From the last post you will be aware that I have built a Hood for my 12 inch Hitachi…
Basically this is a box made from 1/2 inch MDF….that sits behind the saw and catches any saw dust that is not directed to the 2 1/2 inch hose attached to the saw itself… where the bag is usually.
This hose is run through the back of the box and via a reducer connected to the 4 inch ducting system…
At the back of the box is a small plenum chamber with baffles…and a connector…
The angled baffles are cut to suit…
and then glued together… this box will fit behind the main hood.. there is a small gap left when the main hood is sat on the bench… dust is sucked through this slit…
This system was designed to allow the saw to pivot both ways to 45 degrees….
and a behind the scenes shot…
This system works extremely well … catching and collecting nearly 95% of the dust….I am happy with this… just a quick blow with some compressed air moves the dust that drops behind the saw towards the slit…and the last bit is sucked up as well.
I got the original idea here... thanks Blankman… I did however make a few changes… don't we all…
