<div>Alec,</div>
<div>Could you tap a small block and weld/adhere it to the top of the can for
the entry point for your elbow? That would eliminate any protrusion into
the top of the can. You could substitute a T with a bleed for the elbow
and even add another fill point at either the top or the bottom.</div>

so. Life and work is holding me up. <br>I have my new trailer
ready, I built a hydraulic actuated idler wheel. The system raises the
trailer off the ball as well as allows the trailer to roll into the
water. I use a tow strap rather than an extendable bar because the ramps
here are long and steep enough.

5:52 PM<br><br>Thanks<br>Hank. Looking forward to hearing how it goes. For my
part I<br>have trouble with the oil trap method because of the fact<br>the
thrusters rotate. But I'm going to try the<br>following. The old method is a
hose wound around the cans<br>between an elbow at the top and one at the
bottom. To fill,<br>I disconnect the tube from the top elbow and add oil
through<br>the tube until it flows out the top. The problem is a little<br>of
the elbow protrudes inside the can, even though I trimmed<br>it, so its hard
to get every last bubble out. The plan is to<br>replace the tube with a
plastic bellows bottle attached to<br>the bottom elbow, and put in a set screw
in the hole where<br>the top elbow is. This would do two thing;
significantly<br>increase the compensation volume and sensitivity of
the<br>bladder, and eliminate the protrusion caused of the elbow<br>inside the
can. I'm pretty confident this will solve the<br>issue, but the only problem
is I don't have any dive<br>plans in the near future to find out.<br>Let us
know how the trap approach<br>goes!<br>Best,<br>Alec<br>On Sun, Jun 14, 2015
