The life of a bearing

I used a wooden framed, foot operated, treadle, potter wheel. It’s a very old ‘Leach style’ potters kick wheel. Designed by Bernard Leach, way back, early in the last century. That’s almost a hundred years ago, coming up sometime soon. This actual wheel was handmade in Australia under licence sometime in the 1970s. That makes it almost 50 years old.

When I started to learn about hand made pottery in 1969 I bought a 2nd hand ‘Leach’ kick wheel to get me started. I loved it so much, that I have used them ever since. I have tried other pottery wheels, but keep on coming back to this energy efficient, human powered potters wheel. Tragically that first wheel was lost in one of the two fires that have devastated our pottery workshops over the 50 years of my career as a potter.

The other day I was throwing a large pot of 3 kgs of clay. Not so big compared to what other younger potters can throw on an electric powered potters wheel. But about as big as I like to go on this old wooden treadle wheel. Well, I was pushing hard to get the mass of clay onto the centre, when ‘CRACK’ ! That was the end of my throwing session. I had busted the leather bearing that connects the foot treadle bar to the steel crank shaft. It was reminiscent of peddling your bike when the chain suddenly comes off the derailleur gears. Everything sins free and there is no response to the effort of peddling.

Now it just so happens that only last weekend I was at a ‘Lost Trades’ weekend market and exhibition and my good friend Warren, the guy who can do anything. Warren decided to buy a hand made leather belt. But his plastic card wouldn’t work on the ancient, lost trade, candle powered, banking machine that was available on the site, so I lent him some money to pay in old fashioned cash. The Lost Trades traders still have the ability to take cash! That is a skill that isn’t lost!

I asked the leather worker if I could have the excess leather from the very long blank belt was was being custom fitted to my friend. I got 300 mm of leather belt material. The leather worker, who I knew, knows that I am a potter, and I have bought my belts from him in the past. He asked me what I wanted the leather for. I told him about my very old potters wheel and its antiquated leather bearing. How amazing that the very same piece of leather bearing would snap just a week later. I am so lucky!

.As good as new – well almost

So I had to stop work and do a running repair. I was prepared. In less than an hour I was up and running again. I bought this potters wheel 2nd hand, after the last fire in 1983. The old leather strap had lasted 36 years! Not too bad for a thin leather strap.

I’m wondering how long this new one will last? I only used half of the piece of leather for the repair, so I still have another piece in reserve for 2055.

I’ll be over a hundred years old by then, so it probably won’t be my problem.
