Make the pulley out of flat plate with bearings around the outer edge so the
pully has no momentum and thus does not keep spinning and wearing away the
rope. ...Ian M

Subject: [Aus-soaring] Reverse pulley launching
Does anyone out there have any info or experience with reverse pulley
launching? Our plan is to use a car on a limited length airfield to launch
an unballasted 15m glider. I do remember an article in an old AG some
years back, but can't find it immediately. Any help with pulley
construction, rope guides, rope type, power requirements etc would be
appreciated.
