MTH Smoke Unit for WBB 773 Hudson?

It is possible. There are some videos on YouTube of fan driven smoke units in them. The only issue would mounting which in most cases a bracket could be made.

Thanks--appreciate it.

I use the standard MTH steam smoke unit with shorts posts on most of my upgrades.  If that won't fit, then I dip into the well for a smaller unit.  Here's how I mount them in brass steam.  I JB-Weld a spring to the bottom, I solder the stack extension to the small screw-in removable funnel, and then I slide the smoke unit in the front.  After it's in place, I screw the stack extension in from the stack.  The boiler screw comes up right in the spring, this keeps the spring centered, and the stack extension obviously keeps the other end in place.

This allows easy removal of the smoke unit for maintenance, and we all know that will be required from time to time.

Here's the Hotwart's locomotive with a fan driven smoke upgrade.

Thanks GR John, this is great advice, and the pictures make the placement easier to visualize.
