Hey, Q.
The Wicked Edge team is in the process of squaring it away. One more week and I should be set.
There is one more thing I need to figure out after getting my stones back, but that’ll be a few weeks out to test and verify. If my guess is accurate, I’ll create a step a step and post it for peer review here.
Sincerely,
Drew

Alright, I’m back.
I want to thank everyone who offered advice in this issue. It was a monumental cause-check session that took an unexpected amount of man hours for you all to walk me through this.
I’m betting that this’ll be handled by WE directly.
Don’t think for a moment that I don’t recognize and appreciate you all for offering…[Read more]

Oh man, our replies were overstepping each other. I missed a few. The 200 grit left the marker, and I haven’t checked for dishing, yet. There’s a good straight-edge on the property, I’ll have to track it down.
It feels like my eyes will start weeping blood like a WE stigmata if I pursue this further, today.
God bless you all, and I’ll get to…[Read more]

I’m done, Marc. It’s many of the stones, 50-1k. Thank you for your effort. Good stuff.
I’m going to request another set of stones, or return the whole thing for a refund.

Man… Listen. Either I’m not getting a fairly simple concept, or you aren’t. I’m about to lose the last of my mind.
All I want is for the finer grit stones to contact the bevel the same at the created, ground degree as the courser.
All things being fixed and constant, including the tilt of the blade, bevel stone contact should be constant…[Read more]

200 grit, 15°, marker to illustrate

Here’s the last experiment I’m doing today to highlight the problem:
100 grit, ground fresh bevel flat, apex to back of bevel, bur raised on both sides. Clockwork, and all is well. My reasoning suggests, strongly, that if the 100 grit can reach all parts of the bevel flat, regardless of how the knife is, then twisting the paddles from 100 to…[Read more]

I’m just not convinced. Regardless of how the knife is positioned in the vice, if it’s locked in tight and ground fresh, with no movement in it, that angle of bevel should contact the stones the same, whatever grit I use.
Everything is consistent, that I can tell, besides the stones.
Are you saying that this system will only work putting…[Read more]

… it won’t let me post the last orange bottom reading picture. It reads zero, on the money.
Marc, looking dead on the point of the knife, the spine is clamped slightly left of center. It’s sitting more on top of the left vise-pin.

Found a small 90°.
Base bottom, degree bar, and vise bottom as contact points. Zeroed cube on base and vertical flat of square. Set paddle to measure vertical. Right paddle first, then left. Bottom first, then top. 800 and 1k sides against square. Holding paddles against the square-flat with pressure on bottom.
It’s a poorly controlled…[Read more]

Marc, I just cubed the flat of the blade. It shows ~.55° off center.
Tell me your thoughts on this.

We’ve got everything packed in totes in storage. I’m going up to check the manifest.

I knew you’d jump on that. Yes, as soon as I track down the square, I’ll test for straight or list.

Tc, I just checked, and the 800-1k stones on both paddles are seated. It looks like the assembler put the stones in the pocket, then pushed each stone to one end of the pocket or the other, stone-end flush with pocket-edge, but the stones are definitely in there.
How would I check the angle of each stone? Put the paddles in the 90 of a…[Read more]

I literally can’t understand what I’m reading, anymore. I got sucked into this in the morning, and haven’t eaten a proper meal yet.
I’ll reread after rest. I dig part of what you said. Yes, 100-200, slight difference in angle. Scrub full flat, 200-400, slight difference in contact at 15°. Easy to correct for with scrubbing. 15 min to flatten…[Read more]
