I have a couple of strain relief gizmos that I've been carrying around
in my tool box since the early 1970's. One of them might be suitable for
your purposes. I'll try to describe them:
This device is made of aluminum. I believe it was intended for aluminum
utility cable, as they came from my dad who worked for Cincinnati Gas &
Electric. One end has a loop of ~1/8" AL wire about 1-1/4" across at the
large end, tapering to about 3/4" at the small end, where it is attached
to the part that would hold your cable. This loop can be removed from
the other end via a keyhole arrangement.
The other end is formed so that there is a tapered piece with about a
1/4" groove along the top. A larger piece is U shaped with curled edges
so that it slides over the other piece and locks any cable set into the
groove.
In use, one would open the loop, place it around some part of the
projector platform and close it, again -- something like a safety pin.
Then, one would lay the video cable into the other end, leaving enough
slack so that it did not interfere with the projector. Thus the weight
of the bulk of the cable is transferred to the platform, or its support.
I would be happy to donate one of these to the cause. We'll just have to
find a mutually convenient time and place for me to hand it over to you.
At this time, I don't know if I'll be able to attend the meeting.
Alternatively, if you know an electrician, you might be able to get one
from him/her. I suspect something like this is still on the market.
