The.Deflection.Method
The deflection method is much more subjective than
the flutter method. Each blade will deflect differently
and every user will determine what "moderate pressure"
means. The following are general guidelines for tensioning
the blade with this method.
To tension bandsaw blade using deflection method, do
these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Make sure blade is properly tracking as instructed in
Initial Blade Tracking subsection on Page 27.
3. Use handwheel to fully raise guide post (see Figure
39), and move upper and lower roller-disc guides
and support bearings away from blade (see Figure
40). Refer to Page 33 for more information.
4. Engage blade tension quick-release lever to apply
tension to blade.
5. Using moderate pressure, push center of blade
sideways.
— If blade deflects approximately
tensioned. Proceed to Step 6.
— If blade deflects less than
tensioned. Rotate blade tension handwheel
counterclockwise two full turns and repeat Step 5.
— If blade deflects
tensioned. Rotate blade tension handwheel
clockwise to incrementally tension blade, and
repeat Step 5 until blade is properly tensioned.
6. Adjust blade guides as described in Adjusting Blade
Support Bearings and Adjusting "Euro-Style" Roller
Disc Guides on Pages 33–34.
