Thanks to everyone who has responded. I will try to find a suitable 
material to 'capture' the threads as most helpfully described by Erik 
Levin, and will post my results. The Christmas season is descending upon 
us shortly, and I doubt I will get to this very soon. When I made the 
original post, I was hoping for a quick solution. I see now that that 
will not happen, but I am a patient guy. And starting in January is 
another year! If you see me in the big box walking around with calipers 
measuring random suitable odds & sods, you will understand...
