The wheel is probably man’s most important technological discovery. A Sumarian pictogram dated 3500BC is the earliest reference for the wheel. By 2000BC man was making spoked wheels yet the earliest pictorial reference we have of a wheel driven lathe seems to be from the 15th century.
The great advantage of a wheel driven lathe is that continuous and controlled rotary motion is possible. This was not an automatic benefit to every aspect of woodturning though, as is illustrated by the continuing use of the reciprocating bow, strap and pole lathes. These ancient, simple lathes could still compete and perform efficiently in certain specialist areas such as small spindle and bowl turning. Continue reading
From classical times man has harnessed wind and water to work heavy machinery, to relieve him of hard physical labour and to speed up production. A Roman settlement C.200AD in southern France boasted sixteen water mills for grinding corn. It may be that this form of motive power was used to drive lathes also but if it was there seems to be no record of the fact. If this were the case, it would have probably have been the exception rather than the rule.
It does appear that the woodturners of old were content to continue with their tried and trusty traditional methods long after other sources of power were available to many of them. There were good economical reasons for this. No advantage was to be gained by expensive investment when the simple reliable technology of the strap, bow, pole and latter wheel lathes was usually just as efficient and more reliable.

Man has always tried to find ways of making manual tasks easier and the businessman methods to reduce manpower, speed production and lower operating costs. A good illustration of this was the manufacture of rifle butts. Hand held firearms have existed since the Middle Ages and virtually all these weapons incorporated a hand fashioned wooden butt. Making rifle butts was a highly skilled and time-consuming occupation and in time highly protective guilds were formed and prices kept at a high level.
This was just the sort of situation where a machine solution would be welcomed by firearm manufacturers, and in 1820, an Englishman, Thomas Blanchard designed a ‘reproducing lathe’. Blanchard’s lathe was capable of making two rifle butts an hour and it was not long before he had built one capable of producing ten or twelve in an hour. He went on to devise other reproducing lathes to manufacture shoe lasts and axe handles. Continue reading
