I'd like to hear some opinions. All the material i've seen in regards to guide pressure shows the top and bottom wheels having a common centerline (the wheel faces are plumb) or that the top wheel is set "back" from the saw line to create giude pressure on the top guide. In ther first arrangement top and bottom guides are off set to create pressure. In the second arrangement the guides are in a plane parrallel to the bottom wheel face and the op wheel is rolled "back".
My question is - in a bandmill where the top guide adjusts according to depth of cut is there any special consideration given to top wheel position and guide offset?
The guide travels at a fixed offset but the angle the saw leaves the top wheel changes. The lower the guide position the lesser the angle it leaves the wheel. The higher the guide moves the greater the angle becomes.
I'd love to hear any thoughts on this matter, Thanks!!!
