The Adjustable roofing protractor by Derek Pater
A new Rafter Layout system that simplifies the Traditional Roof Frame Layout method.
This tool has the scope to set out almost any roof frame needed.
The inventor of the adjustable roofing protractor, Derek Pater has his own website and he can be contacted there.
Derek sent me details of his invention some months ago, and it was considering this particular tool, that got me into building this section for inventions.
The protractor is a tool that a complete amateur could buy in a hardware store and within a very short time they could be setting out a simple roof. It comes with a complete set of instructions and a set of angle tables for just about any roof.
Personally I don't use angle tables as I was lucky enough to to be taught when I was an apprentice, by people who had the time and the inclination to show me the old way of solving roofing problems by basic geometrical drawing. What we are talking about here though, is not how to get the roofing angles, Derek provides a simple way to do that, and I use another way, we are talking about an actual tool that can be used to transfer those angles to the timber or steel as the case may be.
On a first glance at the images above you could be excused for wondering what the heck it is, I know that I did, until I began to see the logic of it.
Derek kindly sent me a sample of the protractor, and while it does everything that is described above, my first impression was that it is not solid enough. I honestly think that it wouldn't stand up to the rough and tumble of a building site, and in and out of a carpenter's tool trailer etc. in the long term.
I have since been told that there will shortly be a metal version which will of course solve this problem.
For the non-professional roofer the current model should be ideal. Used sensibly it will last and do the job excellently.

There is no charge for this and also I want it to be very clear to my readers that I don't get or ask for any money from these guys. I am doing it as a service for my readers, but...if one of the inventors happens to get bought out by a multinational company........ well... I hope they remember who their mates are, eh:-)

Just in case you have read a few of these pages and you think that my comments are a bit biased in favour of the inventions, well.... you are right. Why would I bother putting something here if I don't think it is any good? There are heaps of websites that promote crap for money if that's what you want.
