Stupid Roland DWX 51D hacks

    I've never liked how the tools were out in the open to collect dust.

    Yeah yeah I know the air nozzle supposed clean the tool before pickup but it just messed with my head.

    PMMA is the worst for this. Here's what it looks like after a couple bitesplints.

    So I grabbed a piece of plastic (cheap-o place mat used to pour models on), some package tape & three magnets.

    Here's what I came up with:

    In place

    And the results after a couple All on 4 Provisionals:

    The magnets make for simple on-off

    Doesn't your spindle constantly blow out air through the spindle and collet when no tool is in it?

    It should.

    Read the second line in the post :(

    DMC Look mom, One handed!

    No....that is an air-puffer which is not air coming out from the spindle. Right?
    I am talking about a second air line that pressurizes the spindle cavity.
    Not an air nozzle to blow dust off the parts during machining.

    When no tool is in collet you should have small amount of air coming through the collet.
    Doesn't the Roland have an air line going to the top of spindle?
    To help cool the bearings and blow out debris?
    Totally different thing from air-puffer thingy.

    Me too. Wet mill plastics.

    I like your thinking Kirk!

    Thanks for posting

    No air comes through the spindle, just constant (when running) air flow through hole beside of spindle.

    That's the reason for the shield

    Simple disposable tool holders, when you don't have a printer

    Make a mold out of PVS, silicone, whatever...

    Drop in a couple washers (so the magnetic tool holder can grab it).

    After cleaning up the top a drop of super glue holds it in place.

    Or design in cad and have Scott print them.

    Hmmm.

    Never seen a Dental Spindle missing the pressurized air in the spindle cavity before.

    Usually this is a MUST due to heat and keeping out debris from internal of spindle.

    Also, this prevents shit on shank of tool when collet opens and grabs the next tool!

    Well.....poop then I guess?

    I almost can't believe it. I want to see top of spindle.

    This cannot be true, is it?? :confused:

    There is nothing to see on bottom of spindle for all mine.

    It is a hose that usually goes to upper-side of spindle

    I know you "Almost can't believe it" Scott, but its true

    No air through the spindle, take a look

    Now does my Stupid dust shield make any sense?

    Sit down, drink a beer, calm yourself and soak it in, ha ha

    So what cools the spindle and keeps dust out of the spindle?

    Nothing?? Dang man. That's surprising indeed!

    Scott.....

    Why do you think the spindle has a 2000-2500 hour life expectancy? You know, when you're milling a little bit of everything.

    If only wax is milled it can more than double the life expectancy.

    If you're milling only PMMA you won't make to 2000 hours.

    When the spindle goes I'll probably just spring for the print head option :D
