Being that I do quite a bit of blade HRC testing I noticed a big issue that I need to solve. First is most customers want the testing on the tang which is fine but a lot of the customers blades I do are kitchen knives or other blades that are quite long. The issue is supporting the tip of the blade so it sits flat on the anvil. I have found that this much weight hanging out can affect the hardness reading by a rather large amount. So I need to design something that clamps to my round anvil and has a little arm that sticks out to suport the blade. You can't have a suport on the bench becaus the anvil moves up and down. Any one built anything like this?
The other thing is I also get requests to test edge hardness becaus of a clay coat or edge quench. Because the blades normally have there edge bevels at this time it's impossible to get an accurate reading as the testing surface is not square to the diamond penatrator. Plus I don't want to risk busting that little diamond point. So my thought was to maybe mod something like this to work for an adjustable blade suport. Parts of it would have to be cut off but I think it might work. Any of you solved this problem yet?
Thanks guys for any tips or advise you have on these issues I'm having.
