Fantastic!!!. Great job done by all who helped. Thank you Eric for posting. (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)
Wow wow wow wow! Thanks so much to you and the group for all your hard work. You guys brought another one back and she looks and sounds great. Really smooth and might even have a little bark is she got a load to pull. The eames break didn’t sound that loud to me. I really like the extremely bent generator exhaust. As is the occasion wasn’t cool enough, You did an excellent job getting shots all along and editing that video as well. Thanks again for sharing it with us all and I really can’t wait to see it all in September.
Ya done good, every one of youse guys.
Was that dismal a Whitcomb? It reminded me of my New England days a half a century ago.
I swear I could smell the Tin Lizzy’s exhaust!
What a wonderful playground! I’m jealous!
Thanks for posting.

Very cool. Thanks to you guys history is now. Thanks.(http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)
GREAT SOUNDING Whistle… You did very very good. I’ll bet the grin is still there, and the cheek mussels still ache a bit.
Now is the time to except all the well earned accolades. You and the team earned a big well done. And every time you see a small kid wide eyed in amazement you will strut just a little taller, and a certain spot inside will forever know that you had a part in changing some kids life, if only a little bit.
WELL DONE!!
Thanks guys it is really cool to be involved in such a project! Hope you all come to Maine and stop in!
The little diesel is a Plymouth

Dave I think you meant to say …accept all the well earned accolades.
Very different meanings.
Well done Eric!

Eric,
I’ve visited many times in the last few years and I’m always amazed at how much gets done in a short period of time. I’ll be visiting a lot more in the near future since I’m looking at buying a house in Wiscasset.

Be great to have another large scale guy in the area! The WW&F is a great organization… Lots of interesting people and projects.

The loco just rests on the rear truck at the pivot point. safety chains keep it near in case of derailment. there is no radius bar which would only be necessary with one axle which cannot keep itself aligned.
It is interesting, the springs are pinned to the truck but the pivot just rests atop the hard point on the springs and the loco rests on that…no bolts!
Eric,
Forgive me for backing way up in this thread. But I love this little loco and wanted to revisit a few aspects since you really walked us through building a locomotive. I am still a bit baffled by the rear truck. I get how the springs are attached to the truck frame. Then there is the pad which has the rim on it. Now is it somehow dished on the bottom to fit over the top of the springs? As stuff is sliding around what keeps the pad centered over the springs since it is not bolted down? I get that weight holds it down onto the springs but seems it could still shift around if it was simply flat on the bottom. The there is the issue of the loco itself riding on the rim. Again weight holds it down, and chains keep it from flying off, and side to side movement is obviously desirable but what prevents forward/rearward movement of the truck. is there some sort of channel on the underside inwhich that rim is sliding that prevents movement front to back?
I can get that weight is enough to hold the loco on the truck but I just don’t understand what is keeping the truck in the proper position forward and backward.
Devon, I would think there would be a pin in the locomotive bolster that fits into the truck bolster hole.

I would think that also, but going on what Eric has relayed it just sits there. There is a hole in that plate begging to have something fitted in it. And that would make sense to me that some sort of a pin is inserted into the truck bolster that corresponds to a matching slot in the framework of the locomotive. that is what I am hoping to confirm. But looking at the pictures he has taken of the original frame I see no such place for one…
Paging Eric…You are need in the Lobby.
of course this is merely academic, because I no interest in modeling this.
Great video Eric.
Now, when is Accucraft going to deliver that SR&RL 0-4-4 in 7/8n2 scale . . .

I had a thought. Then I thought again and didn’t.

The casting between the springs and the bottom of the Loco also has sockets which accept “bosses” which are part of the spring assembly. In the photo of the truck you can see two “webs” which make up part of the sockets for the springs. That casting stays put on the springs… Can’t move with the Loco sitting on it.
By the way yesterday’s work session required jacking up the rear of the locomotive to pull out the truck. We needed to add a couple of shims as things were a little tight back there. A couple of screw Jacks did the raising. The hardest part was dealing with the brakes… Lots to undo and do up again.
Unfortunately, I didn’t get shot of the casting in question. I hope I helped you understand it a little.

OK you confirmed half of what I was wondering. I could see the protrusions on the springs and how that would corresponded to a socket (or sockets) in the casting underside.
Now with that casting setting on the springs I can see how the weight would keep it in place. But the second half of the question is what is going on between that casting and the loco? I can see how the loco sits on that round doughnut portion of the casting. But what is that doughnut sliding on and what is preventing the truck from slipping out the back end when the loco goes forward (or the opposite in reverse)? It seems to me that one of two things has to be happening at the casting/locomotive interface. One that doughnut is riding in some sort of socket itself which allows it to move side to side but not forward and backward, or a pin is being inserted in that hole in the casting that then protrudes up through a slot in the loco frame that allows side to side motion but retains its position forward and backward. I would think something closer to the first is in order. A pin seems like it would be weak and would want to shear off (and you said no bolts). The other way having that raised doughnut sliding in a channel would make sense to me as it would just rely on the wright of the loco to hold it in the groove.
Edited because maybe I am stupid??Well we know that. . .but anyway. Another thought I had is, is this truck not sliding in any direction but instead has a pin that is fixed to the loco frame and then the whole loco is dropped onto the truck and the pin in the loco bolster goes through the hole in the truck casting like it would on any other regular car? This is where you were going wasn’t it David? This all of a sudden makes sense to me, so I hope I am right or at least close. For some reason I was hung up on the need for the truck to pivot side to side. But it wouldn’t need to would it? It can stay in a fixed position centered under the tender portion, correct?
Please tell me the lights just came on
I imagine there is a round boss that sits in the circle, there has to be some pivot for curves while the swing hangars take care of lateral movements.

Oh buddy yeah…
