    Default Vacuum Nozzle

    Finally got around to finishing the vacuum nozzle for my Desktop. It allows for me to "See what I'm cutting" Fully adjustable and gets 80-90% of the chip.

    I STILL had static on the 98% RH humidity days this year that would lift the hairs on my arm when using the non-grounded Fein hose for cleaning sawdust behind the machine Ron
    AND try to keep shop around 50-60% with a dehumidifier to keep woods stable(except when it would raise temps too much like during our record July).
    Seeing some nice work out of your Desktop Ron!
    keep cutting!

    That is a really interesting design. Can you tell me a little about why you didn't stick with the brush skirt design?

    First, why I didn't stick with the skirt design: Mainly because I like to see what's cutting.

    Second, How effective is it: Vacuums up 89-90% of the chips if adjusted properly and you have a good vacuum source. Yes it does take a little more setup time than the brush skirt but what the heck this is a hobby for me and not into production work.

    Third, More details.....
    See the attached images for the parts.
    For the nozzle I put several layers of glass cloth/epoxy resin over a foam mold I carved from Big Box foam board and sanding between layers. I then poured acetone into the nozzle to dissolve the foam.
    A two part female mold would not have required sanding between the layers however, as this was a one off part I couldn't see going to the trouble/time of making the two part mold.
    It's fully adjustable to obtain the best chip removal for different bits.

    Oops, that’s 80-90% not 89-90

    Just a thought, I believe that if you attached a skirt that only enclosed the area near the router, not the whole mount, you might increase the performance.
