Here’s how I make these applied turnings. Other people use other methods. I did not devise this method, but I think a few of us came to the same conclusion at the same time. I first stumbled onto this method in the mid-1990s, and I recall discussing it with Alan Miller back 20 years ago when he, Trent & I wrote a long article about Essex County (Massachusetts) cupboards that use lots of applied decoration. http://www.chipstone.org/article.php/554/American-Furniture-2001/First-Flowers-of-the-Wilderness:-Mannerist-Furniture-from-a-Northern-Essex-County,-Massachusetts,-Shop-
The concept is: How to get a pair of turnings that consist of just under-half-cylinders. There’s lots of ways to get there, but when using period style tools, including a pole lathe, there are challenges. Some turn a solid, saw it in half, then clean up the flat backs with a plane. That’ll get you there, but how to hold the piece for sawing & planing?
I do it this way. My first step is to glue up a turning blank with a spacer between the two halves. The spacer’s true function is to provide a solid material for the lathe’s center points. Without it, the centers are driven right into the glue line, and acting like a wedge, they can split the piece apart too soon. I know this for a fact. Remember, “Good Judgement is the Result of Experience, and Experience is the Result of Poor Judgement.”
I don’t use hide glue enough to bother keeping a glue pot running. The past week or so there have been some damp and some cool mornings, so I lit a fire in the stove. Perfect, I’ll heat up some glue while I’m at it.
Once the piece is glued up, I mark the center in the middle of that strip, in this case oak. Then scribe a circle.
Next, I make it octagonal; these short ones I find it easiest to hold them between bench dogs in the cabinetmaker’s bench. I’ve done them loose on my joiner’s bench, but this way is easier.
and then turning. I used to do some turning every day at my old museum job. Visitors to the museum would want to see the lathe work, so I’d stop what I was doing and show them. Now, weeks can go by without me touching the lathe…makes for rusty skills. I can see why people would like turning rosewood, it takes detail very well, and burnishes like no native wood I know.
But like I said, I’m out of practice. These two are OK, but need to go back on the lathe to be thinned down. For their length, (6 1/4″ long) they’re too chunky. Makes their proportions out-of-whack.
