Alpha HW615/Ambassador C14 Band Saws: How Much Tension Can Be Put on a Blade?

Proper blade tension is critical for bandsaw performance, particularly when using wider resaw blades. Both the Alpha HW615 and Ambassador C14 are capable of delivering approximately 47,500 PSI of blade tension—providing the stability needed for straight, accurate cuts and reduced blade deflection during heavy resawing.

Measuring Blade Tension

The tool shown in the image below is a Lenox Bandsaw Blade Tension Gauge, which is one of many options available from various distributors. These gauges come in different formats and units of measurement (e.g., PSI, bar), so it’s important to choose one that suits your needs.

✅ Proper Tensioning Instructions

To correctly set blade tension:

1. Consult your tension gauge's user manual for setup procedures and calibration.

2. Calculate the required tension based on the width and thickness of the blade you're using.

3. Adjust the bandsaw's tensioning mechanism until the desired pressure is reached.

Always verify tension settings before operating, especially when switching to a different blade type or size.

For best results, follow both the blade manufacturer’s and tension gauge manufacturer’s recommendations.
