Hey Dave, thank you for those links, very helpful. I did some measurements and found I needed a slightly longer version (the male threaded portion) of the Grainger standoff, and found one at McMaster-Carr and ordered four of them to try. Jeff at OecCamera was very good about it, looked for a solution on his end, but in the end, he gave me a $20 discount to find my own. I'll let you know how it ends up.
Thanks again.

This is the PCB Technical Forum and we've strayed pretty far afield in this thread but, hopefully, the moderator(s) will allow me to offer you one more option for using the OEC speedring with your Einsteins. Here's what I've done:
I drilled out the 3/8" threaded hole in the ring's mounting platform using a 3/8" drill. In the hole, I installed this adapter:

With this adapter in place, the ring can easily be used on heavy duty swivel like this:
But the real magic is in the other set of holes. With a length of 5/8" aluminum rod and a standard griphead, the ring can be mounted like this:
I did drill a small dimple into the front of the aluminum rod to prevent the ring from twisting to one side and also installed an 8-32 screw that can be seen poking out of the grip head. The screw prevents the assembly from flopping to one side or the other when the grip head is loosened to aim the light. The aluminum rod also serves as a handle. The back end is covered with a length of heat shrink tubing.
If you're not happy with the spacer solution, this approach works *very* well.
