Historic Woodfinishing Workshop Day 2
The primary work of Day 2 was building up the finishes in preparation for the rubbing-out and toning of the final day.
The first task was to scrape the large shellacked panels with disposable razor blades to get them smooth as silk for the final application session to follow. True enough, disposable razor blades are not historically precise but scraping is, and using the disposable blades is the best way I can get the process integrated into the workshop. If done carefully the resulting surface is pretty much a flawless ground for the final layers of varnish.
We then moved on to some tables legs to get a little time in on working with “in the round” components. These are often a challenge for inexperienced and old-time finishers alike, but one key to success in this regard is a light touch and the right brush. I’ve found that a rounded-tip brush, sometimes called a “Filbert mop” with good bristle drape results in a near-perfect application every time.
The fellows worked so fast we had time to insert a couple of exercises, one being the use of molten wax on tables legs. We let a hair dryer substitute for a red-hot poker, but the results were acceptable.
Raised panel doors are also a sometime headache, but once you get the hang of the routine it works out pretty well.
Finally it was time to start on the spirit varnish pad polishing, a/k/a “French” polishing. Each of the students constructed their own pad from cotton wadding, then charged it with the spirit varnish. (This led to a fairly involved discussion about the fabrics that are best suited for which tasks in the finishing room. I asked my long time friend and Roubo colleague Michele Pagan, a textilian for as long as I have been a woodfinisher, to write a blog post on the topic. I will post it probably next week.)
By tapping it on their palm they knew when it was ready to go. And, it gives a lovely sheen to the palm.
The boards they had prepared on Day 1 were partially wax-filled and partially raw-but-burnished wood. Since so much of spirit varnish polishing is “feel” there was not much to do but turn them loose.
Before long there was a-glist’nin’ all over the place.
Another exercise that frankly I have never been able to get perfect was to fill the grain with beeswax and powdered colorant, pressed in to the wood grain with a polissoir. I need to work on this concept a little more, although Roubo promises success.
And with that we were done with Day 2.
