Re: 0-6-0 L9 Switcher, differences

Curtiss, if I was building a narrow gage steamer I would build a K36. I like the unique factor of the drivers being inside the frame yet the counterweights and linkage on the outside. Also, I think they look great with those big snowplows on them:) In 3" scale one would be huge though, would bet it ...

Re: 0-6-0 L9 Switcher, differences

I did a google image search and found a bunch of pictures online, I'll post them up this week. That's correct Curtiss, it's the same locomotive with the exception of that forward wheelset being evenly spaced where many of the NP 0-6-0's had it further forward, and the various tenders and fuel source...

Re: 0-6-0 L9 Switcher, differences

I'm drawing the parts in AutoCAD LT for a "someday" build that will be mostly laser cut and fabricated plate, and pipe of course.

Re: 0-6-0 L9 Switcher, differences

Bumping my old post. I am still drawing parts for this 0-6-0 in 12" gage(2" scale) as I have a few minutes here and there, what would I want to do/use for the "petticoat" for this?
I pretty much have the linkage figured out, and looking at a 2-3/4" bore, 5-1/4" stroke inside 6" long cylinders.

Re: Driver machining order

I don't think it's "bend" in the mill table, but as you move away from center in the X-axis direction the heavy end sags. So I'll indicate the area I'm working in, and either tram it in or remove the vice from the center. Last time I got lucky and it was right on in an area about 12" wide, left of t...

Re: Driver machining order

I have always turned wheels on the lathe, boring the axle hole without removing the wheel from the lathe. The crank pin holes get drilled/bored on the mill using a fixture for accurate alignment. RN This is how I'd do it. Make sure your mill head is trammed in so its nice and flat! Our mills at wor...

Re: 730 Gets a Boiler

That's quite a difference, I'm amazed that it was even possible to see such a big gain but like anything the extra tubes, insulation and probably a better firebox shape and size all add up!

Re: 730 Old Boiler Dissection

The upper portion of the tube sheet is pretty much gone. It corresponds with being the hottest area of the boiler. Could be a good case for making the crown and tube sheets on the firebox end much thicker in future builds, even if one has to add a few more tubes to offset the loss in heat conductio...

Re: New Puget Sound Live Steam Club

12" gage would be narrower and cheaper, stable enough IMO for single row passenger carrying. :wink:

Re: 12" working railroad

Thanks Glenn, I'm amazed I've topped so many views. I finally found some 19 tooth sprockets in 520 chain size, they should be here today so I can finally weld those to the hubs for the hydraulic motors and then start assembling the powertrain into the S12's trucks. I bought two of these Brevini hydr...

Re: New Puget Sound Live Steam Club

I'll bring my kids down for a ride when it's operational :)
The original ROW's were around 14' wide right? So if you had to share part of the ROW with pedestrians on the trails would it really be a problem only needing a 3-4' wide ROW?
You going to make the yard goat into a SW1200 +/- ?
