How about a curved threaded rod milled similarly to that used in the rotomatic between the legs of a protractor calculated so that flat spots on one side represent 5 degrees and on the other 10 degrees or something like that?
With flat bar stock wide enough to place the arc rod deep enough so that it isn't in the way it might work. ----- Original Message ----- From: Tom Fowle To: [email protected] Sent: Thursday, June 19, 2008 12:36 PM Subject: Re: [BlindHandyMan] RE: measuring angles: Dan, I was imagining some means of repeatably mounting the rotorule on the legs, have to be thought about. Seems to me you'd use the sine formula for angles up to 45 degrees and cosine for 45 to 90 degrees. since the sine flattens out over 45 degrees and therefore gives much less resolution. but it may not matter. We'll mess with it when every one gets back from a spate of conferences and vacations <GRIN> Tom ------------------------------------------------------------------------------ No virus found in this incoming message.
