Team Vision for Integrated System Build & Test Phase

American Printing History Association


The team was selected to present at the 2016 American Printing History Association at the Huntington Library in Pasadena, California. Seth and Veronica represented the team during the 3 day conference. We learned an incredible amount from the prestigious presentations and gained a lot of project interest from APHA members. The presentation discussed the design evolution of English presses in the 18th century. Below is a link to the powerpoint presentation delivered at the conference.

Test Results Summary

Metal

Blacksmith
Our blacksmith continues to impress the team with each part delivered. At the end of this phase, we now have the carriage rails and keys, top hose band, spit, crescent arm, and hose hooks. The team was actually able to swing a hammer to help forge the crescent arm. Below are photographs of the team working with Matthew in the blacksmith shop.
Metal parts are forged from 1018 mild steel. While not quite historically accurate, this modern low-carbon alloy is an approximation of original materials used during the 18th century. This alloy is, by its nature, subject to rusting if not sealed properly. Matthew has been using a coating of his own making consisting of beeswax, turpentine, and linseed oil. The two photographs at the bottom of the chart display Matthew applying the sealant to his work.

Machine Shop
The machine shop is continuing to work on the 3 spindles.

Wood

Seth And Daniel took a trip to Pennsylvania at the start of the phase to purchase mahogany, which will be used for the hose and platen of the press. Later that week the white oak purchased in May was delivered to S.F. Spector in Harrisburg. Due to some issues in the drying process, only some of the wood was usable, and the team had to find additional beams that would be suitable for producing the cheeks of the press.

S.F. Spector located salvaged barn timbers in Pennsylvania, but these were found to be too moist to be practical substitutes. Ultimately, after discussing the issue with the Cary Collection staff, the team chose to have S.F. Spector glue-laminate timbers for the cheeks. These were produced in a way that would hide the glue joints as best as possible.

Aside from the issue with material for the cheeks, production began on the other wooden parts, such as the feet, head, winter, and forestay.
