Many thanks for that. Yes, my Fuller scales were done by Wayne Harrison and look really authentic which is great.(He also did my Bygrave replca scales)The sines are also from 5.8 degree, and no problem since for LHA, declination,Latitude values,I do not think I have ever needed trig values below about 8 degrees, so not a problem If I need that, I'll go to my tables!
So in a perfect world Peter, what would be wonderful for a perfect "trig Otis King" would be authentic, accurate scales plus likewise for sines (+cosine numbers in red going in the opposite direction on same scale. I have done that with my Fuller 2 and it works fine).If you do not feel like doing this, would you mind if I ask Wayne to have a go? He is busy at the moment and it may be some time in the future, but I dare say he would accept the challenge of adapting your current scales, making them "authentic" and generating the appropriate trig scale.)
