Are those galvanized iron tees, and how are they connected and sealed to the frame tubes? It's an interesting approach; I'm just curious about the details.... coolant system within the metal frame work.

That's reassuring!They are only in galvanised for prototype I have ordered stainless steel pipe and tees to replace them with as galvanised does not cope well with coolant.
I was thinking that you were going to use the frame sections as pipes, but it sounds like you will just be using the frame sections to enclose and conceal the piping... which makes sense but is very different in construction. If that's the plan, then where fittings come through the frame section wall I would want some form of bulkhead connector, rather than just having the frame section wall trapped between the parts of a common pipe thread connection. Does that make sense?Within the box section there is a piece of pipe with one tee and one 90o elbow with threads on the end that pop up through two wholes in the frame the tees are then screwed to them in which I will use ptfe or some sort of temp proof thread lock. The tee and 90o within the box section will be stainless tig welded on so they are completely sealed and can never leak.
Hmmm... I read it as the piping and connectors internal to the frame would be welded to each other (to keep them from unthreading or leaking, because they are inaccessible), not to the frame. The welded assembly of piping and fittings (a tee and an elbow) would be inserted into the frame tube from one end, then the visible tees would be threaded onto the protruding fitting ends; the plumbing assembly would be removable for inspection, repair, or modification.I read that as the stainless end pieces of piping will be welded to the frame solidly so the connectors will seal against the welded piece and the pieces will return strength to the frame where the hole was for it to exit...

Correct I did consider building frame out of stainless and using the box as the pipe but is a pain when regulating flow plus need to put fittings into the bottom of the frame to hold the outer box.
Since we're into fabrication methods... welding pipe-threaded fittings should work (particularly since this appears to be a low-pressure application), but that's not how they are intended to be used. If the internal connections are going to be welded anyway, there's no need for the threads at those connections at all.
Hi Chris
For our clarity and sanity, please confirm which POIs you are welding and how the pipes are retained in the frame.
Thanks
