Now that the dunk bucket is truly a block of ice, I have been playing more indoors. I got to fiddlin' with some php on my web server and come up with this calculator. http://dcknives.com/public/grind_angle.php It's based on the stock thickness and desired grind height. The result is the angle in degrees, using the formula: atan(thickness/height)*(180/pi) for single bevel blades or atan((thickness/2)/height)*(180/pi) for double bevel blades Let me know if you find it useful. Or maybe my math is rusty. Cheers, Dan
it matches up nicely with my spreadsheet when edge thickness is zero I use the edge thickness version occasionally =DEGREES(ATAN((0.5*(StockThickness-EdgeThickness))/BevelHeight)) with no edge thickness =DEGREES(ATAN(((0.5*StockThickness)/BevelHeight)))
Yes, there will always be some small issue with the precision depending on how thin you want to go before setting cutting edge and some rounding on the output. But for a guide I think it will work. Sorry to all those metric folks. Dan
