Good evening all, I was in the shop listening to some tunes and turning a piece of aluminum earlier today. As I finished my part, I set the ol' Heavy 10 for threading 14 TPI on a 1" outside diameter. As I went about the usual set up, I got ready and began threading. Since I don't yet have threading dial, I stop the spindle and reverse to get decent repeatability. Today I noticed a bit of double threading on this coarser thread and went into a panic. So much for a relaxing hobby
My first reaction was indicating the halfnut. I found roughly .02~.03 play. The leadscrew had a .01~.015 shift. I knew I had some wear and it never bothered me much. I hardly ever thread at home so this hasn't been an issue before.
I was wondering if you guys think my halfnut play was the cause for double threading? I could probably shim the leadscrew and get most of the shifting taken out but I'm worried about the half nut. Is there a recommended place to get replacements?
