The Yarns from the spools on the creels are run through the forming plates. The Forming Machine is on the left. This operation turns yarns into strands.
Strands enter the thimble on the Forming Truck from the right and emerge through the laying twist as rope on the left.
Seen just to the right of the creels in the near alley is the Foreturn Machine. Yarns run from it to the Forming Truck (center machine).
The Laying Truck with its laying twist are on the left. The Forming Machine, which is part of the strand making process is on the right.
My belt driven winder is on the left. The afterturn machine on the right is in the same alley as the Laying Truck and the Foreturn Machine.
The Foreturn and Afterturn Machines twist the strands in opposite directions. The Forming Truck, located between the two, forces the strands into a single rope.
From left to right are the Winder, the Afterturn Machine, The Forming Machine, and the Laying Truck. Look closely. You should be able to see the drive ropes around the wheels on the two machines to the left. These provide the power to turn the gears in both machines.
These (on the left) are mortised and tenoned into the outer wall. They are removable to allow for the passage of machinery up and the far alley. The arrow on the left points to one of the mortices.
In the lower left is a brass mortise jig I made for drilling out the mortises. I used a scalpel to clean the excess wood out of the holes. On the right a scale 4X6 inserted into a finished mortise. Note: the framing members of my walls are half-lapped.
These are 3D printed objects and I initially made them to swivel. After installation there were fixed into either their opened or closed positions.
You can see the drive ropes here in both alleys. The original building was 1,050 feet long. My model is only 140 feet long so some selective compression has occurred.
This is process photo showing the unfinished tank gauge. The water tank roof is a single piece 3D print.
I'm still working on the painting technique for the roofing. This method used table salt as a frisket between layers of paint.
