12 Steps to change your bandsaw blade
The first thing you need to remember when changing your bandsaw blade is tracking the blade before adjusting the guides, or you will need to adjust them again later. Keep in mind that blad tension affects tracking so you need to first bring the blade up to proper tension.
Here are 12 steps to change your bandsaw blade according to “Lonnie Bird – The Bandsaw Book”.
- Disconnect the power
- Release the blade tension
- Set the guides so they don’t interfere with the blade in any way – at the sides or at the back.
- Install the new blade, first on the upper wheel, then around the lower wheel.
- Apply just enough tension to take the slack out of the blade.
- Turn one wheel a few times to move the blade to the centre of the tire.
- Tension the blade with a meter, or if using the saw’s gauge, set the tension for the next widest blade.
- Track the blade.
- Adjust the upper and lower thrust bearing so they don’t quite touch the blade.
- Set the distance from the upper and lower guides to the blade with a scrap of paper or a dollar bill.
- Square the table to the blade.
