How many coats are typically used on walnut or cherry?
Walnut oil is a great finish for utility pieces such as serving bowls, utensils, etc that have frequent water contact, because it sheds water pretty well and is easily renewed at any time by wiping on another coat and letting it dry. IMHO, there are better alternatives for most other applications where appearance is the important factor.
I concur with Dennis. If I use walnut oil, I just apply one or at most two applications within 12 hours. I don't like any more than that because I don't want an oil finish that builds on the surface. One application of walnut oil followed by a month to cure and then an oil based varnish finish does produce a nice glow.
Charles, what type of turning are you thinking about applying the walnut oil on or are you just asking about walnut or cherry wood? Perfsonally, I fvor walnut oil on light wood like maple. On darker wood, I might consider linseed oil or just a film finish. If it is treenware, then do like Dennis suggests.
I have a very dry walnut that will yield about 6 or more 8 inch bowls. Will probably be utility bowls for family use.
Try buffing after the walnut oil is cured. I use the Beall system. It produces a very appealing shine.
Well, I use the Doctor's Woodshop walnut oil now. I slop it on really thick, then sand out the next bowl. When I apply oil to that bowl, I also slop a bunch more on the previous bowl, and there are always some dry spots. I let it sit over night or two, then wipe off all excess. The 'microagregated' carnuba wax in the Doctor's oil leaves a really nice 'luster' to the bowl, and looks better than straight walnut oil, or bees wax. With the way he does his carnuba wax, you don't need speed or heat to get it to spread/flow, so you always get a nice even finish. Part of the reason I use it is because he is an Oregon boy....

Walnut oil is a perishable product...no matter where you buy it. The older your walnut oil, the more difficult it will be to completely cure. Polymerization (curing) and rancidification (spoiling) are competing biochemical mechanisms. The oxygen molecules in the oil break down the fatty acids that are needed for the crosslinking to make a solid from the liquid.
Walnut oil typically tastes rather bland, maybe slightly sweet and/or nutty tasting when it is relatively fresh. When the fatty acids break down (with age), the first by-products are aldehydes and ketones, and these by-products don't taste good. So, if your walnut oil leaves a disagreeable taste in your mouth, it's value as a "drying oil" becomes questionable. Just a couple of drops on the tip of your tongue is all that is necessary.
Taste it first, then decide where it should go.
