Hello all,

I have the standard $15 sharpening guide that seems to be rebranded by just about everyone, mine is by Robert Larson. I shad some trouble with it holding my bevel chisels, but found a video by Lie Nielsen on how to tune the guide. So i did that and it works MUCH better now. But I am still having trouble sharpening my 1/4” bevel chisel with it. Seems no matter what I do it wants to sharpen at an angle. Any tips or anyone else have similar issue with the smaller chisels?

can you post a photo of just how you have the chisel clamped in the guide ?

Lets see if these post up ok. I tried to get clear pics of the angles, hopefully the lighting is ok. I think the problem is the 1/4 chisel doesn’t have wnough bevel to catch the bevel of the guide but not sure what to do without risking ruining the guide. Works perfect with every other size. But I am starting to make handcut dovetails and need the 1/4. Btw that shiny part is the microbevel at 30 degrees. Thanks!

I have the same guide as you but don’t think I have ever used it on a 1/4” chisel.
I just put a 1/4” Buck bench chisel in mine and there is no way I could get it firmly
seated in the guide, just as you are experiencing.
if you want to use the guide, you could grind the sides of the chisel to fit the grooves
of the guide – not cut the guide itself.
or – make some kind of homemade jig for the small profile chisels.
I rarely use anything smaller than a half inch so I never noticed the issue before.

I just roll with it. If my eye can’t tell it’s not 90deg it’s close enough.

Try putting some blue painters tape on one side of the pivot wheel to correct the skew. Once you establish the bevel at 90, free-hand the rest.

Had same problem. Gets worse with smaller width chisels.
If you insist on using a guide:
Either have to change chisel side bevel with grinder to match honing guide, modify honing guide dovetail slot to match chisel, or do what I did – toss that cheap guide in junk drawer and get a Veritas Honing guide.
Problem with differences in chisel side bevels disappears with Veritas MKII guide.
Lie Nelson produces a honing guide with interchangeable jaws to help solve tool fit issues as well.
YMMV

Thanks all. I may grind this chisel a bit. Its an inexpensive Marples, so no biggy. Maybe i can grind it to also index it at 25 and 30 also to save some setup time. I’ll post back once i try it.

Those eclipse-style guides are pretty cheap. Maybe just grab a second one and re-grind the dovetails to fit smaller chisels?

Wrap some sandpaper around the chisel run it through the guide may just be some casting goobers sticking up. A little hand pressure to one side can correct a lot of it as well.
