Re: Heavy Ten conversion to L00

Bill in OKC too

I've been machining since 1973, with some gaps. Like 35 years, gap. But I'm pretty sure ONE TIME having a chuck spin off would be quite enough. ;)

I'm sort of planning, i.e., lightly thinking about, modifying my existing chucks to have lock screws at 120 degree angles from one another to lock the screw-on chucks in place. I'll need something to let me both angle and drill and index, which so far my shop lacks.

If I were to change a spindle, I think I'd go for the D-series spindle, just because such chucks are easy to find now. Though, if like the OP, I already had chucks of the long-taper type, it would make sense to go there.

YMMV, as they say.

Why would one  waist all the this time to convert. I bean in machining over 50 years never had a chuck come of in reverse. Yes i machined in reverse many times never had a problem. The chuck was installed properly.

Suggest you google ‘L00 lathe spindle nose’ and you will find chart with dimensions and a cross section. The chuck fits onto a male taper, is driven by a key, and there is a locking ring that gets secured on the back of the chuck with a spanner wrench. I think it allows the spindle to be run in reverse without fear of a chuck or faceplate coming loose as is the case with a plain threaded spindle nose.

Could I perhaps ask a really dumb question.

I've got a South Bend Heavy 10L lathe.  Spindle is threaded for the chucks and faceplate.


What's an L00 and why convert?
