I remember my father telling me that right after the way he and some of his buddies got into building hot rods and dirt track race cars and since nobody out in the country had a garage, they used a stout tree limb to pull engines in and out of all of their race cars. The only time they did a job for money was for the only neighbor that had a nice Lincoln and of course the limb broke and the engine fell right on the fender! It was a funny story years after but I'm sure it was not funny at the time. They then decided to build an "actual" hoist frame out of huge timbers someone found. I got the biggest kick out of the description of actual hoist built of timbers like it was a precision steel frame crafted by the finest machine shop.
