<font color='black' size='3' face='Arial, Helvetica, sans-serif'><font class="Apple-style-span" size="3">As to mounting things inside, we machined about a jillion little lugs to weld here and there on the inner hull. Half inch SS rod drilled and tapped for 1/4 20, each about 3/4" long. All the manifolds and gauges and whatnot were assembled on flat panels which were then screwed to the lugs. Once in, all you have to do is bend tubing to hook everything up and you're done. It's a nice way to do things, utilitarian, easy to maintain (and leak check), and dead simple when it comes time to paint or whatever. We used airtight zero boxes for the electrical distribution and so on. They mounted the same way (usually bolted through from the inside with rubber washers for a clean installation). All this is/was done on paper first, so the weld shop could just measure it out, and then the mounting holes were matched and drilled in the fab shop during outfitting (that would be me doing a whole lot of that in the pictures). A bit time consuming, but simple as pie. I prefer this kind of thing to slick flush-mounted everything style panels, primarily because it is so simple to maintain. And as a side note, panel mounted valves don't stress fittings and tubing when operated, so that was another plus, operationally speaking.</font>

I don't have a pic or drawing of PC8 without the MBT's, but there is one of PC 14 in the Busby text with the rings as you described. Now I see how to place them and the rationale where the shell is concerned as opposed to having anything to do with the CT ring itself. Moving these outside really opens up the inside dramatically.<br>
<br>
I suppose one could do an erector set type tubular AL frame inside wherever equipment has to be hung ala Alvin's birdcage.<br>
<br>
Thanks Vance, that reference to PC 14 was helpful!<br>
