<div dir="auto">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.<div dir="auto"><br></div><div dir="auto">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?</div><div dir="auto"><br></div><div dir="auto">Best Regards,</div><div dir="auto">David</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Nov 3, 2018 7:38 AM, "Alec Smyth via Personal_Submersibles" <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">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...<div><br></div><div>:)</div><div class="signature-text"><div>Alec</div></div></div><br><div class="gmail_quote"><div class="elided-text"><div dir="ltr">On Sat, Nov 3, 2018 at 2:27 AM David Colombo via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank" rel="noreferrer">personal_submersibles@psubs.org</a>> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="elided-text"><div dir="ltr"><div>
Hi guys, the SeaQuestor pressure hull is well underway. All sails are fit and tacked, all thru hull openings are finished. Even the periscope tube was fit today. still need to complete its penetration thru the bottom of the hull. Next week the rear tank and thruster rack, forward camera mount, and bottom rail to be completed. I expect to pick up the completed hull with the trailer the next week. Then off to the sand blaster and then the welder. This weekend's job is to get the trailer prepped.<br></div><div><br></div><div>I do have a question for the group. I am debating as to whether to weld the lower frame rail system to the pressure hull, or weld tabs to the hull and then bolt to the frame rail which would allow for removal. The frame rail system will hold the drop weight system. I would like your thoughts.<br></div><div><br></div><div><div dir="ltr" class="m_-7803216424759677004m_-4422307562336653267gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div>Best Regards,<br>David Colombo<br><img src="http://static.squarespace.com/static/533310a9e4b0fba62008a464/t/5339c1f2e4b041bac4e25d1b/1396294132055/?format=500w" width="200" height="110"><br>804 College Ave<br>Santa Rosa, CA. 95404<br>(707) 536-1424<br><a href="http://www.SeaQuestor.com" target="_blank" rel="noreferrer">www.SeaQuestor.com</a><br><br></div></div></div></div></div></div><div class="quoted-text">
