P3D RBT Tracks

["John Goodman" <jgood@xxxxxxxx>]

It'll take time to go beyond my novicehood, so at the 
moment I'm a one trick pony when it comes to mounting. I 
can stomach the cost of RBTs for the few rolls a month I 
take, and find them easy to use.

They would not be if I didn't have a secure slot for them to 
fit into, on my light table which doesn't move around. With 
tight fitting pin bars, I couldn't enjoy setting the window until 
I immobilized the mount frame, so my fingers could be free 
to apply force just to one side's pin bar at a time. A simple 
fixed stereo magnifier yields a dynamic view of window 
changes, and is high enough to allow fingerwork on the 
mount underneath. I used good double stick tape and three 
thin aluminum flat bars to make a U-shaped receptacle 
stuck to the glass, that all RBT mounts fit into.
