Welcome back.
This is the idea that I have now.
This shows the throat on the hollow grinding jig that I built.
This is the sliding angle.
Fixed forward angle.
Wheel is in this area.
This is the shelf that the hollow grinding blank rides on.
What I am planning to do for flat grinding is that I want to use my flat platen.
I will make a carrier for the knife blank to be fixed to and I can then pass the carrier
with the knife blank through the throat of the hollow grinding jig across the face of
the flat platen.
The carrier will be a small L shape.
The blank will sit on the lower leg of the carrier and then be clamped to the carrier.
I am thinking I will put some locating pins on the carrier to pin into the two holes midway
on the handle.
They are accurately located with CNC on each blank so I feel certain that they will be
useful in getting a consistent result while work quickly.
Then I will flip the blank over to do the grind on the other side.
I was concerned that without the carrier the blank would rock back in the hollow grinding
jig throat after one side had been ground resulting in an uneven flat grind.
By clamping it to a carrier the blank will be solid when it passes across the face of
the platen.
I hope to get this idea tested out in the next couple of weeks to see if it works like
I envision.
I have 73 BK Neck Knives to grind so I have been trying to devise a way to grind them
quickly but accurately.
This is the grind profile I plan for the BK Neck Knives.
It will be .020" at the cutting edge before secondary bevel.
The spine is 3/16".
On my grinder I will set the platen at 87 degrees to get this profile.
Take care and have a great day!
Thanks for watching and remember to scratch the frog's belly.
