Scott,
One thought on the bladder for compensating the depth
gauge, is
to use a marine light housing. Take the glass out &
replace it with
rubber from a car inner tube. Seal it well &
as long as you bled all the air out of the
system the rubber would have very little travel & not
much tension on the
clamping area. Also some lights have a short threaded pipe
that the wiring
comes in through. May be very little work if you found the
right item.

It is in Dan Hryhorcoff's project photos. Picture 24 and 25.
It is the black rubber thing with the metal ring. Can't seem to find
anything like it. Anyone have any ideas? Also what kind of oil do you think
you would use, maybe just a lightweight auto oil or something even lighter?
I'll be uploading more pics soon. I have made tons of progress including a
really cool new thru-hull design that is basically
complete! Thanks, Scott

Hi Brian,
It's to protect the innards of the depth gauge
from corrosion from seawater.

Why do you need a bladder for the depth gage?
