Just food for thought guys, not advocating one way or the other.

Here is a screenshot from Cedric and Ada on YouTube

Thank you for the reply, it’s the scrubbing that I think is causing me the difficulty.

this is what boggled my mind:

The angles are identical on either side but the blade is intentionally sharpened so that the ratio of bevel sizes is 7:3. You simply need to spend more time working the side with the larger bevel.

Thank you…my “issue” is I did not intend to have uneven bevels….My mind was aching with the statement that bevels can be uneven and still meet at the same angle…is that possible ( i.e 20/20 angle with a 70/30 bevel)?? If so, my technique is resulting in a geometrically correct /even angles but visually different bevels….

MY MIND IS ABOUT TO EXPLODE (and maybe in a good way)….I admit, geometry was not a strong suit….How on earth could 2 lines intersect at a point and have the same angle in relation to the center line and one have a steeper bevel than the other side?  Are you saying  that in the diagram above, the 70/30 bevel has the identical angle to t…[Read more]

YIKES!!!

just saw Marc H’s link for cleaning.

I love this place.

My vise is making really bad groaning noises and seemingly not clamping fully anything greater than 1/8th without feeling like I’m forcing it. I removed the jaws, blew it all out and reassembled but it’s only marginally better.

The foam thing was rescued but WHE…[Read more]

1. Reply to airscapes, I have the newest vise, ball joint arms and just got the new micro adjusts.

Who says I’m human?

muhwahhaaaaaaaahaha

Thanks, fellas. I cancelled my therapy appointment.

MarcH, I am going to do that, I can’t understand why the left side would be off compared to the right.

TC, thanks, but I am so concerned about precision, (or is it accuracy), that I am trying to reduce as much error as I can, and I lost my way. Maybe.

But if the angle bar is off, and the rod assembly slides on it, then one side is plus .25 to the other side’s zero….like the bar is bent on one side vs. the other, so don’t I need to account for that?

I men , the zero side will be at 20* and the “wrong” side will be at 20.25*, if i ignore the error.

HAH!: using that analogy; my scalp has a perfect mirror finish! TC; I get it! Thank you,

TC: if I am understanding your opinion, are you saying that the DLF refines the apex by removal of defects only if apex defects were removed at each step? Isn’t that what naturally happens when we progress through the grits?

Airscapes, understood. It gives a more transitioned “wedge”.

MarcH. I hate to be so obtuse, but what is the practical effect of the DLF versus stropping?

Thank you all for your replies, this is wonderful.
