While out walking today i had a sudden thought about Spanish fell walking boots. Can any of you remember them? They were suede leather with a rubber sole. Not much there to go off,but they were simple things. Quite flimsy and in either dark brown or beige,if i remember rightly. I'm talking 1970's here so i think they cost about a fiver a pair and usually bought if i remember rightly again at army and navy surplus stores.

I'm half an hour into a power cut here. It started when I was in the bath. That was an interesting extraction from the bubbles.

I was wondering how you made it only twist on one plane instead of turning into a pretzel, that makes sense.

My carpentry tutor spent hours torturing us with whole pages of tables giving warping percentages for all the common hard and softwoods in all three directions, and a set of formulas which theoretically meant we could calculate to tenth of a millimetre how much wood would twist in a certain direction for a certain temperature and humidity. We did at least two examples a week for two and a half years and every test had at least two questions on the matter.
Thanks for explaining that ! I could never understand when I was at school why a piece of wood that I had planed so carefully had totally altered by the next week's lesson. :wacko:
Before anyone asks, no. I couldn't do it now: on the day after the exam I quite happily forgot the lot.

I since asked a British cabinet maker of some repute how they calculate twist. He said "Softwoods 10%, Hardwoods 5%. Done."

If your school was like mine this is because they stored the wood in a damp place and then used it in a dry classroon, and compounded this by stacking projects so the air couldn't get at both sides of the wood, causing it to dry unevenly over the week.

And using pine, which is cheap but warps for fun.

There are other factors as well, and they are generally ignored too.

This is unfortunate because you end up with a lot of people thinking they are stupid or incapable, when actually they simply aren't properly taught.

A friend of mine is currently trying to train carpenters in Rwanda, and says a lot of his time is spent trying to convince business owners to allow wood to dry properly (which takes years in some cases). He tends to be ignored and then the same people come asking why their furniture goes bendy.

Yes I think you are right. It was nice smelling the resin in the pine wood but at times your hands would become very sticky!
