I have thought a capstan winch would be handy, simple, and not as expensive as a 3pt logging winch..
The reason being I have several 30 meter (about 150 foot) roofers master safety ropes..
They are incredibly strong and when they expire, up here they are garage sale cheap..
My main concern with a homemade, pto capstan is getting an appropriate ratio gear box...
What is available ?? What is a good ratio to use for say a 4 or 6" diameter capstan..??
Forgot to ask... What is an appropriate rpm for a 4 or 6" capstan ?? ??
