Here the cylinder is getting zoomed with a 5/16" reamer. The ID of the casting was such that all it needed was the reamer. Then the bore was polished with wet or dry, stuffed through a slot in a dowell and spun in the drill press. #400, #600, #800, and then a small piece of soft cloth and metal polish. The bore ended up with a mirror finish. It needs this as it must slide freely. Third and forth photos, turning the OD of the piston, and then drilling for the crosshead.

Now here is the whole mess. As you can see we have 10 Lbs. in a 5Lb. bag. Getting all this little baloney to work smoothly and not bind was what had me speaking Navy Language. You have no idea how many times I put this together and took it apart. Trim, adjust, put it together, use Navy language. Take it apart...Getting the little crosshead, .062" steel rod, to work smoothly in the crosshead guide and line up with the cylinder provided a few Navy moments. It all has to work effortlessly because the doors are closed by gravity alone. Stubbornness eventually paid off. The little rascal...will open with 10 LBS. of air, and closes with a satisfying "clink". Too much fun! The manual operating lever pivots a cam, that moves the crosshead to the right. The cam eventually goes over center and keeps the door open. One thing I hadn't thought of is that when the door opens on air, the manual lever and cam drop down and prevent the doors from closing. I hate it when that happens! I will have to come up with some sort of return spring and stop for the lever and cam to keep it raised when the door opens on air. This little fire door was a real gas to make. What shall I make next. Like a kid in a candy store.

Having been in the Navy, I can vouch for the practice. As Mark Twain once wrote: "Under certain circumstances, urgent circumstances, desperate circumstances, profanity provides a relief denied even to prayer."

I’ve heard it referred to as “Railroad Esperanto.”

Hello My Friends
Here is a shot of my messy shop. Where' the broom? The mess isn't what I want to show you though. So lets zoom in and see these hasps' and the little hinge. You saw the masters for these parts a while ago. Now that the castings have arrived I can put them together. They are for the full width turret casing and some will also be used on the tender tank. All this little baloney except the hinges is 1-1/2 inch scale from the old engine house model and has got me to thinking. It would be fun to build one to photograph the Hudson in. Someday when I don't have anything else to to :lol:

That coffee mug is a great touch. I'm surprised it's not coffee-stained, though!

Hello My Friends
Here are a couple snappies just for fun. The fire door is a bit oversize, but it will just have to do. It's propped up on a piece of wood just for a look. Now the question is, will there be enough room for a couple water glasses? I plan on making some water glasses that look like the reflex variety but will actually have a tube in them.

Post by Andy R »

Yes, It appears that there is room if the glass is mounted in front of the doors (not really in front, but further away from the backhead so the doors clear when open) and the bottom fitting is below the arc scribed by the bottom of the door.

they look awesome in the cab jack, even though they might be a bit oversized but to your advantage that's good cuz then it will be easy to get the grates in and out after each run. just remember to keep the gears inside the air piston lubricated, dad and I learned that lesson the hard way. but our new flip down door is fantastic. and from a scale look appearance you'd swear you were in a full size cab, most of the standard doors were big as well as the franklin number 8's. im a big franklin number 8 nut. :D :D
