Re: 1.5" SP A6 Atlantic

For your brackets you basically just welded 2 pieces together forming the "L" shape, then the brackets themselves have no clearances milled in for the piping? with the clearances only formed in the brass from the pressing? Truly looks great! Is your power reverse dummy or working? No the ...

High quality SP drawing scans

As a side project to my Southern Pacific A6 Atlantic, I've been collecting original Southern Pacific drawings that apply to other locomotives as well. In my opinion the key to preserving these pieces of history is in digital copies that can be distributed easily and protected against dirt, water and...

Re: 1.5" SP A6 Atlantic

Here's a shot of the reinforced structure and a comparison to the original LE casting. IMG_0110.jpg IMG_0111.jpg Because the steam pump is designed for the fireman's side, I'd need to plumb everything backwards, which would require air brakes, power reverse, cylinder drains, injector water line and ...

Re: 1.5" SP A6 Atlantic

Looking good however I would be concerned about the way your steam trap pigtail is piped. To keep the steam out of the gauge it should be piped under the it. These are just mocked in place currently, but I will modify the design to have the pigtail at the bottom. For mounting the turret cover, you ...

Re: 1.5" SP A6 Atlantic

Those are absolutely beautiful booster details and as soon as I can figure out how to stuff all of this other plumbing on the model, I want to try to incorporate them. Jack was gracious enough to lend me a hand with creating new forms for the copper boiler backhead sheet. Being my second time, it di...

Re: 1.5" SP A6 Atlantic

Sounds like a good bet for Anthony Duarte's skills. Would be nice. I've pitched the idea to him once or twice :) With the inclusion of the booster exhaust pipe, does this mean the trailer truck may be sporting a dummy booster when completed? I have considered this but concerned about necessary plum...

Re: 1.5" SP A6 Atlantic

The feedwater heater is 3D printed from a beautiful model designed by chaski member Fltenwheeler. The model pictured is just a test run with basic PLA plastic while the final version will be printed in resin. I'll have a detailed writeup about the model in the near future.

Re: 1.5" SP A6 Atlantic

Next up is jacketing. I started by cutting out paper patterns for the different courses. IMG_2648.jpg Then cut several 1/2" strips of 26 gauge sheet steel for the boiler jacket bands on my friend's large shear. IMG_3705.jpg And drilled and tapped some 3/8 angle I had laying around and silver so...

Re: 1.5" SP A6 Atlantic

Moving forward, I decided to work on the firebox wrapper side sheets. I created a simple rivet pattern jig on the mill, and used it to lay out the copper head rivets along the edges. I believe 3/32 sized pop rivets were used for the hollow stay bolts and 2-56 acorn nuts for the flexible stay bolts. ...
