I've been playing with the video camera and doing some simple things so I can learn the editing software. I just rewheeled and serviced the cast iron 4670 loco and decided to do a video showing the different types of valve gear.
The earliest valve gear was a simple straight valve rod. The picture below shows the loco I rewheeled. I should have bought the other rods and done the who set up.
The picture above shows the smaller ex-IVES cast iron body. This simple set up was also used on the diecast steamers like the 4692 below with the triangular valve gear:
The most deluxe FIVE PIPER locos had lots of added trim and usually had Walschaert valve gear. The rods are much more involved. Here's a 4694 deluxe loco:
Here's a video showing the 3 locos running:
Two notes. . . I don't have the correct tender for the cast iron loco. The five piper loco shown above is brown without a green stripe. Usually these are painted the same way as the 4692 loco shown.
