I am trying to find information on the amount of crown to put on over hung (cantilevered) wheels as opposed to center hung wheels/ I have been told that it is imperative to use at least .003 crown in over hung wheels I have always put a minimum of .003 crown in center hung wheels although .001 per foot of wheel diameter is considered standard. We recently reground the overhung wheels on our Letsun Burpee 6ft twin to the headfilers request of flat wheels. They did come out with a very slight crown anyway but we are now experiencing a tracking problem with the saws. We have countered this problem by pumping up the front tire as well as adding a bit more tension and back which seems to have helped . In a recent conversation with Optimil techs. I was told that crown is needed in over hung wheels to counter the flex in the frame caused when the bandsaw is strained up. Out rig is a L/B USNR 6ft horizontal twin using 16gua. 44ft6in. x 10in. IKS saws with a black 40 tension and .012 (in 3ft.) back and 23,000 lbs strain. I would appreciate any information you can give me on this topic.
