Hi Dean. I saw your latest pictures and your's is looking good too!. Thanks
for the encouragement. It sure takes a lot of grinding/sanding to put one of
these things together. I should have stuck with the simpler shape, but once I
got started on the damn foam, I was having too much fun. The next step on this
piece is to pull it off the hull and stand it up vertically so I can reach the
bottom half without laying on my back. As I said, it's been a learning
experience, and is getting easier ( well, OK, maybe just a little.)
I'm ready to buy the nipples for the thru-hulls. Stainless schedule 80 for
the air/water/electrical/hydraulic systems. Looks like I need about 20 or so.
Man, that's a lot of holes!
I'm trying to design a hydraulic system without using a pump to drive
the rudders and dive planes. Basically a master cylinder and slave cylinder
set up. It will need to be double acting so I'm either looking to buy the parts
or maybe get my machinist son-in-law to make them. I was thinking if I use a
pressurized reservoir tank to maintain pressure in the system, ( with a scuba
tank hooked into it) it should keep any water from entering the external
actuators. I'll build the system on-the-bench and see what works.
If I can't get it to work, I'll go with electric motors with screw
type linkage.( really, more simple.) I was just trying to avoid using
precious electrical power on any system that could use muscle power.( and no way
I'm putting any rotating shafts through the hull.) Another thing was the
dive planes/side motor mounts need to be able to "fail" in the vertical
position. This may be a problem with the screw type linkage. Still thinking that
one through.
Did you see the link on the little video camera? check it out, looks pretty
nice!. ( wonder how much $ )Anyway,see ya this year at the convention. Frank
