Finally in blue paint and decals. I have some touch up to do and still need to add a few details.

One other item I’m going to add. This photo shows a shield over the headlight that matches my prototype.

I think I’ve got worked out how to replicate it and will be adding to the finished model.

Updating a little more progress this week. Not a lot to show. I was working on the grab irons and it was one of those times when nothing you do goes right.

So, I quit for a few days and came back to it. I finally got them in place like I wanted. I was able to add the lift rings to the hood also. Next time I have a picture it will be in blue.

There is a list of MoPac related articles on the Modeling Resources page by Bill Herbert that includes many from the Eagle magazine.

I’ve been working on an article index for the Eagle, but I’m still missing quite a few issues. The file is in Excel format and lists the main articles from the table of contents in each issue.

You can never have too much reference material. I don’t mind posting a copy here if anyone would feel it’s useful or would like to help complete.

Thanks Charlie. I haven’t decided yet if the speaker is going in the fuel tank or in the cab.

The cooling coil set is another 3D print. It took some trial and error before it looked right. Sometimes I’ll do 3-4 test prints before it works.

I also got the exhaust manifold mounted on the hood. This shell didn’t have the correct headlights so I’ll be modifying those to the correct type.

Charlie – In know you wanted to see Cannon fans but I went the cheap route here. I had picked up a Proto 2000 GP-9 shell at a swap meet for parts. These are the fans from that shell.

Slow progress this week. I spent too much time on this cooling coil assembly and finally got it how I wanted.

Here is the big issue so far. In this image you can see the layering in the curved surface. It would sand off easy enough but not with the rivets in the way. One bright spot are the filter inserts. These actually turned out really close to the prototypes. I haven’t given up yet. There are a number of measurements that are off now that I have the print. I might scrap the curved hood and just print the sides.

Not to get off topic but I wanted to show some of the limitations of 3D printing. MoPac had a number of the Phase III locomotives and I would really like to have a couple without trying to find a Stewart shell or waiting on Bowser. I hoped to draw a replacement for the long hood on the Bachmann model. Here is a very early test print.

I also sprayed some primer on the body shell. I think the fan box looks good. I printed the MU hose storage pockets for the footboards. Still some finish sanding to do where I removed some of the detail.

I was able to paint some blue today. Here is the finished fuel tank and the chassis back together. There is a small cooling coil that mounts under the walkway on the right side behind the air tank. Still working on that detail.

[lenaculbert50]

I made the opening a little smaller than the fan box and used a needle file to get the fit correct. The resin prints are a little tall so I had to sand the base down to the numberboards until it fit like I wanted. I was happy to see the width was very close for the shell.

The pictures I’m posting could be better. I’ll try to get some clearer images as I go forward in the build. Probably last post for today. I have to wait for putty to dry on the old exhaust.

There is a company that makes the cooler frame that hangs under the walkway on the right side. I found them doing research but going to have to look into it again. If I remember correctly, it was a brass casting.

My paint booth is a little cold right now so moving from the frame to body shell. I had to strip Great Northern paint from the shell so still a little color left. I removed the exhaust stack and some of the smaller details not needed. I also made the cuts for the new radiator fan box.

[lenaculbert50]

I was able to add mounting holes for the Bachmann air tanks so I’ll be able to add them back after paint.

[lenaculbert50]

After some measurements, I drew a 3D model and printed the replacment tank in resin.

It’s difficult to see the detail in the clear resin but I was able to add the drain plugs to each side of the tank. I kept, and added the speaker holes but not sure if I’ll mount a speaker in the same spot.
