Re: 0-6-0 diesel yard switcher

Then you have all the advantages of an 0-4-0 with the added traction of an 0-6-0.
Everything I've read says the weight on the drivers is primarily what affects traction. Adding wheels without adding weight shouldn't make a significant difference.

Re: Southern Pacific Blueprints

Norfolk Southern Historical Society also has a number of suppliers' accessory drawings that were redrawn by the RR for their internal use.

Steamtown has an extensive collection of Nathan drawings.

Re: Steam railroading to return to Alaska!

With adequate funds we could do steam tests late next year and operational tests the following year. Without adequate funds we will work on it at a slower pace.

Re: Steam railroading to return to Alaska!

September was a very busy and productive month for the Engine 557 restoration. Test fitting the accessories on the backhead is just one of the accomplishments chronicled in the the most recent status report. It, and previous reports can be reached at http://www.557.alaskarails.org/restore/index.html.

Re: USATC S-160 Consolidation

Glenn - The short answer is yes. I have two 3D printers which use different technologies, both bought within the past three months. (These things have become unbelievable cheap - I paid about $275 each. The total cost for both was $100 less than I spent on my first dot matrix printer 35 years ago.) ...

Re: USATC S-160 Consolidation

VOG has been at it again. This is what he did with the 3D drawing we used to make a replacement builder's plate for the prototype Alaska Railroad #557. I got a copy and sent it to him and this is what his efforts produced at 1/8 scale, 1.125" diameter. He has a video of it being produced at https://...

Re: Modified D-valve dimensions from print

Just thinking - I I were to use the "sandwich" with the steam chest holding the plate in place I might use a couple of taper pins or tight fitting rust proof pins to ensure that the plate would return to the same location if it moved when the steam chests have to be removed.

As a comparison to a prototype, 57" driver tire for a WWII USATC S-160 Consolidation. .065 interference on a 51" center.

Re: USATC S-160 Consolidation

My second and third attempts at lost PLA casting. The door dogs, only 5/8" long, came out well. The only finishing work required was to open the cast-in holes by about .010" and use a belt sander to remove the sprues. This was my second attempt at the crosshead casting. The mould cracked on the firs...

Re: Need source for graphited yarn for packing

Is this what you are looking for? It's supposed to be in stock at my local Ace hardware.

Re: 730 Gets a Boiler

This has been an interesting discussion, both the boiler replacement and the side discussions. I did a quick Google search. Apparently, combustion products of natural gas can result in small amounts of acid in the condensation. That would encourage corrosion. This paper is over my head, but the Engl...

Re: Power reverser for small scale loco

I believe that Baldwin took over the Ragonnet design and marketed it under their own name. I have a 30 page instruction book on the BLW gear if you are prompted to kit bash the Modeltec drawings.
