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

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

[phillyjudge]

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….

If you are doing a 70:30 edge as shown in the drawing then both units are capable of that. 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. That said, if you are trying to do different angles on either side of the knife then the WE130 is the only way to go.

 

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 the 50/50 and the same degrees per side on the 70 bevel  (steep) side as the 30 bevel  (shallow) side? I quickly used my phone as a protractor and got 20* on the 70 bevel and 17 ish on the 30 bevel?   If indeed the 70/30 bevels have the identical individual angles, then my sharpening technique is not as horrible as I thought, because I can have identical angles when I sharpen (and I check FREQUENTLY) and lopsided bevels!

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 WHERE does it go? I just put it above the spring

How does one remove the lower wedge thingy to clean it?

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

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.

[phillyjudge]

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.

[phillyjudge]

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

[phillyjudge]

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?

[phillyjudge]

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