I think about improving DE from time to time (whenever I'm cleaning-up
after a messy job) but don't seem to find the necessary tuit. My saw has
a small hose from the crown guard (hinged on the riving knife) that goes
inside and joins the under-saw 50mm hose to come out to a 100mm port
that I connect to my 2HP HVLP cyclone extractor. I frequently operate
without the crown guard(!!) so plug the crown guard hose.
I'd like to devise a pivoting and self-adjusting crown guard that's
suspended from a hollow tube that's attached to the saw in some way and
can be used for DE. The crown extraction would be connected to the
under-saw hose with a throttle'able Y connection and then go to the LVHP
extractor.
Issues: how to make the suspension rigid enough (but allow the saw to be
moved), how to improve collection beneath the saw, ...
Suggestions and comments invited.
