For those confronted with a 120K Purdey and fond of quantification but scratching their heads about where in the world to acquire a "five-foot protractor", if you can find a couple of hdware store yardsticks or two pieces of lathe, a bolt and wingnut and the means to drill a bolt size hole in the end of your two sticks, you can pretty quickly have a large adjustable bevel or angle taker. The plastic protractor your kid uses at school will do the rest. Aside from this mere quibble about the availability and sophistication of measuring devices, I agree with JL.
