Hello, I'm looking for some direction here. First off let me say up front that I am NOT a machinist, if I was, I guess this question would not be here.....My question is, how to set up the change gears on the CX701 lathe to cut threads? I'm obviously not interpreting the chart(s) correctly; plus, there are not any reference points, IE: Z1= which gear. Here is a link to the chart.
http://busybeetools.com/content/prod...uals/CX701.pdf (There is a pic of the change gears on page 23, and the chart is on page 27.)
I am trying to set up to cut 8TPI to make a threaded bushing, to me it looks like Z2 should be the 80 tooth with the 40 tooth as Z1 on the same shaft, with Z3 as the 30 tooth on the same shaft as the 60 tooth. However, the gears won't engage correctly if it is set up this way. Also, I can't figure out what "H" is at the top and bottom of the chart.
Any help would certainly be appreciated, folks.
Thanks in advance;
