[SML] Fly system SWP, SOPs, P&P?

Thanks Bill

Before I start cutting different lengths of rope off the spool to see how much I need to make the loop, any thoughts of how much rope should I start with?

10’ loops to < 5’ which seems short in my mind.
20’ loops to < 10’ which after the joining knot at the tails, pluss the prussic, still seems long.

13 – 15’??

Oh, I had a look today, and the operating line is a black twisted rope (not a smooth “modern” climbing style of rope).  Does that make a difference when using a snub knot?

I know there is the manufacturer’s binder in the venue which will have a bunch of info I need to read.  I just haven’t got there yet, and am looking further out to make plans to make our professional upgrades to the space.

Yes, zat helps.

thanks

While the concerns over a failure in the floor block guide tracks or guide shoes, and even more compelling reason to use a snub knot is focus.  Having a lineset out of balance is a dangerous condition and the flyperson needs to have a clear focus on what’s going on with the lineset.  By its very nature, the Uncle Benny (aka line lok, uncle buddy and a host of other names) is difficult to install and even more to remove.  The technicians focus tends to be on trying to keep the uncle benny from swinging up and hitting them in the face.  Meanwhile, the lineset is a few hundred pounds out of balance and its operating line wants to move.  Fast.  If you’re messing with the uncle benny you may lose the grip on the operating line and then all hell breaks loose.

Snubknots are easy.  They can be installed and removed blindfolded (I’m not suggesting you do this, however) and allows the technician to maintain focus where it belongs.  On the operating rope.

And yeah, there’s the floor block pulling out of the guide tracks and hitting you in the shin.  Or worse.

Zat help?

Unkle Bill’s 21st Century Rigging book has a lot of that. And snub knot preferred.

Hi everyone

Recently my worksite has been given managerial control over a 100 year old (renovated 10 years ago) small proscenium house.  It’s got 38 fly lines on 8” centres.  Single purchase.

Part of my to do list is to create the paperwork around the safe operation and training of staff and university students.

Rather than start from scratch (I last ran flies 20 years ago before this job), I’m hoping to get some documents I can crib from.  The University has its own template files, I’m looking for sources of the language, risk matrix, things to include etc.

If you have any documents for a fly system titled the following, would you be willing to share?

Safe Work Procedures
Standard Operating Procedures
Policy and Procedures
Operator Rules
Training documents

Thanks very much.

PS:  what’s preferred for out of balance lineset while loading for tall set pieces or soft goods:  snub line, twists, or Uncle Benny?  I think I know the Hive’s answer, but just to confirm….
