Chris the original 3C adapter when seated in the spindle taper was flush to the end of the spindle.? Most 3 MT adapters today that will fit your lathe have a shoulder that sits outside of the spindle.? This means that the draw tub must be longer by the difference in the new style nose adapters and the original Daltons models.?? Now not all is lost because the shoulder on the draw tube that buts up against the end of the spindle can be machine back to make the tube longer so the original draw tubes will work with the new style of nose piece.? Will see what I have for pictures Chris.? OK Chris the first picture is what the original looks like the second picture shows what the modern SB style of nose piece looks like.? Either one will work. ?You guys may note in the first picture the thread protector is an original Dalton and also notice that this lathe being a very late model Lot 5 has bronze bearings not Babbitt. Also I have a second thread protector that has straight knurls like the ones I made this one shown has diamond knurls.? ?Dennis.

I looking at setting up my Chinese mini lathe up for collets after I get the new spindle bearings in and I figure I should try to find a setup that will also work with the Dalton if possible.

Went through a lot of old threads, but I'm still unclear about using collets in the Lot 5 Dalton spindle.

Do the 3C collets fit the spindle as is, or is a MT adapter required?? Would this be a 3MT to 3C adapter like the mini??

Is a collet chuck a better option?

Is 3C the way to go?? I understand I'd need to obtain a drawbar too.
