Some will possibly disagree; however, the results speak for themselves. I prefer to use 600 grit paper to sand between coats of dewaxed shellac used to seal white oak:
As I have mentioned before, one key item in a finishing schedule is having the right sandpaper, like 3M’s 216U Fre-Cut™ Gold. I discussed the use of this paper in an earlier article; but I still must remember how critical it is to have the proper tools to do the job. And in finishing, this paper is an essential tool. The surface of the white oak is silk smooth after sanding. The smooth surface will telegraph into the sprayed varnish, yielding a very nice, smooth finish. Who said waterborne coatings were difficult to use?
Note: Sealing the surface of white oak and (especially) red oak is essential when using waterborne coatings. Avoid applying (typically) high-pH waterborne coatings directly on the raw wood surface of high-tannin woods like red and white oak, as pin-holing and bridging are likely to develop; that would make it difficult to get a nice, smooth finish.
Next: Attaching the top, and start spraying the varnish.

As I stepped out of the shop, I noticed the temperature gauge in the shade, on the wall of the wooden shed:
I had to look. Confirmed! I might be able to get away with spraying some lacquer today. The temperature was just above 40°F:
In the shop, on the outer wall to the finishing room, the thermometer has held between 66°F and 68°F for the last several weeks:
The remote unit, near the West wall, and on the lumber rack, showed a slightly lower temperature, but still acceptable to spray the finish:
In the finishing room, with all the equipment set up and ready to go, I started adjustments on the spray pattern, and air and liquid flow – I like to use craft paper as the target to make the adjustments:
During the Winter months I use a small ceramic heater in the finishing room; I use it to keep the temperature at 73°-74°F. It is powerful enough to keep the temperature in the room at 73°F with the 2,200 CFM exhaust fan running. In Winter I am typically limited to about 12-15 minutes of spray time before the temperature in the open part of the shop drops several degrees as the make up air comes in through a window. I should have waited until tomorrow, or the day after, to spray, as the outdoor temperatures will be in the high 40s; but why not today? Aw, heck, just get it done!
Following a short session spraying the lacquer, I moved on to preparing the pins I will use in drawboring the joints. I found a huge amount of oak dowels at the local home center, and proceeded to select those with the straightest grain (I don’t own a plate, to make my own pins). To minimize measurement errors, I decided to use one piece of dowel, pre cut to 2-3/4 inches, to measure all the others:
I have been readying the band saw for a presentation on resawing lumber to our Guild next week; as a result, the guides and blade are off the 17-inch machine. Why not use the Kenyon replica dovetail saw (made by Mike Wenzloff) to cut the pins to size? Of course! That made sense:
Some people prefer to cut with the dowel vertical to the workbench:
I had a great day in the shop. The outside temperatures and the sunshine have been a welcome addition to the time spent in the shop. Have you:
Drop me a note to let me know about your time in the shop during the last several cold weeks.
