According to foundation Keith Berry, Weiss used "his long standing experience as a machinist to make or repair parts where we have no drawings."
During the past year, Weiss dedicated about 50 hours per month to the renovation of four key El Dorado County railroad artifacts. Projects included:
- Fabricated replacement brake shoes for the Camino, Placerville and Lake Tahoe Track Inspection Car No. 4
- Rehabilitated brake linkage for the rear truck to the Diamond and Caldor Railbus No. 10
- Machined pins for the valves and brake linkage on the Diamond and Calfor Shay No. 4
- Fabricated a new handbrake staff and chain roller for the Diamond and Caldor Flatcar No. 10
