GGG I usually try to buy wood with as little sap wood on it as possible. I have ended up with some walnut that has a couple of thin strips of sap along edges. Does any one have a preferred procedure to tone this down? Ed Minch |

Hey Ed, Just don't do it! Nice dark, rich walnut will lighten over time. Any stain blending of the sap wood you might attempt when the wood is fresh will not lighten the same way as the heart wood. You saw what happened to my work bench after exposure to sun for 10 years. I save any walnut with sap wood for inside skirts or drawer pieces where they won't show so much. Bill W.

Actually, Walnut heartwood ( the dark stuff) gets LIGHTER with sun exposure. The sap wood pretty much stays the same as when freshly worked. You could try a stain (start off light and work your way to dark) over the sapwood.... it will work, but over time, it will show as too dark.... The secret is to buy and build with as little sapwood as you can.... if you want it all the same color.... BUT.... if you are creative, the sap wood can be quite beautiful.... edges, or book matched to the center, create wonderful embellishments....

Frank Thanks for that. I got this wood from a friend in WVA who was closing a 30 year old shop where he used local woods to make “appalachian” sort of stuff. The wood was at least 10 years on the rack and $2 a bf, so I did my best select around the sap, but the pretty-dark top has a couple of thin strips of sap along the glue line beween the 2 pieces. I will use the analine dies that I am used to and not make the sap as dark as the rest of the top. And I don’t care for sap in almost any situation if it is contrasting with the heart. In guitar making, there are those that love the sap.

I understand that some commercial walnut is steamed. Apparently, this will cause the color to bleed into the sapwood (or even out, or something). Does anybody know details? I just get my walnut from Bill Webber. Thank way I know it's heartwood. (Bill, I'm still working with those pieces I got from you, in 2014 I think.) I don't use much walnut except for special projects. Gary Katsanis Albion New York, USA ---- Bill Webber |

Yes all walnut is steamed to balance the colour My daughter & son in law worked for a veneer company many years ago and all their logs sat in a steam bath probably overnight . Memory is getting a bit vague on that but I can still see the big concrete pit with steam pouring in where the logs were rolled into. Nick |

Ed, Another alternative is to use shellac to tone the sap wood and in 10 or 20 years when the color has changed on the heartwood, the shellac is easy to take off. I did this on a bedside table to blend in the sap wood. I used an amber shellac, then a garnet shellac with a little alcohol dye in it to match the rest of the wood. Worked for me. $.02 Brent Sent from my iPad |

262597 | Claudio DeLorenzi <claudio@d...> | 2017‑06‑27 | Re: Sap wood |
I agree with Brent. Sapwood takes color more than heartwood. Soaks it up. I often use pigmented shellacs- it's easy to adjust color, and if you don't like it, you can remove some of it with a denatured alcohol. Easy. Should be top coated with something tougher though. A good alternative to shellac: the pigmented Danish Oils (polymerized linseed oil plus thinner plus whatever proprietary stuff) also works surprisingly well to even out the color. Again, the sapwood seems to absorb more pigment. Try both on scraps first. That's the most important story of finishing. Do a scrap board, in sections, and record exactly what you did (including sanding grits if you sanded). This creates a storyboard of what you did, so that you can recreate that finish in the future if you create a complimentary piece. 20000 Canukistani Kopecs approx equal to 2 cents in USD Claudio |

Hi All, Just finished a Walnut coffee table designed around it’s sap wood. The base has no sap wood and is beautiful dark brown normal figured Walnut. The top has highly figure pillowed grain with some sap wood edges for contrast. I have used Watco Danish Oil on all surfaces and it POPS the grain, I need a highly usable top surface and am looking to use a glossy oil spar varnish finish on the top. Has anyone tried this?

Tommy, I've not tried that, but I have used several coats of thinned shellac well rubbed out, followed by two coats of thinned satin finish alkyd varnish. The table has taken serious use and abuse with no ill effects. My personal tastes do not run in the direction of glossy shiny finishes, but if desired, you could use glossy varnish instead of the satin finish. Can't wait to see photos! Cheers, John “P.S.

Agree, seal with shellac then you can top coat with whatever you choose. Sounds like a beautiful table. Pictures! Sent from my iPad |

A local cabinetmaker uses many coats of spar varnish (just a varnish designed to stay flexible so it moves with the wood in an outdoor location - I can tell you a good story) and polished it through the grits and with power polishers so it is gorgeous: http://www.viccovonvoss.com Having done my share of spar-varnishing, I would not have thought you could polish it so succesfully.

Thin your oil based varnish of choice and apply it the same as the watco, lots of thin coats.use fine sandpaper between coats. Unless gloss varnish, keep it well mixed in the can at all stages. I have come to prefer quick drying varnish for this process as I'm an impatient finisher.... ----- Original Message ----- From: "Linda & Tom Hall" |

I’ll try this thinner varnish process, are thinners all the same for an oil spar varnish? In time I would like to put a more appropriate base on it. From: bridger@b...
