Thanks to everyone for the information and views on 4" vs 6" ducting. I have another question regarding dust collection.
When using a scroll saw, fine dust is generated. This is exactly the type of dust most people discuss as being "the bad stuff" to avoid.
I have a nice scroll saw (a Dewalt DW788 20") and it comes with the standard flex-tube blower by which to keep the cut area clean.
HOW do I effectively capture this dust? The blower blows it off to the side and makes any underside suction less effective. I can't position a suction tube next to the cut since that it the work area.
This one has me stumped. Does anyone out there have a good solution to dust collection for a scroll saw?
Thanks again!
Jack
