A883 2nd & 3rd question

Oh-Oh,busted!
I was only able to repoint the teeth on the gears he sent me.The 1-2 slider was minty. the 3-4 slider was beyond my current ability. My eyes just could not focus well enough at the cutting distance.The gears I mighta been able to do blind-folded.
So I supplied him with a minty one.
So my slider repairing days are over.
So to autoX,if you like, Id be happy to look at your work, just so long as its well lit but not washed out.
