Hello Damon
This has been covered many times here.
The principles are simple.
[1] if the sprocket is driven and threaded the thread will always be LH.
Hence the small top sprocket will be a conventional RH.
The reel and roller sprockets - being driven - will be LH.
Simply put a piece of soft wood through the reel to jam it.
Usually a punch and hammer blow to the reel sprocket will release it.
In the unlikely event the sprocket does not release proceed to plan B.
Protect reel sprocket with old chain. Place a plumbers' wrench over this,
but lock the reel as above.
Hope this helps
Jack
