Chet, JWB, thanks for commenting.
I built the jammer using a 45' flat car and steam engine from a Woodland Scenics kit (was part of a fanning mill I think). I put a wood deck on the flat car and made the sides with some scale lumber and toothpicks for posts. The little shed is just some scale 6 x 6's and scale boards and scratch built.
I made the spools (drums) for the winch from a couple expansion pins and one drum is stationary and the other turns with the crank. The boom is carved from a couple pieces of soft wood and I made the top pully from a pully casting made by a detail company. I used stick pins for pivots and center pins and just forced them into the soft wood using a pliers.
I think the man running the winch came from a model power worker kit, and he was doing something else but he looked like a winch operator. The guy with the pickaroon (blue jacket) is by Prieser and came with some other loggers, the guys on the crosscut saw; and the two guys with the cant hooks and the guy unhooking and hooking up the tongs came in a packet of "dock workers" made by prieser. The cant hooks are made by Keystone locomotive works and I ordered them from valleymodel out of New York, I had a hard time finding the cant hooks but I have seen them by other mfgs as well.
I think that is everything but if you need more info just ask!!!
