Brummel Hooks - Officially no good and here's the solution

Hairy Dave's picture

Thanks to the good people in our club providing the BHPA with evidence to show the dangers of using Brummel hooks on paragliders, the European Paragliding Safety Committee have instructed the various manufacturers to find a better solution.

At this early stage it looks like there are two possible solutions.

1. For those who want a super quick connection, a quick release swiwel used as a key ring component is being trialed (very similar to the mechanism used already on hang glider pip pins).

2. For those not afraid of tying knots, a lark's foot is a good solution already used widely on power kites.

The quick release swiwel is cheaply available here

I'm told they need a slight modification to smooth the sharp edge where the string goes through (where the split ring is fitted when it's a key ring.) The end of a drill followed by a fine file or some abrasive paper will do that in seconds.

Drawings of knots suitable to tie them on are here.

A clinch knot (otherwise known as a fisherman's blood knot) is ideal.

The drawings also show a lark's head / foot knot, as per option 2. Note that on "cool" applications like paragliders and surf kites, the simple lark's foot can be improved (pimped up) by the additon of a kevlar reinforcement sleeve and a little webbing tab on the loop to help with it's release.

If you decide to try one of these before general release (which does mean modifying your glider, but it's got to be better than a brummel hook) then please let me know how it goes and I can feed useful information back to the safety committee and the PG manufacturers. It would be especially useful to have the regular XC folks who use speed bar in anger trialling the quick release swivels. If you do, I suggest leaving the string extra long with a loop on the end ready for an in-flight lark's foot in case the swivel lets go.

Save the Brummel!

My previous post of a few years ago on this subject described a simple sleeve (see pic attached) which I knocked up out of some elasticated material which has proved to be effective in keeping Brummel hooks both attached - and warm in winter. Easy to slide over, and off. A number of my fly buddies and members of my sewing bee have them too. As I have not claimed intellectual property rights on this innovation why not get some made yourself, they work a treat and will help to keep the Brummel out of the list of endangered species.

Brilliant solution Barry -

Brilliant solution Barry - and the only one I would trust, I too have been using a 37mm length of clear silicon tube which slides over the hooks just like yours.

Brummels are for signals

Brummels are for signals officers and have no place on an aircraft!

You have not innovated, many have done variations on this before, but it still doesn't make it right...

Brummel hooks

Never liked brummel hooks. Seen too many poor quality ones where the opening is too wide and subsequently they have come apart unless taped.

My initial move 5 or 6 years ago was to have a single line from the riser pulleys all the way down to the speed bar. This worked well. Nothing came apart, nothing to get snagged but a real pain if you wanted to change the harness or wing.

Moved over to larks heading the loop where the original brummel hook was over a knot in the line from the speed bar. Easy to adjust/disconnect on initial setup, or later if you change wing/harness combination. Never any sign of it shifting or coming loose.

Best of all, it's free.

we attended the meeting

Ned Birkin, Ben, Dan, Stephen Gray, Bruno Nicoletti, Brahim and myself. We all gather at the blue post for the induction in central London and no one from the club turn up, we would like to know "how and when" can we get the induction for us to start using the sites.
Anyone that can help us it would be very much appreciated.

Spent time explaing this on the phone

Hi all,

I explained all this at length on the phone last night.

  1. London Wing is not part of the Southern Club, it's simply a social group of pilots;
  2. London Wing simply tries to help London based pilots and save them the trip to Glynde late on weekday by running induction courses on a voluntary basis;
  3. To find out about inductions at London Wing you will need to join the London Wing Mailing list;
  4. We were unable to run the inductions last night and Matt Pepper has offered to do them on a one to one basis, over the phone, details were placed on the London Wing mailing list yesterday;
  5. If you are not happy with the London Wing way of doing the inductions then you need to go Glynde on a Thursday evening.

Please can Dave Massie or any other admin/mod split this thread so that these two posts appear in coaching, if that's possible so as not to hijack the Brummmel Hooks discussion.

SteveU.
HG/PG.

PS. If any of you e-mail steveu at online dot fr I will forward you Matt's details and offer.
