[PSUBS-MAILIST] SeaQuestor Update Thru hull plates

[Alan via Personal_Submersibles]

Hi David,
I'm a bit confused about how that is working! Is there an o-ring either
side of the ring of bolts? Is there a small o-ring on each bolt? 
And what is being welded? Also if the bolts are press fitted how are they
tightened.
If it takes too much explanation I'll wait for the progress photos.
Cheers Alan

I designed them with shoulder bolts machined down and press fit into the backing plate fit for future modificatations or bolt failure. The outside plates are machined down with a shoulder for alignment to the interior id and with an oring seal. Each plate will accomodate (5) 3/4" blue globe fittings. The center hole is for the carbon fiber air line to be routed to the thrusters for air compensatation. The 4" plates accomodate 1/2" blue globe fittings. Test fitted the 6" and I'm happy the accessability. Almost ready to send to the welder.
