The point of my question was trying to help me evaluate the performance of this machine, my first "Standard".
I've fiddled and twiddled with the upper-works, removed and completely cleaned the mandrel, feed-screw, pivots, back rod, and carriage, and cleaned and buffed all bearing surfaces where possible.
After reassembling, I tweaked the adjustable pivot points to where things would drag slightly, then back-off the adjusting screws about ¼" turn ( and physically pushed the pivots back against them).
I now have it running where it will play about 3-½ Indestructible 2-minute cylinders, with a 14" black & brass "witch's hat" riding on the Model C reproducer. About half-way through the fourth attempt, it begins to drag, and 2 turns of the winding crank gives it enough juice to pick-up and finish the cylinder.
If I had a morning glory on a crane, I think it would pull through four cylinders...
I haven't touched the bottom works, aside from oiling. When the weather warms-up, I will tear that down and clean everything, including the mainspring.
I'm pretty pleased with it so far...
