Hi all; I use this mill to do precision wood carving too. This morning I had a 42" piece of Mahogany 3/4x11 clamped to the table, with a c-clamp tightened gently on the far end to hold up some of the weight & hopefully reduce the binding on the ways. It must not have worked that well.
Lowering the z home by small amounts to get the desired depth of cut, I noticed as it started the first cut that it was off about 20 thou from where it should have been. Ooops, hit esc. I though I had seen the motor turn without moving the table, so I powered down the motor supply, grabbed a damper and turned it. Very free and no table motion. My x screw is anchored into a socket which extends it thru the bearing boss and out to the motor coupling, and has a tapered thread I made on the lathe with g33.1 since unlike g76, it can do tapers in a circular nut and the od of the socket piece before its slotted, (no room for wrench flats in there) which I tighten till I am out of vice grip grip to tighten any tighter, drawing the slotted walls of the socket tight on the end of the screw. That _was_ the theory anyway... When I originally put it together, I had slathered it full of "just in case" red thread locker, which I had to heat to get it apart again but didn't on the last reassembly a week ago after redoing the nut holder to get rid of excess backlash because the nut (no flanges on that teeny ball nut) wasn't held tight enough. So now its full of thread-locker again and curing for an hour or so. The reason I am glad it broke when it did? That mahogany is $12 a bd/ft, or close to a $50 board. And I caught it in time that finishing the job right will cut away the miss-queue. Now I need to figure out how to do that with a bungee cord, which has more stretch than a binder strap. Needs to hold up about 6 lbs or so of board, nearly 4 feet out from the front of this toy. The life and times of an old fart in the West Virginia version of Lake Woebegone. My wife, when she makes a mistake, has to call all her friends and explain that inside, the doozey she just did proves she really is a dumb blond that was born with black hair. Maybe its catching? Back to your regularly scheduled programming folks. :) Thanks. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
