Putting back bevel using Veritas Jig

Does anyone know how I can use the Veritas honing jig and bevel guide
to put a 5 degree back bevel on my blade (which is honed at 20
degrees)? No matter how hard I try to figure it out, I just dont have
the head for geometry. Is it even possible using these tools or is
there some other way?

Thanks

Bob

By rotating the axle, you can change the angle by a couple of degrees
IIRC, not a full 5 degrees. I've found it's easiest to just do the
back bevel by hand. Lee's book shows putting a small block under the
blade a certain distance from the edge and that equates to 5 degrees.
I forget the details but I seem to remember something about "the law
of 60"? If you don't have the book, lemme know and I can dig out the
specifics for you.

My question is not how to use the guide. I understand that and use it
all the time. My question is how to put a 5 degree back bevel on a
blade using the 15, 20, 25, 30, and 35 degree settings. The blade I
have is honed at 20 degrees its front--now what guide angle do I use
to take off 5 degrees from the back-- see?

The original poster asked about a *back* bevel, not a microbevel on the
usual bevel.

Let me guess - you threw away the instructions!

The roller is on a axle that is offset. If the axle is rotated,
the angle of the blade is changed by several degrees. I haven't
used it in a while, but IIRC, just grab the ends of the axle,
push or pull it one way and turn it 90 or 180 degrees. If you
look carefully, you'll see what's happening.

The way I've been told to do it is to place a steel ruler or shim
along the edge of your honing surface. Lay the blade perpendicular to
the ruler and hone the back using a side to side motion. I haven't
tried it yet but that's the way I planned to try it. However, the
above method of placing the wheel of the jig on the table instead of
the stone sounds plausible.* I don't know if that will work but it
may be worth a try.

Cheers,
Mike

*This approach may be difficult if the goal is to make a 5 degree back
bevel. My goal will simply be to simplify the process of polishing
the very end of the back.

you can't. I have that same guide, Bob. For the 5 degree
back bevel you'll have the the tool on it's back, elevated a
mere 5 degrees.. the guide can't be used for that...unless
you place the guide on the table and the blade on a stone or
other elevated sharpening surface such as sandpaper on an
appropriately high block.
