MODELING INSPIRATION - Pt. II

At the same tractor show, they had set up a sawmill,
and demonstrated sawing with steam power.






A steam tractor was hooked up to the circular saw drive,
by a long (about 30') belt.

The belt is hooked up when slack,
and the tractor backs up slightly to put some tension on the belt.

The belt takes an amazing amount of letter,
it must be 8" wide at least.  

The belt is powered by a drive wheel on the steam engine,
mounted on top of the boiler, connection to the driving wheels is cut.


It was nice to hear the steam engine chuffing away powering the saw.

The sawyer and tractor engineer worked closely,
via whistle signals for start up and halts.

Although this was a tractor powering the sawmill,
I could easily imagine a stationary steam engine in its place,
and a narrow gauge rail spur serving the mill.






The circular blade easily cut through the cedar logs,
with the powerful steam tractor hooked up.

I watched the sawing of logs for quite a while,
it was great to see, hear and smell the sawing action.

The mechanisms and machinery were easy to observe,
since none of it was covered with shields or other safety devices.

The workers definitely had to pay careful attention to avoid accidents.


A small mill like this would be a great model to to add to my railroad.






Before I left, I stopped to admire this concrete mixer.

It is powered by a single cylinder "hit and miss" engine,
the cylinder drives a large flywheel, and fires off only intermittently. 

I have a plastic Preiser model of a concrete mixer,
but it is built to be powered by a more modern gas engine,
I think I will backdate it to create something resembling this machine.



So, there is modeling inspiration all around,
it doesn't always have to be a railroad or railroad museum !
