April 15, 1919 CANADA LUMBERMAN AND WOODWORKER Waterous Bandmills are Best Much of the clear cut, business-like appearance of the Bandmill is due to the graceful yet massive design of the columns supporting the upper wheel. They are firmly fastened together at the lower end by heavy bolts and further braced by a through going steel shaft of large diameter. Located centrally on the bed, their wide bearing on the same, and the strength of their construction eliminates vibration and ensures steadiness and rigidity in the whole mill, even when doing the heaviest work. The raising and lowering screws, the tension device, and the tilting mech- ^^^â â m^^^ anism are all enclosed within the lower half of the columns, No. 5 Columns y^irx where they are kept quite free from clogging by sawdust, and in the best of condition. Both columns are recessed on their forward faces and the heavy posts which support the upper mandrel bearings work in special babbitted housings placed above and below the recesses. This method of carry- ing the upper mandrel is not only more rigid than the old construction, where the mandre was carried above the top of the columns and posts, but allows of a wider range of adjustment between upper and lower wheels, as the posts are held equally rigid at any height.
