psubber well and can be built for under 1,000<BR clear=none>>
dollars. I can send you a convertible top pump to play with if you like.<BR
