Quote from: tcsharpen on May 24, 2024, 03:29:56 AMMy KS-123 arrived today. I first set up to sharpen a kitchen knife using the KJ-45 jig with the KS-123. After getting it all adjusted, I then measured the projection and entered the values into Calcapp which said the USB height should be 88.6mm. Measuring this after the angle setter was used yielded 88.7mm. I'd say this is well within specs of my inexpensive digital caliper used to take the measurement.
Even the first setup was quick after having watched the Tormek video.
Great to hear. I have 2 support bars so for knives I will be setting one for honing and one for sharpening. I will use my jig for setting the projection distance on each knife. Going this the new KS-123 won't be used too much unless someone wants a different angle.
I then used the angle setter to set the honing angle to 1 degree greater. Simple, with great results.
Quote from: tgbto on Today at 03:31:00 PMQuote from: Ken S on Today at 03:10:24 PMI am confused by "concave edges". If you mean cambering edges on plane irons (grinding back the outer edges to eliminate "plane tracks"), the SE77 is the ideal choice, as the amount of camber can be carefully controlled. Before we had the SE-77, we used the SE76 and leaned on the corners. This produced cambered edges which, if not exact, were usually close enough.Thanks Tgbto!
Yes I should have used the term hollow grind, or is it "ground" (?), also a confusing term. Is it the same thing?
The OP really is talking about a concave edge as in ground with a wheel instead of a plate (slightly convex edge) or a belt (more pronounced convexity depending on pressure and belt slack) :Quote from: Swemek on Today at 11:13:32 AMWhat i don't know is how well or bad planar blades is with a concave bevel? I'm currently using my works sharp belt sander for dito, which gives me a convex edge and that works great.
In theory, convex blades have a tendency to skim/pull out, concave blades will dig in. I don't think you'll notice much of a difference in practice because the convexity will not be that pronounced over the thickness of the blade.

i thought the laser would help when lifter to keep all of the blade edge cutting from the same spot on the stone, to keep the same angle.
Am i misunderstanding this part?
