A chop saw is an electric miter saw (BE: mitre saw) and consists of a large circular saw and a sturdy frame. Movement of the saw head is restricted by a sliding rail which can be angled both vertically and horizontally ("compound miter").
For the hand tool capable of making only horizontally angled cuts, see miter saw.
This tool is broken (probably an issue with the carbon brushes) but we are preparing to get a replacement.
Safety
Always keep your hands clear of the blade path and use the machine's clamp and the back fence to hold your workpiece in place. Before turning on the power at all, make sure you understand how the saw head will move and double check that all restraints are properly and tightly adjusted.
Cutting angles
Miter angle (horizontal): left/right 45°
Bevel angel (vertical): left 0-47° right 0-47&
Adjusting miter:
- Losen locking screw in the front
- Pull "miter presetting lever" [12]
- can be locked up with a locking clamp [10]
- Move to desired angle (indents at 45°, 31,6°, 22,5°, 15°, 0°, 15°, 22,5°, 31,6°, 45°, 60°)
- tighten locking screw before cutting!
Adjusting bevel
- Losen the locking lever [13]
- The saw can now be tilted up to 45° to the left
- In order to tilt to the right (or further than 45°) the rotary knob [39] on the right needs to be turned to the desired direction.
- Push the locking lever back down
Blade
Our saw is designed for saw blades measuring 305 × 30 × 1,7-2,6 mm (OD × bore × thickness).
The currently installed blade is a Bosch "expert Wood" 305 × 30 × 2.4 mm one with 72 carbide-tipped teeth.
Noise & Dirt
If you are not alone, ask the others whether it is okay to cut for a few minutes as they may have to interrupt their project to give you room and to protect their ears. Although the saw is not extremely loud, it is definitely startling when you are surprised by it turning on in your back!
It's advisable to hook up a shop vac for dust extraction as the passive collector bags that typically come with this kind of tool are not too efficient. Even the shop vac will let a lot of sawdust escape.
Maintenance
The blade should be sharpened or replaced when it becomes dull, otherwise using it is very dangerous! Tell a manager if you are noticing any problems, e.g. increased force required to cut your workpieces or poor quality cuts.
Decreased cutting ability can also result from dirt buildup - here are some cleaning instructions.
Potential Upgrades
- The work rests are crap and should be replaced by something, e.g. T-shaped wooden supports, at the proper height (see issue #11).
- It's possible to create a "shadow line" indicating your cut location by carefully positioning an LED right above the blade. [1]
- There is a clamping point on the right side of the blade, but when you actually put the clamp in there the motor will hit it. Could be fixed by adding a compatible hole (or simply another clamp) about 10 cm further to the right...very smart design -.-
- we should get (or make!) a "10 Million Dollar Stick" to use instead of the built-in clamp for small pieces

Our Herkules KSZ 2100 is broken and will get replaced by the above mentioned Bosch GCM 12 GDL.

Martin brought in an alternative chop saw, which needs to be commissioned before it can be used.
If we can get it set up on the same height as the other one and with the fences in one line, both chop saws could be placed pretty close to each other!
This tool is not ready for use yet since not all commissioning steps have been completed. The process is not yet tracked on GitHub. Feel free to contribute to making it usable, any help is very welcome!
