Hey! I already commented today! And now you post something so cool I have to think about my post again.

Well I'm not going to.

Not until I can come up with something better than 'wow!'.  :o

Did the cylinder cock lever open them on all the engines at once?

Chris,
I love watching the parts come to life from a block of metal. My favorite kind of work!

The one lever opens all the drains on the hoist and slew engines together. The steering engine was on a local lever, but that is next to the boiler backhead, so the boiler engineer could do that one. The crowd engine drain and throttle was on a set of levers at the lower pulley on the turntable. Very different having four twin cylinder steam engines on one machine.

Thanks George! I love sculpture, getting the useful shape out of the block!

I suspect I'm not the only one left speechless on this build.  ;D

Hey Chris,
Amazing work, as always!  :ThumbsUp: :popcorn:

Kim

Even if you did chew up 99% of a perfectly good big chunk of beautiful brass!  Lets see, $1.25 in brass for the part, and $95.75 of brass swarf.  Sounds like a deal to me!  :o

Have a great day.

No where near that bad, the bar was only about 1.5" long, didn't pay $100 even for all 6 feet of it!

The last steps on the bracket are done, drilling/tapping the 0-80 mounting holes, and cutting the notches for the latch with a fine blade hacksaw. Its all assembled on the floor and working well, ready to start connecting up the linkage rods.
Kim, as you can see here, the part is pretty small, so there was not mutch wasted on the bar stock:

Getting close to finishing the work on the under-floor controls (later on when the cab is framed up, there are two more that hang from the ceiling). I made up the handle for the dog clutch, and the hoist drum brake pedal. Both were silver soldered up from two bits of flat steel. The top of the pedal was held in place for soldering by drilling a hole in the top, and turning a matching post on the end of the shank. The L-shaped pieces were just set next to each other on the firebrick for soldering. After soldering, they were cleaned up and shaped on the belt sander.

Here is where they will sit through the floor - they were just propped in place for this shot.

And the control rods that run from the hand levers back to the cranks under the floor were cut to length and the fronts loctited in place in the clevises.

These rods were cut about half the length required, and have a short tube coupler on the other end, held with grub screws. When the floor assembly is put back in the frame, I can feed these rods through the cross frames. Then, I'll be able to measure the exact length needed for the remaining parts of the rods, loctite them into the rear clevises, and then screw them into the couplers. That way the controls can always be removed for any repairs or changes later on without much trouble. The full length rods would be tough to feed into place and get the clevises bolted in otherwise - on the real machine there is room to get a person into the gaps in the frames with tools - on the model, only a shop-elf will fit, and they are too hard to bribe for this kind of work!
