I am building a dust collection system for my
table saw. I have it just about complete, all
I have left to do is to build a blade guard with
a dust port. I can build one with a 3 inch or 4 inch
port in it and I would like some feedback on witch
would be the best size.
The system starts at a 6 inch line from the cyclone
and ends with a 4 inch line at the saw.
It will have a 3 foot piece of flex at the end that will
attach to the blade guard. This 3 foot piece can be
either 3 or 4 inch diameter. I have been told that the
3 inch hose would have more velocity at the end than
the 4 inch and wound be better for picking up the
sawdust that comes up the back side of the blade.
What do you guys think?
