Hello My Friends To answer Roberts question, #5344 did not have a valve pilot as built. I will be building the engine as built with slight weathering (not shiny). Although the drawings I have show a mount for the valve pilot. They are a cool little detail but I won't be including that on the engine....

Hello My Friends Managed to get a bit done on the running board, air reservoir, power reverse, piping brackets, and distributing valve mount. There is quite a bit going on here. As usual a card stock pattern was made and held up against the boiler jacket to have a look. The main thing is that the po...

Hello My Friends
Thank you very much for your most generous compliments.

The 5/32" round pieces were tap drilled for a #1-72 tap before assembly. Here is the whole mess silver soldered together. It was then faced off, drilled and had the center cut out with a brand new 9/16" end mill. It was parted off, and then the packing ring was also parted off. The next two photos s...

Hello My Friends It was brutally cold here today with the wind roaring. Good day to hang out in the shop near the heater and fiddle with the Little Hudson, mainly the masters for the power reverse. One end of the reverser has a packing ring with five bosses around the shaft that links to the valve g...

Hello My Friends

Hello My Friends The power reverse will be a dummy. It will house a 1/4"x16 left hand acme threaded rodent nut. There will be a corresponding acme threaded rod in the indicator and hand wheel assembly in the cab. I will be making masters and will have the casting sets available along with many other...

Hello Mt Friends Here is the start of a Franklin precision power reverse. This mounts to the last running board support to be made. This support also holds one end of the right side air reservoir, the Westinghouse distributing valve and some piping brackets. The reverse needed to be made before the ...
