the stand is not the problem, the shelf is.
I was confident I could put a rack half shelf on the front of the unit because I forgot that the nuts were in the way. The plan was to hang the rack shelf off the holes in the front of the rack so it can be adjusted to any height, but I am not getting a good face to face connection on the flats because there is shelf nuts in the way, so basically I need like a extender. with hooks on it. It needs to be like a comb that fits between the nuts and makes a true connection
it would look like a lower case pi shape foot thing
And if I make more stands, its SUPER tempting to copy the HP stand that i Need to take pictures of. It looks like a cone. It has enough space in there to put a commercial collet in there for a small adjustable post. Then you just put different forks on top for different wave guides with a universal stand.
I got one, can't find more, but I HIGHLY recommend that design. Its just a shaft that gets tightened into a cone, and the shaft has a hole on top that you tighten a fork into. Easy to make out of brass but my 3d printer is too small to print the base in one piece. I want to do it with some collets I found once that you thread into place, instead of a side screw, but even so that one is easy enough to make with a hole saw, some metal plate aluminum, drill bits and brass rod for the center post, and you can even put it on a turned wood base no problem.
But the uh, attenuator, I think it was pulled from the side wall of a B52 or something, very irregular mount.
