How to Set Your Sewing Machine Tension to Perfection

 — Tension disks and a tension regulator are part of your sewing machine's tension assembly. It is through tension disks that the thread passes before it reaches the needle that it is tensioned. Tension is created by the disks squeezing the thread. Tension regulators control the amount of pressure exerted on threads by disks.

 — The yield strength, for these purposes, is defined as the tensile stress required to produce a total elongation of 0.5% of the length. However, the case of P–110 casing is an exception where yield is defined as the tensile stress required to produce a total elongation of 0.6% of the length.

Setting Bandsaw Blade Tension

 — A tension meter is the most accurate way of setting the blade tension. If you own one of the many consumer bandsaws with a wheel diameter of 14 in. or less, then I would use a blade no wider than 1/2 in. for resawing and tension it until the tension spring is nearly compressed.

It is essential that it has some means of distributing the pressure over a small area to avoid damaging the table.

Setting Bandsaw Blade Tension

Bandmill Blade Tension and Blade Temperature

The tension force could be delivered by a spring, air, liquid, or even weights. Any of these should be insensitive to environmental changes. There would be a problem if your mill manufacture uses a tension system that the energy to produce the force is switched on for only part of the time the tension is needed. Shame on them.
