Well a lot has happened since the beginning of October. There will always be small projects but the shop is officially "done".
First, the shop sink was officially hooked up to the waterline we ran from the house this summer.
We also installed the furnace with A/C coils for next summer. It is a Concord 88/90,000 btu unit with a 94/96% efficiency. Initially, we intended to use a Reznor garage heater but for the same price as a 80% efficient unit we got ~94% efficiency plus the option of air conditioning. While waiting for the propane install the shop stayed at 54-56 degrees with 20-45 degree outside temperatures and just a plug in oil filled heater like you would put beside your couch. Last night we finally got the propane hooked up using (2) 120 gal tanks. It fired up and worked nicely with the ceiling fans running on low.
Note, since the furnace with A/C coils was just barely too tall to fit on top of the office (this wasn't the planned location) we had to build a cantilever shelf to hold it above the workbench. This messes with my light distribution on the bench but isn't terrible.
Between installing the furnace and getting propane, we dug more trenches. The first was a French drain on the top side of the shop running to the pond. The sink Y'ed into this after I transitioned to schedule 40 PVC from corrugated drain pipe to go under the driveway. Next we ran the rest of the 2" conduit to the old barn built in 1911 for underground power. I also threw a 3/4" conduit in case for some reason I want ethernet in there (baby cams for livestock?). Last week I pulled #2 aluminum XHHW through the conduit. I had planned on #4 but the supply house didn't have 450' of it and for $20 more I got the #2... I had 360 degrees of bends so it wasn't an easy pull... This whole underground operation eliminated the low hanging overhead line from the house that has been knocked out before by delivery trucks... It also put all ag buildings on the same meter vs the house.
