RIT dye? Please tell us there will be a tie-dye version.
Are you able to get enough grip on the hex heads to tighten and loosen? Is there any tendency for the mounts to move when you tighten it?
I have no desire to make more than I need myself. Maybe you could adapt it and make some out of Delrin if there is enough interest? Or someone could make a bunch the way I did.
The most expensive part is the Audix clips. They sell for around $10 each. Maybe there's another less expensive option for the clips. I just used what I had around the house at the time.
I did buy a PVC cutter at Ace Hardware for $15. Cutting the prototypes with my cheap miter saw was too much work, because I had to sand the ends and I wasn't getting accurate cuts. The PVC cutter makes very clean and accurate cuts.
The PVC pipe I bought has a wide tolerance on the ID and OD wall thickness. The ID is pretty far off center on every piece I have bought. For my purposes, that's not a huge factor, but it's not perfect.
The 3" nylon bolts are around $1 each at Home Depot. PVC pipe is cheap. The O-rings were around $3 for ten at Home Depot.
I have tightened the fixture I made with wrenches, so it's pretty tight. But, it's still possible to move the clips for different angles. The way it is now, the nut and bolt don't move at all when I adjust the angle. But, it works pretty well when it's just hand tightened too.
One more thing. I replaced the bands in the Busman shock with some nice black hair ties I found at the Dollar store. They are solid rubber (not fabric covered) and are more taut than the bands on the stock shock mounts. I'm hoping they will be tight enough to accommodate the fixture with my C-480 bodies loaded. I haven't done any bump testing on the stand with the new bands yet. So, that's something I have to do.
