Hey.  The hemispheres were hard to find.  They came as rough sections from "Commercial Metal Forming" Orange Co. CA.  cguido@cmforming.com  Tell her I said Hi. :)

Thanks for the reference!

They are 3/8 thick and 36 in. in Diameter.  They were just under $1000 .  But the Co. has sent me a warning that steel prices are going up.

More than I'd hoped, but less than expected.  I'll need one 28" in diameter and 1/4" thick.

and a whopping good deal on a piece of 1/2 gas pipeline remnant,  $170. 

Nice scavenging!  Used or new?  Do you know what grade of steel?

A local weld shop has adopted me and Rod is an employee there.  I am paying for their services.  ( cut rate so far).

Convenient; friends are nice.  Brian took the route of taking welding classes at a community college and was fortunate enough to find an instructor that warmed to the idea of his project.

I have about $4200 invested so far including a $1000 failed attempt to make my own motor housings, and $400 in machining costs for view ports and hatch cover 'O' ring seals. 

Ouch! on the $1k motor housing mistake.  Care to share the nature of the mistake?  Are you closer to projecting a final cost for your sub?

They cutting and grinding of the hemispheres took many hours.  I've used (6) 71/4 grinding wheels so far.

Cutting?  And is that pre- or post-weld grinding?

 

Warm Regards,

Shawn
