[PSUBS-MAILIST] SeaQuestor build update

[David Colombo via Personal_Submersibles]

Hi Guys, Thanks for the feed back. The Rails are A516 gr 70 steel and
already cut, but I have some 316L stainless that I will now cut for tabs.
I'm sure my fabricator won't mind a few more laser cut parts.  I was
originally going to weld the front camera mount, and rear thruster and hp
air rack to the hull, I'm liking the idea to make them removable as well.
What's a few more ss tabs. I now have a week to get my trailer prepped to
pick up the hull for its trip to the media blaster. Always another project.

On a another note,  I was having a discussion with the welder about welding
the .75" ss hatch ring to the .75 steel sail, and then the need to machine
off the surface to flatten it vs why not just drill and tap into the sail
and bolt down the hatch to the sail with an oring. Both seem to be about
the same amount of work. Has any body ran this scenario before?

Best Regards,
David

Super quick progress Dave! As a general rule, everything you can bolt on I
would bolt on. The tabs for bolting should be 316 SS, and everything you
bolt on should be 316 SS too if at all possible. And the bolts should be
316. I think you get the picture...
