This picture (courtesy UK Carpenters Fellowship / @guillaume_tampier), of timber being scie-sawn at Amboise, France, demonstrates how additional height can be obtained on flat ground or over a sawpit pit can be obtained by using a timber bob upon which logs might have been be brought to the pit.
Another picture taken at Amboise by @guillaume_tampier showing how 11 people are needed to lift a hewn cant onto trestles. Very macho, dangerous, wasteful of energy and does not employ parbuckling. This is where Leonardo DaVinci is buried and doubtless he would have made similar comments.
Once on the trestles the cant is halved using a frame saw (OWG has one !).
Note that the girl is "top dog" due to her superior ability to pull the saw back up (different tummy muscle structure).
The man provides gravity assisted downward motive sawing power however occasionally it's time to swap places and cause a different set of muscles to ache !
A carpentress (without a hair out of place) sits astride a Millers Falls boring machine (circa 1900).
This hand cranked machine eliminates repetitive strain injury to joints incurred when excavating mortices using a mallet and chisel. You can also listen to the birds singing !
