So, this thread has been rattling around in my head for awhile. Awhile back I bought the K&M 18950 and some accessories, as described here. What's nice about this stand and the accessories is that there are lots of ways to configure it. But once you have the stand configured, all the knobs and such get to be rather fussy. And the tubing used on the second tier supports has a very large diameter, and this diameter limits how low the upper key board can be. My thought was, what if I welded up something super simple that was just the right height, so no adjustments possible, and make it out of smaller tubing so the keyboards can be closer together?
For larger gigs I use a Stage 2 compact for pianos and synth, and then an SK-1 up above for organ. I would like to have the organ manual as low and as far forward 99% of the time, but be able to slide it back occasionanly to access the Nord's control panel. So I've been very interested in what Mate Stubb and Daddyg3042 are doing with the sliding top layer. I'm thinking of doing something similar but much simpler. Instead of having an actual sliding mechanism, just have a long flat surface that I can slide the SK-1 back and forth on. The trick will be to find a material to put on top of the bar that provides enough friction to hold the board in place, but not so much that the board is too difficult to slide backwards. Rubber strips might do it.
Awhile back I bought a ten-foot length of rectangular steel tubing, and I had a couple free hours this afternoon and decided to have a go at it with a mig welder.
Here are the upper bars. Not much to it, really:

Here's what they look like when slid into the accessory slots on the K&M and the set screws tightened down:

Here's what the access looks like with the SK-1 slid all the way back:

And here's a side view with it slid forward.

I wasn't sure how stable this long span was going to be, but it seems pretty sturdy. I don't like the height, though, and when I get a few more free hours I'ma weld up a new one where the upper support bars just barely clear the Stage 2's controls.
