Large Scale Central

Rebuilding WW&F #9

Prototypes
#101

I am probably wrong, but looking at the truck, and the way the internal springs rides on the ends of arms that are mounted with rods at the top of the truck, it appears to me that the lateral movement of the truck is handled through the arms, rods and springs in the truck. So the pin, or whatever, on the locomotive frame could be in a fixed position. The king pins on boxcars are fixed, and not bolted to the trucks. But boxcar trucks don’t have to swing side to side, hence all of the extra linkages, rods and springs in this truck.

In reading in the Carchism of the Locomotive, on page 317 and 318, the operation of the truck is explained the way I though that they worked. “The lower centre-plate is usually suspended in some way from the truck-frame on links or hangers, so that it can swing laterally.”

I do get that lateral movement is taken up with the glider rocker mechanism. That should swing side to side enough to compensate for any lateral movement. But it still really isn’t addressing how it is keeping from moving front to back. I do think that some sort of pin has to be on the locomotive that slides into that hole.

Eric will clue us in sooner or later.

If you look in the center there’s a flat bearing, if not a pin extending from the opposite bearing face then it’s a nubbin. I see no signs of wear in the outer dirt catching ring, so yes it’s centered on that bearing.

But mebbe like badges we don’t … then again I’ve been waiting 65 years for a clue.l(http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-tongue-out.gif)

am beginning to believe that I will forever be cluless

#107

Awesome! What a beautiful little loco! I like that railcar too.

#108

We spent a lot of time getting both engines ready for the Victorian Christmas celebrations last weekend. Here are Numbers Nine and Ten building up steam on Friday.

this is called “sparking” it is using a steam jet to eject the ciders from the smokebox Hasn’t been seen around these parts for generations!

I graphited the smokebox…graphite powder mixed with linseed oil rubbed onto the hot steel. protects against rust and looks good too!

The boiler jacket is shiny “blued” iron rubbed with light machine oil.

the headlight is bright!

Running around the train

Jason gave me a cab ride and had me blow the whistle for all the crossings…(http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif) Great fun!

#109

That’s a sharp looking engine. You guys done good!

#110

She is beautiful. In this shot you can really see how tiny she is.

#111

I can wipe the entire boiler jacket while standing on the ground. Yep small compared to most any other engines and gauges.

#112

Eric, I like small engines. To me they have that underdog look to them. You are a lucky man to be able to work with such gems as them.

#113

Great pics. I like that side shot which highlights the boiler jacket.

Was the stack graphited too, or painted?

#114

The stack is painted… Time will tell how that works. It is actually double walled with an air gap… Thus shouldn’t get too hot.

#115

Well with #9 running well and able to pull her weight, it is time to give #10 a look over. She is due for her 15 year inspection. this includes ultra sound inspection of boiler steel thickness and possible tube replacement.

The first thin that was done was to remove the boiler jacket to expose the boiler shell. ultra sonic testing involves polishing a spot and placing an ultrasonic transducer right on the metal. thickness is found also (with more sophisticated equipment as we had) voids and cracks can be seen. This boiler was made in 1960 by a contractor for Edaville Railway in southeast Massachusetts.

WE found cracks and issues around the staybolts which hold the firebox inner shell and the outer shell in position against boiler pressure. We decided to flame cut out one stay bolt to study.

this is a blown up photo showing the welded joint between the staybolt (horizontal in this photo) and the outer boiler shell (vertical in this photo) You can see a void and a crack in the welded area. this is unsafe and will require fixing. the boilers made by this company have tended to have this problem so we were looking for it. We will remove the weld and staybolts and replace and reweld.

Today we lifted the boiler off the chassis and moved it into the shop so work could commence.

above the boiler is lifted and the chassis rolled out from under. below the boiler is being pushed into the shop…the chassis and caboose are basically serving as an idler car

#116

thats a cute little thing

#117

So we begin yet another great journey " The rebuilding of WW&F #10 "

Looking forward to this!

Thanks Eric!

David,

I agree. I love these little engines. Some people are drawn to the big behemoths for good reason but man there is just something special about these little locos. I am basing my indoor on tiny locos in part from the inspiration from this build. I think a narrow gauge mogul as being big (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)

#119

She is a pretty little engine! we hope this is not such an epoch project as #9 was and hope to have her running again by the September National Narrow Gauge Convention

#120

This is a FRA mandated 1472 inspection, Right? How many tubes in the boiler, can’t be that many on such a small boiler, and what size are they?
