Thread: Chipping after shaving HRC issues? Custom Razors

This is the Google box calculation


(2 * asin(.181 / (2 * .620)) * 180) / pi = 16.786646


The red is the width of the spine the green is the height of the blade from where it touches on the hone... plug that into Google search and voila Math !!!


or let's just plug in your 6/8 calc figuring the height at .740 rather than .750 for the full 6/8 height...


(2 * asin(.188 / (2 * .740)) * 180) / pi =14.5956583

This is about 1.5° low from the accepted 16° target / average we found on Vintage razors, some razors target 17°

At 6/8 each layer of tape adds about .66° to the measurement so you need 3-4 layers to bring it into spec... HT Temper and Steel can absorb some of the variance but building razors to accepted spec makes life easier


This is why we are known around the internet as "Know it Alls" on SRP


ps: I only checked the 6/8 size you can play with the others and see where they come in at
