Should I finish the inside of cedar lined blanket chest lid?

Yes, finish it, to equalize the stress to prevent warping.

I built a cedar lined chest out of cherry finished with polyurethane (except for the cedar of course) more than 20 years ago, and the finish still looks great.

I think I would finish the underside of the lid, and I’m sure I wouldn’t use any oil based finishes like a varnish on interior parts. The odor will be there forever. A shellac or water borne finish will do well, and not have an odor problem. You could also use lacquer, though I avoid it due to the fumes.

The varnish will off gas for a very long time, maybe over a year. If things like food (kitchen cabinets) or fabrics, especially those made with natural fibers like wool are stored in there, they can take on that odor (DAHIKT). It makes for a very unhappy LOML….(LOL).

I made my lid with 3/4”plywood veneered with oak then i warped it with 1”solid oak leaving a 1/4” space for tung and grooved cedar.I think it makes

a nice touch.Look under my projects for my cedar chest I have made 2 this way.

”The varnish will off gas for a very long time, maybe over a year.”

I disagree. I finished a 12 drawer chest several weeks ago that is finished inside and out with Minwax polyurethane (see my project list), and the drawers are unfinished aromatic cedar. The inside had 3 coats, and the outside about 7 (I lost track).

By the time I finished installing the drawer slides and making final adjustments any varnish odor was gone. In use, the only smell is that of the cedar.

Thanks for all your insight. I’m inclined to finish the underside of the lid, though hadn’t thought of using shellac. Most of the interior would be unfinished and lined with cedar.

Thanks again.

Joe, I have had the same experience with Poly, Spar smells for slightly longer.

I highly suggest you leave the inside, even under the lid, unfinished. I have built several trunks lined with cedar. I make sure everything that is NOT aromatic cedar is finished. I put no finish on the cedar that’s on the inside though. I do this for several reasons, and each of these reasons I learned from doing it, not just from reading it somewhere.
The aroma in aromatic cedar comes from oils that are in the wood. While this creates a much sought after smell that also repels against moths and other critters, I have found that it also creates havoc with certain finishes. The oils sometimes makes finishes seem blotchy, even long after they’ve been applied and cured. I know this sounds crazy. You’d think that after a finish cures that the tone of it is there to stay. Not so with aromatic cedar. I have thought about this and I have a theory. I think it’s the oils from the cedar accumilating under the finish that just eventually overbears whatever finish you used. I have even tried shellac with great results in the beginning. Over time though, even shellac had problem. There is only one finish I have found that works flawlessly on aromatic cedar, but it is labor intensive, Johnson’s Paste Wax. The one I built for my daughter mad out of all cedar with the outside finished with wax and the inside bare. It has ten coats of Johnson’s Past Wax which took me for what seems like forever to apply.
I also think that it is better to have as much exposed bare surfaces as possible on the inside of a cedar trunk. The more the better. As long as there is enough, and the trunk is left alone for long enough, then everytime you open it, you’ll get that wiff of that aromatic cedar smell. I feel that this is the number one reason I like lining trunks with it. For some of us, it brings back memories of trunks our mothers, grandmothers, or someone had. By the way, I found a different way to restore that smell without sanding or scraping and it worst also as sort of a satin finish if you apply it right. Oil of cedar can be purchased from several online suppliers and replaces oils in old cedar and, in my opinion, gives it a look of new satin finished wood.

You can also see two more chests I made with cedar lining here and here.

How about adding some attractive cauls? That might help. I’d stick with a water-based finish if you’re going to do it. Nothing worse than a cedar chest that smells like a mechanic’s garage.
