I am a land surveyor and have done a lot of building layout in my day. I’m curious into pic you show a level on a tripod with a concrete block tied to it. Why? Interesting thread and enjoy the pics.
You step in the feet of the tripod to keep it steady.
I know that!
You know that!
Does HE know that?
I always find myself servicing a vehicle parked half way inside and even the 10x10 doors on my attached garage become a pain. My new shop, still under construction, will have one door 14x16. If that doesn't work, I give up.
