Building a 1:20 Mikado

Modeling

A few days ago, I put two pieces of solid 1/8" square brass through the boiler to act as supports for the air tanks. These were glued in place with JB Weld and left to dry. Once dry, I drilled 2 holes in each end. The hole furthest from the boiler is tapped for 0 90 bolts. The hole closet is drilled for 0 90 clearance. I decided to go ahead and paint the air tanks; they’ll get another coat when I paint the locomotive, but I wanted to make sure that everything was covered with paint. Running boards were cut from .060" styrene. I fashioned some steps from brass and bolted them to the front of each board. I cut some 1/8" x 1/64" brass strips to hold the air tanks in place. The styrene running boards were laid across the brass supports and used 0 90 hex head bolts and nuts to attach the brass strip to the inner hole.

The brass strip is wrapped around the air tank and slipped in between the running board and the brass support. A 0 90 hex head bolt holds it in place. Tapping the hole made it a LOT easier than trying to attach a nut to that bolt. (Yes, this IS the other tank.) :wink:

The brass strips hold the air tanks tightly and I haven’t even had to glue them in place. The hex head bolts look right at home on the top of the running board.

Krylon has done something to their paint; it seems to go on smoother than ever.
I know!!! Love the stuff!!

Very nice. The level of detail on this build is amazing.

I know....this is why Shawn,Cale and the rest of the "Young Crew" are planning to roll him at ECLS and swipe the unit! :)

Thanks, guys. It’s REALLY nice to have the support here. I need to thank Gary Buchanan who has really provided a lot of information to me in chat. Also, many thanks to Pete Thornton and Jon Radder who have supplied me with some nice detailed pictures. I did the hydraulic lubricators today…

Then started work on the steam turret. None of the pipes are connected, I just threw some up there to see what it would look like. Still need to build the generator.

It still needs a bit of clean up, but I’m really happy with how it turned out.

If I haven’t said it before, let me say it now…you are a true craftsman!!

#410

Hahaha. Thanks, but I’m not falling for that one. :wink:

I went to the Cabin Fever Expo last weekend, and I returned truly humbled. The level of modeling there was simply outstanding; it’s just hard to believe how talented some of those folks are.

Check out this model of the engine on the USS Monitor. http://www.youtube.com/watch?v=VWn8gQ9Ykpk

OK so the hydraulic lubricators are finished…now what about the super conductors?
Excellent work Bruce!
:wink:

#412

Bruce I’m running out of adjectives here, so I hope you’ll forgive me for repitition. Excellant details

#413

OK, That Monitor engine is a bit extreme, but cool. Anyway, I don’t think I’ve ever seen a steam turret modeled on an LS loco. Awesome brass work.

EDIT - You should have told me you were going up to Cabin Fever - I might have been able to meet you there.

Errrrr mine all have steam turrents Jon…fer that matter so do most Bmann Shays…

#415

Guess I haven’t been paying attention. Not unusual :frowning:

I was shortchanged. My Shay doesn't have a turret...unless it's hiding in the cab?

A lot of the “Turrets” on steam locos if mounted outside the cab, have the valves inside the cab where they can be adjusted, without climbing outside on the boiler.
The valve for the turbine would be in the cab, and most others too.
The turret just acts like a manifold, where steam lines for appliances can be connected.
BTW the lights would not be turned off and on by turning the steam supply off or on.
Electrical switches were used and quite often if there were enough electrical appliances, there would be an electrical panel in the cab.

Not to be critical; I have to ask; Are your counterweights on the drivers different on the main driver, from the others ? Remember that the main driver has more weight on it with the main rod, and the other rods, than the other drivers with just the side rods.
It requires a larger counterweight than the others, for proper balance.
The few pictures of the drivers, give the impression that you have them all the same. Please tell me I’m wrong…!!!

#418

I guess they could always pour more lead into the hollow castings of the counterweights, if the driver was too out of balance…so I may be wrong. Also the loco you are modelling was not a high speed loco, in any sense of the word, so perfect balance was less important.

#419

Oh yes…I have seen a steam turret that has flexable linkage from the backhead, up to the turret, for adjusting the valves. The turret itself was covered with a metal shroud, which also was insulated to keep the steam in the turret from cooling and letting water form in the lines. CN 6218 was an example.

I'm afraid you'll have to live with disappointment, Fred.
