Re: [PSUBS-MAILIST] Welder with Vision

[robertbatta@comcast.net]

Thijs,

That is the design I had in mind.  My last sub was a single occupant in the prone position, I am looking to "upgrade".

I realize the design is complex, Im hoping to get feed back from you all on this.  To answer your question, yes, this is the design I had in mind, two occupants, one in front of the other. 

Thanks,

Rob
