Today was dedicated to work on the shed, leaving no time for work on the 1130 system.
I finalized the positioning of the 12 concrete pilings upon which the base of the shed will sit. Since the shed just fits into the space on the side yard, between the wooden fence at the property line and the living room fireplace chimney, the pilings have to fit against the fence. Each upright on the fence is set into cement in the ground, thus the piling can't be sunk into the ground at those spots. I worked out a siting and spacing that clears the sections of in-dirt cement and fits along the chimney brickwork.
The pilings have to be flat and in line, so that the wood framework will sit in the notches of the pilings and be level in all directions. The terrain was not flat, requiring some excavation under each piling. The pilings are roughly at the same height, based on using a large beam and bubble level, but some fine tuning is still needed.
I also cut all the wood for the framework to size, then began nailing in the cross pieces. I have all the cross pieces completed for the side that will fit against the fence, since there will be no space to swing a hammer once the framework is in place. Three crosspieces on the other side must be put in before the framework can be placed on the pilings, since these holes are partially or fully blocked by the chimney brickwork. The remaining cross pieces can be installed while the frame is in place.
Tomorrow I have to finish the leveling of the pilings, install three cross pieces, then haul the heavy framework over to its final site and place it onto the pilings. It shouldn't be too long from that point until the flooring is in place and I can start erecting walls.
I completed the right door assembly as well, so that all the sub-assemblies are complete and ready to put into place. Another task I did in between carpentry and digging was to plan out the placement of the 1130, its peripherals, the keypunch and storage for cards and disks. Since the inside space will be approximately 89" by 146", it will be tight inside. I have a workable layout.
