[PSUBS-MAILIST] drawings

Hank,

If you have a look at Fig 12.31 in Jerry Stachiw’s Handbook on Acrylics it has a good diagram and the angle is a cone with its centre at the centre of the Sphere so it will depend on the diameter of the hatch and closure.

If it works with Acrylic you can bet that it will do the same on Steel.

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.

Alec,

Thank you very much, that was fast.   What I am looking for though is a deep diver hatch design with a  conical bearing face.  I have some good pictures, but no dimensions or angles etc.  I could also use a drawing of a conical port frame.  

Thanks' again Alec.

HI Hank,

I've got a big blueprint of a Perry hatch. 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,

Alec

Hi all,

I am looking for drawings of a Pisces style hatch  or similar.  I would like to copy what is proven instead of starting from scratch.  If anyone can help, I would appreciate it.

Thanks'

Hank
