Any more thoughts on the tow in clinic?

Sam,
I don't instruct but have no problem with showing people how I tow up with a static towline. I also have been known to offer up explanations
about why I do certain things the way I do so that anyone planning on trying to copy my procedures doesn't blow past an important and easily missed safety concern. Having learned since 1978 many of the things that can go wrong while one is towing I tend to avoid stuff which to an onlooker may lead them to believe that towing is almost boringly easy to do.
Some of the big names in towing have offered up tabloid phrases about aspects of towing that can easily lead people off of the well beaten safety trail.
I've watched the chain of events often lead people to remedies that work like time travel. Taking them back to a situation that had spelled disaster decades ago and here they are learning anew the really hard and already proven way.
Example: The lawn mower broke, the grass grew tall on the runway, the launch dolly wheels were a little under inflated, and there was a weaklink break during the tow operation. Simple solution = increase the strength of the weaklink!
Next more tow tension for the first time caused the tow bridle to stretch excessively and when the weaklink broke the release snapped back and injured the pilot. Who would have ever thought that would happen? (For sure some old tow pilots like you and me!)

Bill, Hawks,

That all sounds good to me. We are lucky to have a tow veteran like yourself, in our ranks. :salute:

Personally, I have never had the opportunity to try static towing ground based. Not enough suitable roads in this area.

The low and slow scooter towing works great for beginner pilots and experienced pilots who have never tried tow launch methods.

The equipment I use is standard and widely accepted. Also the agenda.

It would be great to have any kind of Hawks get-together. At a site where u$hPa was not a factor.

Sam, I watched scooter towing done by Ed Bennett when he lived in Alamogordo, NM. Until that time I had always thought that towing should only be taught to at least H3 rated pilots. It changed my thinking and I now know that it can be used to safely teach H1 to tow.
However, when I hooked up to his scooter/pulley, tow operation I chose not to use his bridle that hooked up to the pilots chest area and towed through the control frames triangle.
I hooked up with my old Skyting Bridle that had the weaklink and release out ahead of all the gliders rigging.
I will say that the chest mount area attachment can be done safely with the right horsepower scooter, wind conditions, and an operators that knows what their doing.
The reason I chose the Skyting Bridle is many fold. It allows me to handle too much HP, too strong of wind conditions, and an operators that don't yet know what their doing.
Also and although a student may not yet have to activate a release during the beginning of their tow lesson, I'm past that point and can release if I get gusted 90º left or right of the towline. Some chest releases can have the released towline wrap and capture the left or right nosewire if the glider is gusted 90º to the towline. This is why I prefer to have the release out at the apex of the Skyting Bridle. (Also one of several reasons why I'm not as fond of aerotowing.)
The keel attachment of the Skyting Bridle gives me more pitch authority and protection from being, "locked out over the top."
Too much line tension due to too much horsepower, wind gradient, or an operator that wants your wife, can have a pilot climbing too fast.
My Sport 2 has enough energy retention to allow me to handle a 350 pound weaklink break without showing me a hammer head stall. It would be too strong to use with the 195 sq' Falcon which would show me a hammer head stall due to less energy retention and the greater pitch positive characteristic at its top end airspeed.
We also have a shortage of tow roads due mostly to the creosote bushes, prickly pear cactus, and a host of other desert towline grabbers. Close to Las Cruces we have roads that handle N-S, NW-SE, but nothing SW which is the prevailing wind direction.
That makes it tough to schedule a towing get together in our area.

I know you hide those in your posts to see if we're really reading everything you write.   ;)      Did I pass?

I really like Sam's idea of a towing get together in Las Cruces. Watching your repeated static tows on video gave me some courage (emphasis on some).

August 7, 2018
All the weather models, on Monday night, were in agreement. Tuesday It would be southeast wind at 8 to 10 mph.
Tuesday morning some of the models were staggering in different directions at different speeds.
I'm not sure what kind of models we're talking about here but they must have been paid with beer or it was their
first time wearing high heels.

Like the suckers that we are Robin and I headed for the Exit 116, SE - NW, Tow Road only to find out none of the more reliable models bothered to showed up.

The light and variable winds were mostly south so we decided our best course of action was to revert to our hang one (H1) way of thinking and start chasing the wind.

Half way to the 3 miles distant north - south tow road we noticed it was blowing out of the southeast.
While still caught up in H1 mode we raced back to the SE - NW Tow Road only to find it light and variable, mostly cross, and sometimes out of the southwest.

As airtime deprivation panic took hold of me going to Mag Rim or even the Little Florida Mts dashed through the aggravated conversation. (It was hopeless.)

With both of us back in hang four (H4) mode we started for Las Cruces.

We decided to check out if the road to Volcanic Peak had dried up and swung over to the south. It was dry but the rain
had really carried away parts of the road so that a car would now have a tough time getting to the launch. Vehicles with some clearance are needed now. The road up to launch took the worst hit. Robin braved the rattle snakes and cleaned out the culverts on the road up. We also moved rocks and made damns in an effort to save the road from the coming rain.
