Crude made. But it works great. Still have to work out the 1/4" copper bends.
I need some suggestions as I cant think of anything. What would be a better method of holding each pipe to the acrylic disks than 24awg magnet wire? I couldnt think of anything, it was too late to really take it all apart to drill holes, so I just used magnet wire. From a far, who cares you cant see it. and it does hold well. I just wondered if theres any way i can do it without the use of wire as it looks so bad up close.
Another issue is the method i connected my 1/4" copper, with aluminum tape. I cant make a seamless finish, and you cant get copper tape locally. idea?
I understand that anyone is going to view it from a distance, and wont see these flaws. They will just see this perfect toroidal shape that seems to be somehow floating in air. But, I'm a man of up close detail work. I made my DRSSTC guts as organized best i can, so it looks friendly, simple, and neat. I used rather expensive lexan to have high gloss plastics instead of dull flat meterial. I would like the topload to look better without these patches of tape and wires. I dont have the tools to role tube, so its going to be cruel anyays, but still!

how about zip ties for the tubes? i guess that'd probably look worse than the wire, i don't know. I can't think of anything that wouldn't require custom cut brackets or drilling more holes.
for the copper joint, you could solder it, then sand it. it wouldn't look perfect, but it'd be better than crinkled tape, and shouldn't be too hard. then you can pick up some copper ribbon tape at a craft store (used with stained glass art) and put it smoothly over the solder ring.

True, maybe if they make copper couplings that for both sides for 1/4" tubes I can sand the ends of the coupling down so it looks like a gradual bump.
What about connecting all the rings together? Best I came up with was to take a long pieace of 26awg copper wire an twist it around each tube. Can't notice it at all from a distance :) I'm quiet happy with the out come of this topmosd, I just hate the bad job a company did with my 3/4" tube, the small inner circles are just horrible!

Why not just solder the ends of the copper pipes together? A pencil torch, sandpaper or steel wool, plumbers flux, and solder. It would be a practically non-existent seem considering the overall size of the topload. I was thinking that having the copper pipes being completely continuous would look like a shorted turn and effect performance, but only the bottom part of the secondary acts like a transformer, and the 'looks' like a resonator.
As for connecting all of the tubes, i would use a short length of thin bare wire soldered to the pipes, right where the acrylic formers are. I wouldn't even wrap it around the pipe, but you could just do 2 solder joints and wrap the wire around the tubing for the tubes in the middle.
