Hello My Friends The little American will need something to follow along behind, and as it will be some time before the copper boiler arrives this seems to be a good time to start the Bobber caboose. Early cabooses were often of the two axle variety and were notoriously bad riding little devils. Here is a photo of an early caboose very much like the one being built. Attachments:

Here is a drawing of the same caboose, sometimes called a crummy. This was a very early Pennsylvania Rail Road caboose. Unlike the model being built it has no roof overhang over the platforms, which was very unusual. Attachments:

The first parts to be made will be the masters for the axle boxes, the pedestals, ( I believe you chaps call them horns and horn blocks ) and the equalizer fulcrum and equalizer. Here is the start of the axle box, at this point just a lump of brass and a drawing. Attachments:

Just a little scribbling with the Sharpie at this point. The sharpie is a wonderful visualization tool. Attachments:

Now all that remains is to machine away everything that doesn't look like an axle box. Attachments:

And the start of the pedestal. This will be the bit that the axle box slides up and down in. Attachments:

As two pedestal cheeks will be needed they are both cut at the same time and will be separated later. Attachments:

The pedestal cheeks have had the outside profile cut using the band saw and is now being finessed with a drum sander in the drill press. Attachments:

Hello My Friends Thank you Shawki, I am blessed with some wonderful clients that allow me to make delightful little puzzles like this caboose. Here are a few more photos of what I have been up to. As mentioned earlier this caboose has an equalizer and some rubber spring-dampeners. The equalizer has a cast fulcrum in the middle that bolts to the caboose frame. Here is the start of the fulcrum. Once again some scribbles, some free machining brass, and silver solder. Attachments:

Just getting started, I don't think I would be able to function without my extra fine point Sharpie. Attachments:
