Re: Steam railroading to return to Alaska!
Another photo from today by Terry Douglas captures both the engine and tender. The building is way too small to get a good side elevation.

Re: Steam railroading to return to Alaska!
I paid a visit to Wasilla today. Almost all of my volunteer work (book keeping, grant writing/fund raising, and publicity) is done from home. Avoiding covid, the 100 mile round trip, and some health issues have kept me away for about six months, I had to see what 557 looked like in person with the wheels on and the tender pushed up against her. Take my word for it, she looks awesome.

Like! Because there is no button.
Live for the moment!
Prepare for tomorrow!
Forgive the past!

Re: Steam railroading to return to Alaska!
A new monthly status report It has been posted at https://www.alaskarails.org/pix/former- ... index.html
While the rest on of the crew has been doing hands-on work on the locomotive, I have been working from home and my free time for my personal modeling was again commandeered for building full sized locomotive parts.
We needed three more 3" diameter Pyle National 32v DC electrical plugs for the cab and none could be found. Lacking a source for OEM items I decided to fabricate a few.
The originals are in the upper left and left of the photos. The original case is die cast aluminum, but the replacements were sand cast. I tried several times to use the original as a pattern, but the lack of draft prevented it. Then I made a 3D printed pattern, which did the job. I didn't see any future in bending the contacts from 1/16" brass as was done on the original so the new ones were 3D printed in castable resin and investment cast in bronze. The replica insulators were 3D printed using a resin that will withstand 320 degrees, higher than the original Bakelite.
I hadn't done single point threading on a lathe for a long time and I don't think I ever single point threaded an external or internal thread to a shoulder. It was a slow process, but no crashes, life is good! Being able to slow the lathe way down with a VFD made it a lot less stressful.
If I were to do it again, the cases would be 3D printed and investment cast . It would have been more work and cost more for supplies. but multiple set ups and a number of hours of machine work would have decreased to a single 1" - 14 tpi thread and two holes drilled and tapped 6-32.

Speaking of Pyle National electrical covers, here’s what a friend repurposed as the tender water hatch on his live steam loco.

Re: Steam railroading to return to Alaska!
Fender - did you open the hatch to make sure it it wasn't the charging port for an electric locomotive?

That’s what it looks like, but there’s only water in there!Dick_Morris wrote: ↑Thu Jun 02, 2022 11:35 am Fender - did you open the hatch to make sure it it wasn't the charging port for an electric locomotive?

It's surprising that just when a need arises, the solution walks through the door. Last month a new visitor took the Engine House tour. When we learned he was a sheet metal craftsman we asked, and he agreed to help with fabricating the new jacket and other sheet metal parts. In the photo, Project Manager Patrick Durand does a trial fitting and measures for the door in the side of the newly made cylinder jacket.
