This bit of jig it has to turn thru about a 180, is on a section of piano hinge, about a foot long and about 3/8" thick and 1 1/2 wide, fairly light bit of Mahogany scrap. The whole thing might weigh 3 ounces if the piano hinge can be ignored. And if the drive belt hasn't stretched in its senior years, there is a surprising amount of pull to open or close the tray. The coupling cable I think can be a 6 or 7 inch length of speedometer cable. It will take 3 circuits (pins) of a parallel port, one to open it, one to close it, and one to energize an air hose to clear the area of old cuttings so it lays down flat with an audible slap each time. And yes, better dust collection is on my bucket list. But that will take more horsepower. Horsepower that to be economical, will need a 4th ciruit to turn it on and off as needed as the program is running. > Gene Heskett wrote: > > I just have to make an > > appropriately sized box with only 2 tight fitting holes in it, > > How about making a fan out of the spindle motor to keep > the dust out of the box by filtered pressure air ? > (I mean ... as we are already at it ... :)) > > > Have a nice day :) > > Thomas Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
