…I can at least learn from my mistakes.
Well crap! Here I was, all pleased with my freshly minted kanna. Wrote a post all about it. Showed it off…blah,blah, blah. Everything was right with my world, but then…
As I refined the conditioning and tried to take a nice thin, wispy shaving, I began to get really nasty chatter. What the…hmmm…I must need to sharpen. So I honed my blade and reinstalled it. Same nasty chatter when trying to take a thin shaving. My sole conditioning must be off. Nope, no joy there either. That is when I got a sick feeling in my stomach.
The only other thing that could be causing the chatter is a poorly supported blade. Essentially, when set for a very thin cut, the blade will be pulled down and back then spring back up. Chatter!
Son of a….sure enough, after a quick inspection the blade is not contacting the lower portion of the bed. I should have caught this monumental error long before now, long before. Enthusiasm and tunnel vision seems to have led to my downfall. Heck, I even posted a picture of the problem and still didn’t catch it.
The pencil points to the area where there is no blade contact.
Unfortunately, by the time I remove enough of the upper portion of the blade bed, the blade will be far too loose. Yes, I could shim it, but the thought of another shimmed dai right from the start drives me close to crazy. So I’ll be making yet another dai over the weekend. Wish me luck…
