Tow rope thimbles by
Bob Hills
What is the consensus of opinion of using steel thimbles on aero tow ropes?
Currently we use some clear tubing in the loop to protect the rope from wear of the Tost tow ring. Not only does this allow the rope to bend sharply causing a weak point but it also seems to fill with dirt. This then...

Grob 109 wing pins by
Bob Jenneson
Hi,
I am seeking advise on the replacement of the wing pins fitted in the
end of the spars on Grob 109 and 109B.
This also applies to the Grob Twin Astir.
A brief history.
These pins are welded to a plate that is glassed into the wing spar end
during manufacture. It was found out at a later...

Garmin 196 or 296? by
Bob Jenneson
I have just sold my Garmin Pilot 3 and want to upgrade to another
Garmin, possible a 196 or a 296.
I have a mate with a 196 and it does a great job. Has anybody had any first
hand experience with the new colour 296?
What is the colour screen like to read especially in a sunny cockpit?
Is it worth...

Older Pilots and Safety by
Bob Johnson
There's a good discussion of this subject in the current issue of
"Flying" magazine written by the editor-in-chief, Richard L. Collins.
This monthly is of course chiefly aimed at General Aviation (read power)
pilots but there are several points Collins makes that could profitably
be extracted for...

Fritz Kahl Passes by
Bob Johnson
His funeral was held today in the adopted town he so dearly loved, in the
First Presbyterian Church of Marfa. All who knew him will know what an empty
space his leaving has left in his family, in the Davis Mountain area, and in
the aviation and soaring community of West Texas.
Enlisting in the...

Winching: Steel vs. Plasma by
Bob Johnson
Further to Craig Freeman's post of July 28, photos of our new winch are
available at our club web site at http://www.permiansoaring.us/
The winch was conceived and built by Craig in about three months of
spare time work, which is surely remarkable. Even more remarkable, Craig
also wears additional...

Winch dangers in general by
Bob Johnson
It wouldn't hurt to repeat this message also -- any location thinking of
going to a winch operation would do well to absorb the lessons in Derek
Piggott's "Ground Launches" book. This 83-page book distills over forty
years of European and British winch experience. The author has had over
10,000...

Winch Physics by
Bob Johnson
This has been covered in these pages before, but it may be timely to
post it again in view of the coming fuel price squeeze and the increased
interest in winching.
This Excel spreadsheet explains mathematically why a winch system

Winch line drag by
Bob Johnson
Does any aerodynamisist (!) out there have an opinion concerning how
much higher than unity the drag coefficient of a rope or wire cable is
likely to go?

Spectra winch rope by
Bob Johnson
Don't overlook the advantages afforded by the incredible lightness of
this new type of rope. Mass and ground friction of comparable towline
diameters are reduced a whopping 80 percent. Ground run distances for
heavy two-placers are thus reduced 25 percent and the ship gets into the
air in 2.5...

Thermal locators! by
Bob Johnson
Serusly, maybe Dr. Jack can log in with his forecast of when he thinks
real-time moving map cockpit displays of current thermals, or (let's not
be unreasonable here) 1-hr old thermals will be available.
Or does he think there is a physical limit to this problem, beyond which
we cannot go? (Like 7...
