Title
[N105073], Technical Note, Charles Batchelor, August 13th, 1880
Editor's Notes
Supposition about cause of carbon bending proved incorrect: "after a series of experiments...we came to the conclusion that whether heated slightly or to a high temperature some of each bend whilst others kept straight. We then rememberred that some bamboo fibres which were 4" long and of which we made a great number almost all kept straight we also remembered that almost all these were put in the clamps edgeways instead of flatways. This led us to see that the way Bradley cut them from the cane and the bending them flatways afterwards, would leave the `pith side' on one face and the `hard shell' side on the other face unequal shrinkage of course must occur on two such faces...." [Mott jrnl 8/11] Have made mould for carbonizing edgeways.[sketches] Another mould "with pin across to hold fibre tight so that it can pull the large weight down;" weights.
