Abstract
Across North America the amount of tensioning used in bandsaws varies drastically. Sawblades tensioned to fit circle gauges from 28 feet to 80 feet in diameter are in regular use and performing very well. This raises the questions as to what is the right amount of tension and what effect does it have on cutting accuracy. In this study, the cutting accuracy of five sawblades, with varying levels of tension, have been measured and compared. The results show that little change occurs in cutting accuracy once enough tension has been put into the blade for it to fit an 80-ft circle gauge.

Abstract
The main objective of this project was to introduce NCC into the phenolic resin system as a reinforcing agent for improving the resin’s bond quality and durability in the manufacture of oriented strand board (OSB). The approaches adopted in this project can be outlined as follows: Develop a procedure or a new process technology to uniformly incorporate NCC into the phenolic resin system including phenol-formaldehyde (PF) and lignin-based PF resin; Develop new formulations for the NCC-phenolic adhesive system in both liquid and powder forms; Characterize NCC-PF and NCC-lignin-PF resins with differential analytical techniques; Manufacture OSB panels with NCC-PF and NCC-lignin-PF resins; Quantify the performance improvement of OSB panel by evaluating the resulting panel for physical and mechanical properties.
