Spinfire Furnace Stringing Machine

The Spinfire Furnace is the most advanced machine in the Spinfire range. This electronic machine has a "6 point self-centring suspension mounting system" which decreases the loading and unloading time as well as providing ample room to move under the string bed. It also comes with automatic base clamps (new improved design in 2020 not shown in above photos), high quality 5 tooth hybrid column clamps and 4 tool trays. It has the ability to set the pull speed (low, medium or high) as well as the pre-stretch value (0, 5, 10, 15 or 20%).

What makes this machine stand out from the rest is the auto locking turntable. Each time you pull a string, the turntable will lock automatically. There is no need to pick and choose when to apply the brake, it's applied automatically on every pull (it can be disabled if you prefer).

Furthermore, the linear gripper has two micro switches which trigger the pulling mechanism as soon as the string is gripped. Billiards (the 12 & 6 o'clock supports) are provided for both tennis and also badminton/squash, along with optional load spreaders.

The height adjustable stand is included as a standard feature, however it comes with rubber feet pre-installed for conversion to a table top model if that is your preference.

How to string a tennis racquet

If you want to learn more about the process of stringing a tennis racquet, please watch the videos below.

When stringing we recommend using the Pro Knot. When done correctly the knot is very compact with the end of the string neatly tucked against the frame. It is fast, easy to do, and very secure with no spillage or breakage issues with all string types.
