I am currently building a freelance loco in 7 1/4 in, and found some conflicting "statements" in LBSC'S Shop shed and road describing Baker valve gear for locomotives, Page 100, 101 in where it says that the the valve spindle goes on the top hole of the combination lever for outside admission (slide valve) and below for inside admission (piston valve). However in the book from the Pilloid Co it s the opposite. did any builders used Baker valve gear and came across this problem, or am i off course or missed something?

I just checked SR & S. That has got to be a typo or similar. Follow your other reference.

I suggest that you download the late Charles Dockstader's valve gear simulation software from
**LINK**. The software is old but will run on a PC although you may need to run it in compatibility mode for Windows XP.
Then run the files for Baker inside admission and then Baker outside admission: Bake_IN.exe and Bake_OUT.exe respectively. These show the same arrangement as you have seen in LBSC’s book i.e. Baker outside admission has the valve spindle connected to the top of the combination lever with the valve rod below it. These positions are reversed for inside admission piston valves. The software allows you to see the effects of altering the dimensions of the components and obtain graphical results.
