if you run your HLVH with a speed controller instead of a rotary phase converter,you can make it run as slow as you like for face plate work.( The speed controller would be cheaper,too.) You can also make it run faster,but 3000 RPM has proven fast enough for my work. I have not tried using the 1/64" collet! That would be getting down to watch work!
The Monarch 10EE has a much more extended range of threads,and will run to 4000 RPM. However,HLVH lathes always get higher prices. Possibly due to the difficulty of re making the drive mechanism of the Monarch,which is too complicated for most home shop operators. The work envelope LENGTH is about the same,and the EE swings 12". The EE has no heavier a spindle than the HLVH,but many machinists mess up EE's by mounting much heavier pieces of work than the spindle bearings can stand. This even happens at NASA. Too bad as they have several factory rebuilt ones at very high cost. I can't be sure of my memory,but I THINK the EE's cost about $20,000.00 each to rebuild. A machinist friend who works there told me how some of the ham handed "machinists" that they contract work to(though they use the NASA machine shop,have butchered some of the EE's they have there. Some people should NOT be allowed into the presence of fine machinery!! Let alone operate it. I have seen "machinists" use the end of a lathe bed for an anvil!!
