What Causes A Bandsaw To Cut Crooked
As specialists in bandsaws, our team here at EPS Services & Tooling have had our fair experience with badly cutting blades. It’s probably one of the most asked questions we receive – why is my bandsaw cutting crooked? To help future customers and provide information to support every woodworker, we thought we would delve into our blog by answering this common query here today.
We are passionate about the importance of maintenance when it comes to any type of woodworking tool. The demands placed on these items are extreme – especially when cutting through thicker or tougher variants. And, to ensure good value for money and reduce the need for regular replacements, you should always maintain your bandsaw blade properly. To do so:
- Clear the debris from the blade after use. Blow or dust off sawdust and make sure the blade is stored clean.
- Remove rust, first and carbon dust quickly.
- Clean your bandsaw blade with a wire brush.
- Lubricate your bandsaw regularly to ensure smooth working.
Crooked Bandsaw Cutting
Even with the most rigorous maintenance regime, you may still find that your bandsaw blade cuts crooked on occasion. The reasons and solutions for this are:
Your bandsaw blade should always be sharp. Over time, wear will cause this to dull out and, as a result, you will not be able to achieve such a precise cut. To pass through timber when dull, you will need to apply an excessive force which can cause it to twist either left or right.
Check that your bandsaw blade is installed properly. The blade teeth should be pointing in the right direction and it should be secured appropriately. If the teeth are facing the wrong way, you will notice a significant lag in the quality of the cut.
Bandsaw blades need consistent tension to ensure they can cut straight. Without it, you are likely to have difficulty staying on track. In general, this should be between 12,000 to 20,000 PSI with tensions over 35,000 not recommended.
Sometimes, you need the support of a professional woodworking company to identify the specific problem.
