If I’m remembering correctly, Celluclay has a powdered glue binder... it’s basically a paper mache product. I’ve always used it mixed with a 50/50 solution of latex paint & water until it’s the consistency of thick oatmeal. It needs to be applied in a fairly thin layer - about 1/8” or it will tend to crack since it shrinks as it drys.

Sculptamold uses some kind of molding plaster for a binder and doesn’t seem to shrink or crack as much when it drys.

Man I hope you're wrong. I just spread a bunch of it. The fibers seem finer than Sculptamold and I liked that. And I pile it on. Some spots are 1" deep. It's drying now.

yes, have used celluclay back in my HO days (1970's-1990's)
cracking as it dried and shrunk
i remember reducing the amount of shrinkage by using a fan
blowing air over the scene.
also, IIRC, those cracks were fairly easily patched with more celluclay
or patching plaster (the kind in squeeze tube that is pink and dries
white.
hope it works out for you!

Sincerely
Gary

Quick update. No cracks yet, I upped the fan to a 20" box type. I even painted over parts of it. So far so good.

Here is the town side.

Still need to "make" the coal mine, but as it turns out I found a bit more than one photo about it.


This must of been later on. Early it was called the O.P. mine.



Compare the last photo with today:

I'm up to my 10th Shapeways upload... keep finding things to change before I order it in brass. Here it is in home made resin.

Are you worried that the brass boiler is going to put a lot of weight on one end, or are you going to add weight under that tank on the butt end?

Scott please remember to scale your model up for at least a 2.5% shrinkage rate in the brass.

The tank is hollow, but I really don't think the weight will be that great to be a problem. In my test video I was using nothing but a resin frame for weight and could pull 3 cars up a 4% grade.

Even though you can see your 3D designs on a screen. When you print them out and hold it you can see things to change. The gap between the cab and the water tank was much better than a big square split frame would have been and everything will be painted black to hide it. Still I figured I could trim my flywheel coupler a bit and then all you would see is a 1.5mm shaft.

@Lemosteam  the brass pilots I had made for another Climax didn't shrink much at all. At most the part is about .0015" smaller than I drew it.

More pics. The other side:



Back in town





At the mine I will put a trestle over the main to a tailings dump. This will let me model the little electric mine tram.

Today right before installing the fascia on this side I decided instead of one big drop on the waterfall to make it a two stepper.


Then over to the right I scratch built this little depot to look like it was an old boxcar.


It also hides the slide switch for the turnout  :)

And it seems the prototype tipple I chose to model has all these photos due to a "mine disaster" in 1910. There was an explosion and 15 people died. This was just 2 days after the mine was inspected. The explosion broke the windows of a passing train.

The rail line was the Lake Erie, Alliance & Wheeling Railroad and originally narrow gauge. Later it became the NYC and Penn Central. If you follow the line North it ends ate the Erie RR line to Cleveland. There were a $hit ton of coal mines along this line going South. On Facebook people talk about walking up into the tipples to get paperwork before leaving with the train.

I scaled the Climax model up 1.5% and placed the order  :scared:

The body was $151, but they have a processing fee, shipping, and tax. The total was $180  :scared: And it will be a while, their estimated ship date is Oct 7th so I won't know for a while if it is trash or not. You can pay and extra "hurry up" fee, but I didn't do that.

Crossing fingers  :scared:

Trackplan


All 4 fascias are mounted and blended in. Track is painted. Touching up a few tiny spots then I can start coloring the rocks.
