It's taken 14 years to disassemble and re-build the numerous parts on the Diamond and Caldor No. 4. Lead machinist Sam Thomson took almost two years to design, build and operate his "Rube Goldberg" valve resurfacing tool. He finished shaping the valve surfaces on the locomotive's three vertical engines last month.Then two weeks ago, the crew reinstalled the crankshaft while I was on vacation. Sam's next project will be to complete the middle eccentric.
As Keith Berry says, the Shay is going together "one piece at a time." We're all happy to see her going together.
