Yes they are Bruce. I watched your little vid unboxing it. It's good scale and slick working. It makes it easier to slow down the hacksaws to a realistic speed. It would be fun to go to chain drive and see how much weight could be loaded on it. Sort of like the Bowman 110 or whatever that gear reduction model is. Someone on youtube used a can opener reduction drive to lift like 150lbs with a model steam engine. I like playing like that!
