This report covers three days of testing on the primary breakdown line at the Pope and Talbot sawmill in Spearfish, South Dakota. Significant increases in production were achieved by using variable speed drives on the feed system and quadruple bandmills. By selecting rim speeds that provide the better cutting accuracies, this increase can be obtained with little or no increase in sawing deviation. In addition variable pitch sawblades alleviated washboard problems at all rim speeds tested and showed a small improvement in cutting accuracy. There appeared to be some alignment problems with the quad that were temporarily overcome by shimming the guides.
