Medieval woodworking part 5: pole lathe

Medieval woodworking part 5: pole lathe

No demonstration of medieval woodworking would be complete without a pole lathe.

I have spent quite a lot of hours this summer building an adapted version of Roy Underhill’s double spring pole lathe. It’s by no means medieval but it demonstrates the concept. And it doesn’t require a 20′ long sapling.

Yesterday was the culmination of the work I have been doing. I spent several happy hours demonstrating joinery and pole lathe turning at Fen Ditton 800. It was an exceptionally successful, well-organised and enjoyable event and I was delighted by the reception my little stand got.

While I was setting up a gentleman in his seventies arrived and started asking a lot of very astute questions. It became clear that he had been a joiner for most of his working life and he was delighted to see someone working with hand tools. We spent about fifteen minutes talking about his career, the huge workshop he had spent much of his adult life in and, inevitably, the decline of crafts and trades in the U.K. He set the tone for the day: interested, insightful people testing and extending my knowledge in the nicest way possible.

 

Treenails

Several of the chests I’ve used to inform this demonstration have been put together with treenails (trenails/trunnels/pegs etc.) I’ve used pegs for drawbored mortice and tenon joints quite a lot. A dowel plate is traditional for pounding them to shape and I’ve had some success with this method. It’s noisy work and sometimes I don’t get the straightest pegs but it does have one structural advantage – the pegs follow the grain of the timber.

IMG_0795Last summer I visited the Viking Centre near Ribe in Denmark. I was delighted to see them using an identical method but for much larger pegs. Their living history exhibits draw on a substantial body of research and I’m assuming that there is evidence that this is historically accurate. I’d welcome your corrections if I’m wrong.

However I rarely use the plate anymore. For this task I’ve chosen the “workmanship of certainty” over “the workmanship of risk”1. Partly because it gives more consistent results, partly because it’s a lot quieter but mostly because I get to use a really great machine!

Pegs through scarf

Boring the holes at an angle draws the scarf together. So they say.

In the interests of full disclosure: some of the treenails used in this chest will be pounded out by hand in a thoroughly medieval fashion but most of them won’t be…
