I really like the idea of finishing the root cellar.
One of the main issues we were having at the PTJ (besides too few willing workers) was the time it was taking to make the saddles.
I found this
Turboplane 4" Tungsten Carbide Woodcarving Disk which attaches to an angle grinder
At multiple points during the video you can see it being used to carve a concave section fairly quickly.
I think this would really help speed up the processing.
It is not cheap ($179/disk at time of writing)
The other major problem we encountered was Rex, the excavator.
By the last day he was exceptionally tired... Multiple leaks in the hydraulic lines and issues with the cab being unstable/unable to lock rotation/forcing the operator to manually maintain the orientation (though, I can't remember if JR said that was/not related to the hydraulic issues...)
I believe there's a chance we could finish without Rex, but I think it's a longshot.
We have most of the logs on top, could possibly get the remaining few up there with a gin pole, but in order to button it up, we'd be doing a lot of manual dirt moving.
Can't drive the tractor on top... or at least, I won't be driving the tractor on top.
Regardless, though I'm not quite a ringer, I'd be down to come for a week and make progress here!
A workboree to make up for lack of jamboree?
Less structure/fluff more targeted working?
Honestly, I'd be down to stay at the lab the whole week and work.
Skip breakfast and lunch, eat dinner after dark. Get the most out of those ultra long Montana days.
The stone ain't gunna grind itself ;)
