A full Saturday yesterday. Spent the morning finalising The Intangible Man audio. Only when uploading did I see that the cover designs demand a blank space in the lower right corner for promotions. This template isn't stated anywhere in the written guidance, it's only there as a mask on the upload screen. Ah well, a quick adjustment (which, incidentally, does knock the design out of balance) and it was ready. All submitted. I must wait 10 days for approval. I'm still unsure of what to file.
Then, work on the light stands. I started by drilling the 6.5mm holes for the light stand legs, so all 4 are now complete apart from the little 'notch' things to hold them at the right angle. Then work on the music stand.
The mic thread adaptors arrived, so I fitted 1/4" bolts into the mic holders, then set up the stand to measure the width. 12mm holes were drilled into the wood, and the mic holders were fitted into a little bath of epoxy resin to hold them. A few hours later, I drilled the holes for the bolt collars (for the main sheet music plate) and painted it black before fitting those collars, this time using paraloid resin to hold them, which is much more polite as a glue than epoxy (though not strong enough to hold the mic holders, and it dries by evaporation, so not suitable for a cavity).
Here is the result:
You can see here how the top tier leans in to make a trapezium, which is part of the problem. The Reface, by chance, holds it becase its base isn't flat but has an extruded middle.
Of downsides/possible improvements; I'm unsure of the strength of the epoxy, although there is really no alternative other than more tightly drilling a hole for a better mechanical grip. It may have been nice to make the mic clips removable, but the lengths of the screw threads make this difficult. They might be, even now, unscrewable. I didn't tighten them for this reason (of course, I still needed to orient them exactly, so couldn't fit the screws without the mic clamps).
So, all is done, and the music holder can be removed and attached as needed, which is a huge bonus. I don't want a big thing like that hanging around for once-in-a-blue-moon music performances.
