On a cheap lathe, like this, steer clear of the gear drives..noisy at best,
nasty finishes at worst. The belt drive will also give you LOWER
speeds..something that beginners tend to overlook in the search for magical top
speeds. That is, until they try their hands at larger pieces and screw
My own Maximat Super II has a gear head..frankly I wish it were a nice quiet,
ripple free belt drive. 90% of all my turning is done at 300 and 600
rev/min..dropping down to 100 rev/min for screw cutting and up to 1100 rev/min
for polishing! Very rarely do I crank it up to top speed of 2200 revs..never
much find the need for all that excitement!
And yes..I DO use carbide insert tooling..just never been fooled into believing
that a SHINY finish is necessarily a GOOD finish!
