Well, I've gotten a lot done in the past few weeks. I made new frame pieces from brass for the side and end sills. I kept the steel bolsters as they were already done. The coupler pocket, drawbar pocket, and drawbar are done. I've started laying out the parts for the front steps on brass sheet. Todd

Got a few more parts in the works. Here's the parts for the steps. And, here are the steps all soldered up. I've started cutting one to shape. Also, the brackets for mounting the steps to the frame. More to follow. Todd

No pictures to show from over the weekend. But, I did finish making the center pins for the trucks and the drawbar pin. So now the trucks are officially attached to the frame. I can pick it up as one whole unit. And, it is starting to get heavy. Todd

Made some progress last night. The footboard brackets are complete. I test assembled all the parts, and everything fits together just right. Now I just need to clean all the parts and silver solder them. I hope to get that done today. Here's some photos: All the parts ready to start bending. The two on the right side have been milled to length and height. Drilling the end sill mounting holes. Drilling the footboard mounting holes. Test assembled. Test assembled on the end sill. The parts will be cleaned and re-assembled on the end sill as a jig during soldering. More fun to be had later. Todd

While I wait for the funds to buy the copper and brass to build the tank, I thought I'd go ahead and make some parts from the material I do have. I have some stainless hex bar to make the handhold stanchions on the rear end sill. Cut four pieces to an appropriate length. faced and center drilled both ends. Turned and threaded the lower end. Now I'm turning the diameters on the upper ends. After that I have to turn the taper to finish them. One piece at a time, right? Todd

I gave up Work for Lent many years ago. If you are ever in San Diego just give me a heads up before stopping by. I have a small shop and progress on my 1.5" scale A3 is a little slow now that I'm rebuilding the lathe but I did finish inside and outside facing of the tender wheels and the modified journal boxes, I'm using roller bearings with a grease fitting and seals.

Well, I've been able to make some progress over that past month or so. Work on the tender tank continues. I learned how to form copper over a wooden form. This part gets cut down the center to form the two sides of the tank. Here the part has been split, the two halves mounted to their corner frames and resting on the tender deck. I made a bending jig for the upper and lower coal bin frames. The forms are aluminum that I turned on the lathe. They have two sides. One forms a 0.75" radius for the lower frame. The other is 0.79" for the upper frame. Pictured here is the lower frame ready for bending. Here is the lower frame after bending. I annealed the brass before hand. And, I've annealed it again here in my fire brick box because I have some small adjustments to make on it. Finally, here is a shot of the Wheel and Cylinder castings. I just got these last week. Nice to have these parts. Keeps me thinking about getting to the locomotive. More fun to be had. Todd

Parts from this weekend. I made up all the frame pieces for the tender tank frame. This is all 0.25" stock. Now, I need to make up the sheet brass parts for the top and coal bunker. Todd

Didn't get as much done as I wanted this weekend, but some progress was made. Better than no progress. Managed to get the Verge board cut out, cleaned up, and bent to shape. Also, have the coal bin wall cut and marked for bending. Here's the wall: Here I created a template for the Verge Board using Autodesk DraftSight. I glued it on to the brass sheet. I couldn't find my 3M spray adhesive, so I had to use wood glue. Worked well enough. This is the Verge Board cut out using my scroll saw. Here is the Verge Board after being cleaned up on the belt sander. Verge board bent to shape and fit in to the upper frame. Still need to cut and solder the upper lip of the verge board. More fun to be had. Todd

Good progress over the weekend. I finished up the coal bin. It was all screwed together for these photos. The soldering is done, but I need to clean up the part. The sides also have their bottom members soldered now. I'll post some pictures when I get them cleaned up. Now on to the front and top panels. More fun to be had. Todd

I've made a lot of progress since my last update. The tank is assembled and soldered. And, now I'm working on the water hatch. It will be rectangular instead of round. The prototype pictures I have found show it as rectangular. More of the assembly pictures are on my Flikr account. Todd
