Without an engine sitting in front of me this might be a stupid question.
Is there a place to thread a bolt on the front of the engine, fairly close to the center of the stand’s rotation?
And if so, could a guy.....
* place a strong bolt through strong chain, (large enough links to let bolt rotate freely, washer on the other side)
* fix other end of chain to very sturdy item overheard.
This wouldn’t be an assist to rotating the engine, but a safety measure against a catastrophic tip over event.
