The main element of this project is 2 HP Chain Saw and a very solid worm gear.
Chain drive may seem like a strange solution, but believe me, the bicycle chain is very durable and resistant to heavy loads.
It is possible to use a V-belt and pulley. It may be a better solution.
Unfortunately, the clutch in my saw did not allow it, so I did a chain transmission.
Sprockets were previously used, but their usage was low so I could use them again.
The drum was made very solid, but it should be more rounded, which would give less rope resistance.
I decided on such a construction and use of a rope instead of a steel rope for several reasons: - I can use an unlimited length of rope (steel rope always has a limit) - Safety
Breaking the rope does not pose a threat to the person who is operating the winch.
Pulling force does not decrease because the rope does not wind on the drum
To stop the winch you have to let the rope. (It is a very safe method for the user)
The speed of unrolling the rope is incomparably faster to standard winches.
