Sherline Z backlash Nut/fix

Hey guys,
I found my z axis to have a whopping 0.26mm of backlash in it! After
some thinking this is how I fixed the problem. Not sure if this is
the "best" way but it works well.

I used the Z axis lock (came with the mauel mill) that they tell you
not to use when converting to CNC. I tapped it, then turned it so it
almost locks the axis (taking out the backlash) and then put a braket
to hold it there. My backlash on my sherline 5410 went from 0.26mm to
0.07mm! I also made the hole a little longer as to make the backlash
nut adjustable as everything wears down. I put a pic up case anyone
wants to see and try it. Its under BACKLASH.

So far excellent results!
