Hmmmm.....how about a "spaceframe" made of smallish diameter copper tubing brazed together (think "Bird Cage Maserati"😉? The CTTL ("Copper Top Tube, Lugless"😉!
Almost hate to comment on it, but in the oil field pipe dope is used so that you can later break threaded joint apart. That might not be such a good thing here.

Almost hate to comment on it, but in the oil field pipe dope is used so that you can later break threaded joint apart. That might not be such a good thing here. When I was working in East Texas (back in nineteen and sixty-four) 'dope' was used to seal the weld joints on pipelines. Not Pipe Joint Compound - that's used on threads. This stuff was the most God-awful, obnoxious stuff I have seen. Most guys on the crew would break out in hives just from the fumes. It was usually brushed on with a six inch brush like house painters used, but we had one little guy in his fifties who would use cotton gloves to slop it on. Stuff didn't /appear/ to bother him. I've often wondered how long he lived.
