When something spins around an axis, engineers measure it by its moments. That’s one of the many things I’ve learned studying for my ETCP Theatrical Rigging certification. Because we have a client that wants to see one. I’ve been doing this ore than 20 years, but its still a big, complex, convoluted technical discipline, and I learn a lot every damn day.
- The top channel in a pulley, where the rope goes in, is called the “swallow, and the bottom part, where it plays out is called the breech.
- Manila rope is graded by something called the Becker Value. It measured with photoelectric reflectrometry (so by color) and is obscure enough that you may know more about it right now than most rope dealers.
- Manila rope is also stronger than hemp rope , so it is no real loss than you can’t readily find hemp rope in the US. Theaters would buy manila anyway.
- Calculating the forces on three point bridles is insanely convoluted. Like skip that question and come back if you have time because there are literally 17 steps.
So my approach to studying, after flailing around a bit, is to alternate between three textbooks:
- Stage Rigging Handbook (3rd Edition) by Jay O. Glerum
- Rigging Math Made Simple by Delbert L Hall. The link is to the 3rd edition, but the copy I have is the second edition.
- Entertainment Rigging by Harry Donovan.
I try to read a chapter a day in each book, and do the problems in Rigging Math.
So that’s one ball in the air.
I still try to market my hiking guides and still contribute to the blog my publisher set up for that purpose.
In writing that I learned that it takes about 3 hours to put together an 800 word article with pictures. But I couldn’t hike inner basin without telling someone about it, could I?
Another ball far from my hand but not forgotten is Go Action Fun Time
It turns out that marketing a new Role-playing system has an extreme degree of difficulty. The trouble is the learning curve vs the plethora of established systems that people are already familiar with.
Scott Thorne, of Mongoose Publishing cites: “Lack of interest by customers in venturing outside their comfort zone. There are very few “Igors” (cue Dork Towerreference) who are willing to try a brand new RPG just because it pops up on the new release shelf. Most stick with the tried and true, going for the new Pathfinder, Dark Heresy, or, much less than in days of yore.”
My quest for game masters to play test this thing remains at zero hits.
And I just sent the complete manuscript to Beanstalk and Beyond to my publisher. That’s right, they signed a contract for a book they had yet to actually read. Good thing they signed it with me, huh?
