 Hugh,Thank youThat is the idea alright but it does not give an angle, unless the drawing is to scale, I could measure it.Hank

Subject: Re: [PSUBS-MAILIST] drawings  Hi Sean,Whenever I look at a deep dive sub it has conical bearing surfaces.  I have to assume the hatch load is transferred into the hull better with an angled seat so that the load is directed both down and outward.  I can copy what I see in pictures, but I am afraid if I don't have the angle just right it could bind.  I am not concerned about sealing, more how the load transfers into the hull.Hank    On Thursday, October 29, 2015 2:00 PM, Alec Smyth via Personal_Submersibles <personal_submersibles at psubs.org> wrote:  Ah!

I'll send you a photo offline - it needs to be full file size for you to see anything, and I don't think it would make it through as an attachment here.    Best,
