This low-resolution picture was on 'Google Images', no idea where from, it didn't say.

Si:

I missed this one.

The more I look at the drawings and photos, the more I am drawn to this little engine's lines and proportions.  

I will see what happens when I try and print it larger.  

The MR back issue with the drawings will be arriving in a few days, too.  I am anxious to see what those drawings look like.

Much as I am fired up, I have a few projects ahead of this one (if I decide to do it).  In the process of moving shop equipment around to allow for the installation of a new garage door (boy! Is that a serial story) the cross slide knob got broken on the little Atlas lathe.  Since I am giving that lathe to a friend (soon), fabricating a new knob is high priority.  It is almost done.  

Then I want to get back to the horizontal mill engine I am building.  Somewhere in there I need to build the boiler so I can run the mill engine.  Though I will probably do initial testing with compressed air.   I have a PM Engineering kit for the boiler.   It is a real live fire tube boiler, so it will be a substantial project.   I will have ample opportunity to relearn silver brazing.   

In the dim and distant past I used to assemble loco frames per Mel Thornburgh methods, but I brazed (silver soldered) them. Mel used 60/40 lead solder.  I also used to cut loco frame parts using a jewelers saw and files.  It took many, many hours just to build one frame.  In a five year period I only built three locomotives.  I have photos somewhere, I hope.  The locos themselves got sold in the process of going through a divorce, along with a lot of other 1/4" scale stuff.

Not now.  I have a complete machine shop.  What used to take weeks should only take a few hours.  

I am concerned about drivers.  Precision Scale has 42" driver centers.  I don't know whether those are 42" driver centers, or centers for 42" drivers.  If the former, they would work for 48" drivers.  But not if they are the latter.  If and when this gets serious (and it gets more serious the more I think about it) I will talk to the good folks and find out the exact spec.  They also do custom casting, so that might be an option.   I can fabricate all of the parts for the engine, but fabricating driver centers is a tedious business. 

In the old days there was a lot more available in terms of machined and mounted drivers.  I have never machined drivers.

As I sit here and type this, I am thinking about one more project theoretically ahead of the Little River.   I have the castings for a Stuart 10V vertical mill engine.  I just may box that project up and put it aside. 

But the horizontal engine and the boiler must be done.  If for no other reason than I have a tendency to accumulate half-finished projects.  

I just want everyone to know this is an evil thread.  I was not intending to dive into a locomotive project quite yet.  Let alone a mallet. Scratch building model locomotive parts is really not that difficult.  Really! But even a very simple locomotive is a pretty big project in terms of the number of parts.  Start thinking about all the parts that go into Walshaerts valve gear.  None of them are particularly difficult to fabricate, but this locomotive has four cylinders!!

That's 40, or thereabouts, separate components.  Given the shop time I have available, that's between six and ten weeks of work. 

OK.  Now I have to get some work done.

After you build the Little River 2-4-4-2, you could tackle a NG ALCO 2-4-4-2, used in New Zealand on the TTTLCo a
3 ft 6 Inch line. I have a set of plans I will take a look for and post.

That is a little sweetheart.  

I downloaded the information and put it in my "possible future projects" file.  

But who knows when.  I figure I am out six to eight months on the current project.  The Little River Mallet is probably a two-year project.  Call it two-and-half years if I have to scratch build the drivers.  

There are quite a few intriguing little logging mallets in the world.  

By the way, here in the Pacific Northwest there were logging operations that used steam dummy engines off the old Portland, Oregon street railway system.  It was 42" gauge.  Around here that gauge was known as "bastard gauge".  

I need to look up that Jon Davis guy.   He did the drawings I found for the Little River loco, too.

Re: 48" drivers - The EBT's late Mikes all have 48" drivers. You might scrounge around for drivers from either the Sunset heavy Mike or the Hallmark medium Mikes (Nos. 14 and 15).

I love those 2-4-4-2's! On the Hallmark drivers, when I worked for them in 2000, the EBT HOn3 and On3 parts were long gone! Maybe a search on fleabay will yield some.
Good luck...

I betcha 'Alan Gibson' in the UK would have something suitable.



They make very nice wheels.



Steel tires on moulded centres & their own axle system.

Good idea.  There is lots of stuff available in the UK that we don't have here in the US in terms of parts, supplies and tools for the craftsman.  

I do a lot of shopping for machine shop stuff in the UK.  Sometimes a bit of a pain because not all the companies are thoroughly organized to do business outside the EU.  And sometimes I pay more for the shipping than I do for the product. 

When I was shopping for lathes my first choice was a Myford.  They are rare as hens teeth on this side of the pond, but quite a selection of nice second hand lathes in the UK.  But shipping was cost prohibitive.  The cost of crating and shipping a 600+ lb item across the pond, and then across the continent, contained far too many places to the left of the decimal point to make any kind of sense. 

I am quite happy with my Clausing 12" (it would be classified as a 6" in your hemisphere. In the US lathes are sized by the diameter of the swing, but by the radius in the UK) but when I see You Tube videos with guys using Myfords, I get a twinge of jealousy.  I guess it would be about bragging rights.  My Clausing spindle run out is something less than 2.5 10,000ths of an inch and the controls are like butter, but still.....

If and when I get around to this project (or one similar) I may tap you for information on sources.  If you don't mind.

My back issue of Model Railroader came yesterday with the Little River 2-4-4-2 plans. 

The article (March 1962) is great, with lots of photos.  Kinda funny, though, I remember having this issue when I was a kid.  I would not have flashed on the Little River article because I didn't meet Charlie Morrow and start going up to Snoqualmie until the following the year.  Or maybe even the year after that.

But I sure remember the article about Clouser's electrics.  This article, along with others featuring Bob Hegge's Crooked Mountain Lines, have kept a "back of my mind" interest in heavy interurbans since my teen years.  

I have always thought of my building interests being tied to my layout.   Since I don't really have an interest in building a logging themed layout or an interurban themed layout, projects like the Little River 2-4-4-2 and interurban equipment have always been back-burnered.  

As I build a pretty much RTR HO layout, but now have my machine shop, I am moving away from that mind set.  Even to the point where my current machine shop project is not railroad related.  

So the Little River is definitely going into the Future Projects file.  Almost certainly along with some thoughts on heavy interurban equipment.
