And the latch spring size will determine its mounting location. That's how I set up both my locomotive Johnson bars. Unless...

Re: Cylinder Borning

I have bored a long (6") cylinder on my mill using the power feed knee for the vertical motion. It worked perfectly. I also machined the cylinder set for my Mikado on a tight DRO-equipped Bridgeport mill. I milled the saddle and mating cylinder flats, Bolted the three pieces together, and secured th...

Just make sure it all certified hose for propane. you can tell by the outer cover it has a million holes in it.
I had my propane hoses and connections made by a Propane Supplier Company.
Fortunately it was a small business happy to make custom items.

The boiler is a mess...
