That's correct. I will post a drawing in the next day or two that

Yes! Congratulations to John! He absolutely must share the details about how
he did it.
Now who will pick up the challenge and make a coal-fired Ruby?

This begs the question: what are the components and steps necessary
to make a conversion from gas to coal?
Have the conversions John Shawe has made been from gas or alcohol?

John Shawe makes a new locomotive style boiler that fits into the old
space. He does not use the original boiler. He does reuse the fittings
such as the water glass, safety valves, throttle controls. He adds a
blower control if needed and rebuilds the rear frame to accommodate the
locomotive
Dave:
John Shaw makes a new locomotive style boiler so the original fuel source is
not material to the converted engine. Major issues are space between or
above the frames for the firebox/ashpan. From there he needs some new
plumbing for a blower and nozzle and in many cases he puts an axle

Boiler and smokebox, exhaust nozzle, feedwater pump(s). Did I forget
anything? I'm not sure Ruby has room for a sufficient firebox between her
frames, though one as long as my dummy
There's an echo here in the small scale list.

Glad you mentioned the nozzle and axle pump Jim. Another modification
needed is a way to open the smoke box door so the flues can be brushed.

It would be possible to modify the frames by carefully bending them wider
then adding to them so that the firebox could ride between them. If you
remove the cab floor the frames are just left hanging there. :)
You'd have to get it just right though as the axles could bind if the

John has converted the well known gas fired Roundhouse Sandy River #24 to
coal as well as others. I read an article some time ago in Tom Cooper's
Steamlines where John reboilered an Aster Schools to coal fired. I recall
Congratulations, John! Now, tell us how you got it to breathe. When I was
there a month or so ago, John and Landon and I brainstormed about why
John's boiler was so short of breath, and how he might modify it. I'd love to
hear what it took. Homebrewed coal-fired boilers are pretty rare
