This is one of the most dangerous but also one of the most versatile woodworking tools.

Did you know you can also turn a rotary tool into a micro table saw?

Health & Safety

Unless we get our hands on a stopping table saw, this is a machine that can take fingers off or launch workpieces across the room. Take precautions to prevent the worst from happening!

Push Sticks

A simple wooden push stick came with the saw, but it's easy to make custom ones that may be more suitable for your project. If anything about the cut you're trying to make does not feel right, use a different push stick or ask someone with more experience!

Depending on the size of your workpiece, push blocks may also work.

Dust Extraction

Hook up the dust extractor every time you use the saw, and use the top blade guard whenever possible (it would get in the way when making hidden cuts or using the crosscut sled, but is useful in all other cases)!

Saw Blades

This machine uses circular saw blades with 250 mm OD/30 mm ID.

You'll need a large wrench for the arbor nut: it should be in the compartment on the right.

You can cut up to 80 mm thick workpieces on this saw.

Maintenance

The blade should be sharpened or replaced when it becomes dull, otherwise using it is very dangerous! Tell a manager or tutor if you are noticing any problems, e.g. increased force required to push your workpieces or poor quality cuts.

Decreased cutting ability can also result from dirt buildup - here are some cleaning tips.

Additional maintenance routines are found on page 16 of the manual.

Accuracy

CAUTION: Something in the height adjustment is not spring-balanced - the blade exhibits slightly different inclinations when being brought up than when being brought down. Make sure you measure this angle in the same situation every time!

Fences & Jigs

  • parallel fence
  • simple miter fence
  • sliding table
    • for angled crosscuts: used together with the miter fence and/or lever clamps

Additional accessories may be self-made or found on eBay or similar - the exact model is not made anymore.

Crosscut Sled

When making 90° crosscuts, it is highly recommended to use the sled that Lars built! With this accessory, the table saw can replace the chop saw in many cases.

To reduce friction, we applied paraffin to the underside of the sled and it seems to be fine so far. Otherwise we could also try some kind of very smooth adhesive tape.


Further improvement ideas:

  • safety block where the blade exits the rear fence - keeps fingers away!
  • adjustable rollers aligning the sled with the saw table from the right side

Miter Fence

For very precise angles, we could build a jig that holds the miter fence upright for setting its inclination with an inclinometer!
