I used to use 3 big long water pipes, bolted loosely at the top, to form a tripod. DON'T USE SUCH ON A CEMENT FLOOR, only in the DIRT!!!!!
Once, while it wuz RAINING, put a tarp over it & assembled an engine, in our TEEPEE!! I'm 1/8 Pawnee Indian, you know. BUT, never got to stay at the WIGWAM MOTEL, on OLD Route 66.
MANY years ago, I saw Chief & Uncle Pappy, pull a Model A motor, using a chain & a long pole!!!! They set it on the front crossmember & I balanced it, while they RESTED!
