Saw Blades
Saw blades have to be changed frequently due to wear, different materials or simply because you want to cut a hole and have to enter the workpiece.
We use quick-release saw blades with pins on both ends, do not screw these in or they will break! Saw blades without pins have to be secured by screws on both arms of the machine. The teeth of the saw blade always have to point down and a hole will need to be at least 5.3 mm in one direction for the blade to fit through because of these pins.
Changing Saw Blades
- unplug the machine
- turn the tensioner (knob in the back) counterclockwise to loosen
- push the top arm down
- unhinge the saw blade from the top and bottom arm
- insert a new saw blade (teeth pointing down, pins carefully hooked in their grooves)
- turn the tensioner clockwise until the blade makes a high-pitch noise when plucked
- continue working

Your material and to some extent also the design you want to cut dictate which saw blades can be used.
Our scroll saw works with 127 mm saw blades which come in different versions:
- coarse (10 teeth per inch/25 mm)
- appropriate for soft and hard wood and thick materials
- Proxxon NO 28 741
- normal (18 teeth per inch/25 mm)
- fine (25 teeth per inch/25 mm)
- appropriate for plastic, glass-fibre reinforced plastic, non-ferrous metals, acrylic glass and wood
- Caution with acrylic glass: the material tends to weld the cut closed due to the high temperature being generated and thus prevents backward motion - make sure you will be able to cut in one go or you might get stuck! Consider drilling relieve holes along the cutting path to allow for easy turning and exit points. Also cutting straight lines into acrylic glass tends to result in wave-like patterns as the blade is flexible and therefore oscillates around the cutting path.

round (16 teeth per cm)
Repairs
We've had some mechanical issues with this saw over the years:
- 2020-10: loud noise due to the rotating counterweight hitting the bottom arm (near the motor) - fixed by Micha B
- 2021-5: tensioning screw losing contact to its nut due to a bent piece in the back - fixed by Patrick
- potential next problem: rubber collar around the tensioning screw (see issue comment)
