A first live steam loco
« on: April 13, 2021, 03:06:23 AM »
I'm a new forum member and at the urging of those who've welcomed me I thought I'd post a few pics of my first crack at building a small live steam locomotive. This was completed about a year ago. I worked from Mr. Dave Watkin's plans for his Wild Rose III.  This is a 16mm/ft scale model of a British 2 foot narrow gauge quarry locomotive. The drawings are publicly available at the 16mm.org.uk website and are very good; complete, clear, and without errors.

I followed Mr. Watkin's drawings pretty faithfully for the chassis and all the steaming and running gear. Where I deviated was in building the cab, tank, details, etc. to 3/8" scale (1:32) and to resemble the early logging locos built by Baldwin and others. To my knowledge none of those were built with outside frames, but I figure since it was a time of experimentation and make-do equipment, someone might have! At this scale the 32mm (O gauge) track corresponds to a full size gauge of 3ft 4in.

Regards,
Ron

Thats a great looking loco, I like the proportions. Is there a control for the reverse, or do you just roll the engine back so the drive pin moves around to the other stop?

Say now, that is a pretty slick little garden loco. I like the design changes you made.  :ThumbsUp: :ThumbsUp:

Alcohol version, I presume? How does it run?

Very cool!  And you've got an elevated track running around your yard? That's really neat!

Thanks for all the positive feedback! I'll try to answer your questions in order.

It uses slip-eccentric reversing, so yes, you roll it by hand a rev or two to set the direction. Simple and practical at this size. (And congratulations, crueby, on your new column in Live Steam. I enjoyed the first one and admire your work!)

Yes, it is alcohol fired. There is a butane fired fired option, which would require a different boiler. Overall I like the simplicity of alcohol firing, although I admit the rate of steam production doesn't quite keep up with demand. Apart from that it runs quite well and will do a few laps of my little loop of track before needing a breather (the full size Elk River Mill & Lumber Co. #1 "Falk" has much the same problem:}). First attempts at running only went about 6 feet, so I've been able to improve on that quite a bit. Most importantly I've learned a lot.

"Elevated track running around the yard" is true enough but sounds more grand than the reality! My yard is quite small, but has two raised garden beds of about 3.5' x 6" each with a couple foot gap between. The track runs mostly around the rims, but reaches out to the fence at one end, then crossing back via the "stone viaduct" visible in the last pic. The tightest curve has a radius of only 18", hence the need for a short wheelbase.

Ron

My first ever in the history of the universe YouTube video. I hope I don't trigger a second Big Bang.

The video is there, but it needs to be made public or at least unlisted - it is currently 'private' so only you can view it. Just change the checkbox on your youtube page for that video.

Very nice video!  Thanks for posting it.  Seems you fixed the permission problem, or at least I can see it :)
