Yes this very slick, I thought the one they had at Lasham was neat.
Although I doubt they need A/C. I am learning in CA and I typically
spend $100/day getting 3 tows admittedly in the beloved or hated 2-32!
More operations should have winches.

Maybe your example (and details) can make this happen!!

Here is an electric one! Bill.

I looked this one over carefully. It seems like a good idea using the
battery pack as a buffer to store up energy from the power source between
launches. It means that the primary source of electricity can be much
smaller than if the winch motor had to be directly powered from the mains
(Or a diesel generator set.) Modern digital power controls are very precise
but, it's a costly approach.

Then I thought about servicing the 570 Volt battery pack - yikes! One wrong
move and you get fried. I've heard harrowing stories told by old
submariners about servicing diesel boat battery packs - no thanks, not me.

Direct diesel power delivered through a Voith fluid coupling still seems the
best way to go. At least when you shut down a diesel. it's inert and safe.

You know, just south of Totternhoe!

I have only just found the posting with the link to pictures of the
Permian Soaring winch [
http://www.permiansoaring.us/ ] and was a bit concerned that there is
apparently no guillotine, to be able to sever the cable in the event of
a hang-up at the glider end. Is there one and it is just not visible?
If not, what is the emergency procedure to ditich the cable?

There has been one fatality that I know of in the UK (maybe more) when
the release hook on the glider failed to operate and the glider flew in
an arc pivoting round the winch until it hit the ground. There have
been escapes where the cable wrapped round the axle or caught in some
other part of the glider (e.g. diving under the cable and getting it
over a wing, when there was a power failure or whatever) and the
guillotine saved it from being a disaster.

Did the operators pick up from experienced winch users how best to set
up the cable - hosepipe, weak links, swivels etc.?

Are swivels necessary and/or beneficial with the synthetic cable?

Is the winch earthed before use?

Not trying to teach grandmother to suck eggs, but anyone starting up use
of a winch needs to find a lot of know-how from others - or learn it the
hard way. My club started using winches again after a long gap, would
not pick up expertise from others, and had some hard lessons,
fortunately without major accidents but certainly with some near misses.
Like the guy who had a huge electric shock getting down from the cab one
day and then realised why there was an earthing (grounding) spike
provided.

I am looking for a dependable way to cut Plasma rope. A guillotine
will be installed as soon as this question is answered. Any ideas
would be appreciated.

We used what information was available to us. Derek Piggot's book
on winch launching is a must read. Proper setups are very important.
Sadly, they are not widely understood or perhaps respected in the
USA. I had one very well respected sailplane supplier ask me.
" Why do you want to use color coded tost links, let me sell you
some certified rope" Been there done that rope no worky. At least
not as dependable as necessary. He did sell me what I wanted and
guess what no more weak link breaks.
The USA is just having a little trouble getting up to speed on
winch launching. Thankfully we do not have to invent this wheel
just learn from those who have gone before us.

No swivels needed with hollow braided ropes.

Is the winch earthed before use?

Static? That's new to me. Thanks-

Good advice my winch launching friend.

You may want to have a look at
http://www.aec-landau.de/projekte/PE-Seil/vortrag.htm

They have modified their winch to cut their PE cable. You find the email
address of the author at the end of that page.

Eggert --

You've been such a graet help to us I hate to ask one more favor, but
could you translate these pages for us poor old igorant cowboys?

Computer translations are hilarious.

I very quickly looked for the cutting method:

Seems to me they converted their Guilutine to have a Brass Anvil on
which a cutting device will cut the Cord/rope, Like an axe or
similar. Guess more direct rather than shearing?
