It is with a very heavy & shaken up heart that I have to make this post.
I was in the process of threading the top half of a machinist jack (3/8”X16).
All was going well & I was in rhythm. Stopped to check the thread & see how close I was to finished. I needed a few more thou, so back at it. Second pass in & I think I missed disengagement of the half nut.
Of course loud noise, I jumped back (involuntary reactions suck), instead of instantly smashing the e-stop. As quick as I could I hit the e-stop, but of course this is way too late.
So I take the nut off the top of the tool post, remove the bolts for the cross slide & get my tool holder out of the chuck jaws.
Re-installed the cross slide & mounted the tool post back up…,…,…time to see what the consequences of my mistake are.
I start the lathe back up, engage half nuts in the same gear I was already in (C-1). Everything runs but the gear makes a noise, maybe like a damaged tooth.
I stop the lathe, looking up inside of the gear box & I really don’t see anything.
I tried some other gears real quick & all other gears sound normal. Go back to C-1 & the noise is there, as expected.
I’m still kind of in shock/shook up that I’ve just crashed my new lathe. As a matter of fact, after it happened, I said out loud “Oh my god I just crashed my lathe!” My thoughts are still a little scattered.
QCGB is coming apart and/or coming out for sure, so I can get a good look at the damage & get it repaired.
Any advice on other stuff to check?
Spindle, bearings, carriage, etc, etc.?.?.?
Of course I’m thinking the worst at the moment. It would be nice if I just messed up a tooth on a gear, but I’m a little doubtful, seeing as how the entire lathe was all locked together to thread when this happened.
Thanks in advance
Randall.
