no previous part Part 1 of Upgrading circular saw dust extraction series no next part

I bought a circular saw with a sliding table from China a couple years back. It is a really great saw but some parts you could wish for more. One of the easiest parts to modify is the dust extraction. It does not work very well since the airflow is distributed all over the place. So the question was how to make this better. I friend of mine has a wood working shop there he work professional and with much bigger machines. So I basically paid him a visit and had a lock inside his saw how the dust extraction was solved there. I tried to copy that solution with pride.:-). One think I found to hard to integrate in my solution was cover that followed the blade up so the slot in the dust collector was closed when the blade was raised. I very rarely use my pre-cut blade in my saw so it was been removed in these pictures. With a good sharp saw blade for boards I see not much need for it.

Here is the old dust collector that is made in china.

I started out to make a the new dust collector out of cardboard so I could easy check that everything worked out as it should.

Cut the steel parts into the correct dimensions

Welded it all together, I have no roller for making tubes so I welded on a part for ventilations tubing.

Some paint.

It is now all fitted into the saw and it made a huge difference it extract the dust so much more effective.
