I was checking out the 4000, it has a few pluses like QC gearbox and comes with 2 chucks etc. No variable speed is a minus, but a lot of good machinists do without it. What did you have before the 4000?
It's kinda funny when you think about it, The 1001 comes with variable speed spindle but slow to change pulleys for the lead screw. The 4000 comes with QC gearbox but slow to change spindle speeds! I was thinking instead of selling my 7X16 if I keep it I can set one up with a slow speed on the lead screw, probably the 7X16. I haven't changed the belts around yet so if it's slow as molasses I'll keep them both. Actually if all goes well in the future I want a 10K and keep the 1001 for finish cuts and keep the 10K in back gears(Belts). They both have the D1-3 spindle so I could leave the work in the same chuck.
I got my unit heater and all the ceiling insulation in today, so tomorrow I'll spend some more time with the lathe.
