Hello My Friends Here are some photos of the pot belly caboose stove for the bobber caboose. Here we have one of the pot belly bodies being drilled for the ribs using the spindex. Attachments:

Here we have a tapered piece of brass that will become the ribs. It tapers from 1/16" on one end to 1/8". Attachments:

Here the rib has had the edge rounded using the belt sander. Attachments:

And now the rib will be sliced off with the milling machine using a saw blade. Attachments:

Here the rib has been drilled and annealed and is now being curved using a piece of round stock and the rubber mallet. As the process of forming the rib with the mallet will work harden it and it doesn't fit the pot belly body perfectly, it will be annealed again and then go for a swim in the acid pot so as to be nice and clean for the soldering to come later.

And now we are getting somewhere. Here the ribs are being attached to the body with tiny screws. After soft soldering, the screws will have their heads filed off. Attachments:

Here the ribs have been soldered and the door frame has been roughed out and set in place for a look. Attachments:

Last one for now. The door still needs to be made along with it's hinges and the rotating draft adjustment door and latch. Also still to be made is the base of the stove. Some stoves had round bases and some were square. I haven't decided which sort of base to make but it will have an ash removal door with sliding damper control and more pesky ribs. No shortage of things to do! Jack Attachments:

Jack I know someone here who puts a lot of details on his models and I thought that he was the best I had seen until I saw your work ,your work is magnificent , I always read and look at your threads and enjoy them . Keep up the good work , I am sure every one on this site enjoy your threads. I may only comment every now and then but I always follow the progress and am very impressed .

I'll second that! The workmanship is simply wonderful - I bet that the stove will work as well  I used to get completely disillusioned at shows when I saw the quality of work and wealth of detail some builders can achieve - now I delight in what others can achieve and hope that my own efforts will improve a little. Thanks again for posting Q |

I dont know...I really cant work what is more astonishing  the machining skill or imagination to work out the process steps Either way, I like seeing the thought steps that are needed to gt to the end |

Hello My Friends
Once again thank you for the very generous complements. Thinking of something like this as a delightful little puzzle is always helpful. Sort of a 3-D chess game. Think in terms of shapes and how to achieve them with what you have laying around. Some model builders that are skilled with computers and CNC machining centers would do it differently. I'll post more photos soon.
Jack

Hello My Friends Here are some pictures of progress on the caboose stove. In this photo frogs are being used to hold the hinge in position on the door frame for silver soldering. A bridge was left between the two parts of the hinge to maintain alignment of the two halves. After soldering the bridge will be cut out. Attachments:

Here is the stove as of tonight, mostly done. The screw heads have yet to be filed off, some metal finishing has to be done, and there are two truss rods that go from the top through the central ring and into the base. There also will be a little handle that will be used to lift out the round plate in the top. Almost done, quite a fun little project. Next up will be some tiny oil lamps for inside the caboose. Not real oil lamps, as they will be electrically operated. One over the conductors desk and one down the other end of the caboose over the bunk. The wiring is already in the walls, you have to plan ahead. Happy Model Building Jack Attachments:

Jack,that is more like watch making than model engineering.When your caboose is fimished,I think it would carry off a first prize wherever it was exhibited.

Hello My Friends Thanks Phil, the caboose has been a fun project. The stove is finally done so here are a few last photos of it for now. The last piece to be made was this tiny handle to lift out the plate, another little puzzle. Attachments:
