Pictured: A teabox (10 3/4 x 6 x 4 1/2) that will hold about 60 teabags. The top is Movingui from Ghana and the sides are Black Cherry from a board I have had around the shop for almost 30 years. It features a mortised, full-length hinge, carved finger lift, corner splines, and lift-out dividers made from a wooden Venetian blind.
As you can see my shop is stocked with lots of potential boxes. Storing dried wood on end lets me leaf through it to get at boards. 14 foot high ceilings help.
Finish Steps: For me, one of the most exciting steps in making a box is the instant where I apply the first coat of finish. For the first time you can really see what the box is going to look like. I call it crossing the finish line. The wood shines, and the depth of the grain pops out. It is magical.
Like all finishes, preparation is the key. I don’t think you can rely on the finish to make rough wood smoother. You have to sand it.
It is quicker for me to have several sanders than to change paper. The steel plates and edge boards let the router spin down while I pick up the next grit.
First the boards are planed. Then run through a dual drum sander. Once the board is cut to width, rough length, and has the dado cut for the bottom board of the box…final sand the side of the board that will be the inside of the box. You can’t sand the inside of an assembled box. Start sanding with a random orbital sander using 80 grit to 120 grit to 220 grit to 320 grit to 800 grit. That is the sequence that works for me. The 800 grit is on a pad sander because the pad sander is easier to manipulate. The power strip plugs into a relay that automatically turns on the vac whenever any sander is turned on.
Once the box is made, I sand the outside surface through all the grits above, blow it off with an air hose, and wipe it off with a soft cloth to remove all the dust I can. Finally, I can apply the first coat of finish.
First Coat: Minwax Tung Oil. It is applied with a 1 inch foam brush. Allowed a couple of minutes to soak in and then wiped off with a paper towel. If you let it get too dry, it will grab the towel, just recoat the box lightly and wipe down. Allow at least two days for the oil to dry and harden.
Second Coat: Minwax Wipe-On Poly. Make a quick pass with 800 grit over all the flat surfaces and lightly rub all curved surfaces with 0000 steel wool. Blow off and wipe off dust and apply a coat of wipe-on poly with a new 1 inch foam brush. Dry the brush on a paper towel and very lightly go over the vertical surfaces with a dryer brush to pick up any runs. Let dry for one day.
Third Coat: Sand, rub, dust, coat with Wipe-On Poly for the second time. (I seldom need to do this step a third time, but if the wood is especially porous or rough grained I may.) Again, use a new foam brush.
Fourth and Final Coat: Johnson’s Paste Wax. I keep a pad of 0000 steel wool inside my can of wax. It won’t dry out and I can simply remove it and put a coat of wax on the box. Rub fairly firmly, but not enough to go through the finish. Don’t over do it a little wax will go a long way, and you are going to rub most of it off anyhow. You want to let the wax harden for about two or three minutes. If you wait too long the wax is harder to buff out. Rub the box with a rough cloth like a towel or sweat shirt. The goal here is to spread the wax evenly and remove any extra wax. Finally use a soft cloth to polish the wax. Rotate the cloth and wipe fairly vigorously to let the friction help smooth the wax. You’re done, and I am exhausted from writing this.
Thanks: As always thanks for looking. A special thanks to all of you who take the time to comment or ask questions. Check back, I will respond to all of your comments in batches usually three or four times a day for the next couple of days. Keep boxing and keep posting.
