Well, thanks for that Floyd. I learned something important today. See the shoulder on the nut. (The right nut has no shoulder and does completely tighten.)

I found that out recently when I had to bring a machine back to life. Subsequently we call it frankencarve. I wasnt really sure if that is how it was supposed to be or not. So I kept quiet but now I know. Thank you as well.

I cannot verify that it is supposed to slip a little. Both my B machines seem tight. At least they do not move when cranking up and down. I will have to dig deeper before I can say for sure.
Chris Rawls was the one who gave me the info.....

Hmmmmm !!!! Interesting ,, Still stuff to learn ...
Mans Quest for knowledge,,, means he'll always find a way !!
A inspection of the underside of the machine is in order... Remember to un plug the power.... We don't want to ZAP users....
The Cross Conect 45 degree gears have a screw holding them together and it sometimes gets loose letting the gears slip...
Rememeber 2 methods of checking head level.... ASKBUD's put 2 boards under the heads one on each side with a strip of paper on top of each. Tighten down the head and pull the paper... If one comes out easy... It's high....
And 2. Same setup but use a bit and Z Data to measure the touch to the wood and read the LCD.

Yes it is true. I just took one apart to see. My theory about the backlash is wrong. It does not rotate much. The nut is free to "wobble" in a larger hole. I think it is so that there are no stresses when the head moves up and down. The gear mechanism at the top has to hold the end of the threaded shaft and that could cause a bind if there was no freedom. (On the other side there is no crank and there is some freedom for the top end of the threaded shaft to move.)
