So I was inadvertently very smart as a teenager, claiming all my dad’s tools that he was replacing/upgrading. One of these was a really old craftsman 149-23871 lathe. So I got this a couple years ago, but have not done anything with it until now. The issue is that it needed just a little help (in surprisingly good shape, really), but it was discontinued a loooong time ago and replacement parts are non-existent. So I took to the internet for technical information. All I could find was this one thread . Now, I thought I hit the jack pot, so I ordered an MT1 live center, as that was what I was primarily lacking.
So here is where things get fun, this particular lathe is not the same as most craftsman lathes. It has no morse taper in either the headstock or the tailstock. The tailstock spindle is a 5/8” fine thread rod with a 1/2” fine thread on the end. There is a slight recess where the stock center would go, but no way can I get a morse taper in that thing. Also, the headstock is just a threaded stud. I have not measured diameter or thread pitch, but will do so.
I have got it up and running by doing some slick stuff, but it requires pictures. So until I can get them, this intro will have to suffice. Stay tuned.
