G4003G tail stock drill chuck

That's what I did, I shortened my drill chuck arbor so that it ejects just before the ram is fully retracted, ejects just before 0 so I get thefull stroke for drilling. I only did this with my drill chuck as the other accessories ddon't matter.

Not that it matters but I use a 5/8" Bison keyless chuck most of the time & I also have a Jacobs 14N BB chuck on the lathe. I never even used the chucks that came with my lathe & mill. I prefer to use a good quality chuck.


I ended up cutting the arbor down,

Then cleaning it up in the lathe. It was pretty hard stuff
 
I have a Grizzly lathe that takes a mt2 short taper in the tailstock. Regular ones fit, but use up travel. There is a chance you are in the same boat
 
I have a G0750G with the same problem with the chuck MT in the tail stock.
I was looking at cutting it off and was concerned that if I did that, and the taper got stock, I would have to disassemble the tail stock to punch the taper out. The adapter will be too short to use a drift in the ram slot.
After some more looking I decided to put a flat bottomed hole in the end of the taper that would just clear the diameter of the lead screw and leave enough meat and length if I had to use the drift to get it out.
I drilled to 1/2 and then used a 9/16 slot drill to finish the diameter and flatten the bottom. I had to use Mt adapter for the slot drill because I didn't have another chuck.
Worked well. Now the chuck ejects from the ram 0.020" ahead of the zero mark.

This thread is old but I have this same problem with my G4003G that ticked me off the other day. Cobra/Jim, I like that idea. I may do that if I can't figure an easier way to accomplish the same result. :)
