in issue #161 there is a good article detailing how to conceal sapwood in cherry, with a sidebar that features a different technique for walnut.
I am working on a walnut piece right now and there is some noticeable sapwood (due to my own screwup, when I cut the tails on the top I did it upside down meaning my carefully selected boards that had no sapwood and perfect grain matching are no on the underside – doh!).
Rather than neutralizing the entire piece with a yellow dye, a darker dye and then glazing over a washcoat, I was wondering if I could use the cherry technique on walnut with good results. Feedback?

Black walnut hulls and ammonia can be used, I have read some place, maybe it was here on knots or in FWW mag.
I don't remember if it's green hulls or dryed hulls and soaked in the ammonia solution for several weeks and applied to the sap wood. I have some walsnut I need to test this on as well.
Thanks Tony. That sounds interesting but a lot of work... plus I'm always concerned about the reliability of these home remedies.
I just finished with FWW #200 and there happens to be an artical about what you are asking about using dyes.
I'm no expert, but had very good results with Jeff Jewitt's Transtint dye, no complicated schedule. Here's a link to the post and pictures. Might not be fancy enough for a table, but encouraging I would think. (i.e., if FG can do it, anyone can!)
I'm not even very adequate at finishing so I tend to do what's easy for me. But what has worked for me (at least to my eye) is onyx stain on the sapwood feathering the edges for a no-line blend. Wipe that off the apply walnut gel stain on top of the area blending into the darkwood.
I'm with Sam Maloof on this one - don't think of sapwood as a defect. Instead, think of it like a live edge - a design feature.

LOL, but I'll quote Woodman on this one: "when it just looks like crap the best thing to do is deal with it instead of excuse it."Thanks everyone for the advice. I did read that piece in issue #200 as well, which was basically a reprise of the earlier issue featuring cherry. My reluctance is that when I've dealt with walnut, which is not often, I have found dying the wood to be a little challenging as it relates to the sapwood. It's just always noticeable, which is why issue 167 and the neutralizing the entire piece with a yellow dye was interesting. I'll test it out on some pieces and report back. I'm not confident in the "just tint the sapwood and blend it in" approach, but I may be guilty of splitting hairs here as well, sometimes good enough is good enough.And yes, I do like the Transtint dyes, have quite a few recipes cooked up that rely on that line of products. Recently I have been using some of the Mixol tints and am quite impressed with them as well.
Last night I dyed a test piece using a neutralizing pass with lemon yellow dye, which actually made for an interesting effect with the walnut, but it more or less washed out the entire test piece. I then dyed the piece a second time using a dark mission brown dye and the sapwood did indeed achieve consistent color against the heartwood. I just laid down a washcoat of shellac but I think that with a topcoat (not a fan of poly but the application is a bathroom) this will come out rich and deep with good color from sapwood to heartwood. It's a little more work than simply trying to blend in the sapwood but I think the result will be worth it.
don't think of sapwood as a defect.
I agree.. But I like the idea of feather blending the sharp edge.
I look for wood like the 'problem' posted..
