No. All but the small test drums are made of Noryl, a very expensive thermoformable plastic known for excellent temp retention or insulating properties even thin-walled. For anything mid-sized and affordable, I'd simply use ordinary thick-walled black ABS DWV (drain/waste/vent) pipe. Bigger still, opaque irrigation pipe, hard to find in urban areas, but commonly used for irrigation. My former office had a big plastic pipe specialist diagonally right across the street - everything from tiny micro-pipette medical tubing to a huge selection of industrial chemical piping up to seven feet in diameter; and valves, oh my ... if a local refinery needed a $5000 pure teflon valve, they had it in stock. It's amazing what's out there; but affordable is a slightly different topic, so I'd look to more ordinary sources like agricultural irrigation.
I wonder if galvanized steel would work for tubes? I'll probably just buy some to test with. a 12" wide duct sealed with some epoxy and a cap on either end should work I think, as long as the material doesn't affect the chemistry
Consider T-slot aluminum extrusion, very common for mechanical industrial low volume devices. Here is just one example:

Bernice jogged my memory
I have used the older company, one is in Ohio and the other Indiana
In factory we used https://8020.net/history as soon as it came out for prototypal assembly line and test fixtures
I have a Dreamer 14X17" camera on hold, started 6 years ago, using 8020 with sliding bearings
I will get it out of deep storage and post pictures, perhaps today
I already posted it 5 years ago in DIY, but may have deleted the images
ULF film holders are expensive, I also made several DIY ULF conversions, those pictures are in DIY, search for Levy Process camera under Randy Moe

Here is my base sled, I will be restarting a DIY thread about it, so as to NOT step on your toes
You have re-inspired me
Thank you

Looks good! The black anodized aluminum definitely looks nicer than the plain, if it wasn't more expensive I would definitely use it for my enlarger design.
How are you planning on controlling focus? A few months ago I toyed around with the idea of building a lightweight 8x10, which had a belt driven focusing system. Even though gear slop really isn't an issue for large format cameras, my thought was that a belt system would be even smoother. I abandoned the project since the carbon fiber needed to make it started pushing it into the price range of already available carbon fiber 8x10s, but it was a fun thought experiment.
