brohawk And... done. Light works and it stays upright all on its own. That's just a derimmed 2.5 gallon for size comparison. Final pics:

brohawk Everything's now painted and I'm almost finished sorting out the wiring. Updated first post, photos also below.

brohawk And... two years later I got around to sanding and priming it. Dry fit photos updated in the original post. More updates hopefully to come.

brohawk Forgot to mention; I found some rubber gaskets that are the same 1/4" ID as the tubing's OD which you can see in the last pic. This makes the fixture's position much more stable, and won't scrape the eventual paint job up when adjusting the height and/or length.

Weather's been pretty crummy up here lately. Not sure when I'll have a nice enough day to start the painting process.

CPDzeke No updates? I kinda need a full tutorial.

kingjombeejoe I like the look of the rivets it makes it yours and not a copy.

brohawk Thanks again everyone. I'm looking fwd to seeing its final form as well.

Yeah, I'm not worried about JB Weld withstanding the heat alone. I've used it on a few automotive projects where plugging a hole was in order and it definitely stays put. But I'm uninformed and thus concerned about its bonding properties, even w/ just a little heat, when used between 2 flat surfaces instead. Next on the to-do-list is bonding a sheet of metal to the base, that goes under and thus is weighed down by the aquarium. The weight of the top part of the light will require a good bond between the base and this undersheet. Anyone have opinions on whether the JB Weld will hold? Sure, roughing the two surfaces up beforehand should help but will it be enough? Or should I stick w/ the tube of metal epoxy I also have on hand?

Great job by the way.

pweifan You're a natural. This turned out really well. I'm looking forward to seeing the end result.

Very impressive !

brohawk Thanks very much for the compliments. Yes, welding would be the obvious choice here. And while I do have access to a buddy who's a professional welder, I wanted to try this w/ just some common tools instead. Like I said in the initial post, I could have reduced the number of rivets from 6 to just 2 in the top of the half-pipe. Especially if I used slightly thicker sheet and a little epoxy or JB Weld to bond the sheet to the arcs made of flat bar. I don't know if I'd trust it to last long once in operation w/ the heat the bulbs put out if I just used epoxy and w/o at least 2 rivets. You could use smaller rivets though, for sure. I chose larger as I thought they actually might detract less, being flatter than smaller ones. Personal preference though. The 3 rivets in each end cap would probably be unavoidable but I used smaller ones there anyway.
