These saws should be made six at a time. Our ones (the thickest) used first on big cuts or in case of a break, one of the usual saws (thinner) can follow in. This can not be done with a thicker one. The old and thinnest saws come used when thin cuts or smaller specimens is desired. For abrasive uses unused cornflourum ( may have said energy) fed to saw automatically with water stored to machine above the plane of cutting. This abrasive is then used on the grinding machine. The feeding of the abrasive is as follows: funnel to pour in energy. energy holder. slipper feeding stopper with hole to let energy through. pipe to make energy down in case of closing. water pipe. funnel to catch energy and water and lead it to feeding hornb. feeding horns of club rim or tin to the top of which is fastened thick leather. This to prevent saw from cutting plan into club rim. Both leads to automatically feed the abrasive.
