lathe's

I prefer and use geared head as belts develop "memory" and can contribute to vibrations. The important thing with machinery is having a regular pre and post use routine and regular maintenance schedule.
Hey Guys,
I use both, types of machine lathe's, belt and gear head.
Both types of machines run smoothly.The belt lathe makes less noise than the gear-head machines. I have been using them for many years and find "NO" vibration within the machines, if taken care of properly.
Keep the belts in adjustment with the proper tention at all times. Align the pulleys up from motor to pulley drives, and on the belt machine, open the top and make sure it's all in alignment. Do this from the get go, and you won't have any vibration.
As the belt wears, just re-tighten. If you tighten the belt and have vibration, something is wrong. Take a look at the spindle bearings, they may have slack, over time, [end play]. They are tapered bearings, with adjustment nuts and locks. Just do not over tighten, and cause them to wear with to much with end pressure. When the lathe is cold, [over night] put your dial-mike on the end of the spindal, and have about .003 run-out, [end play]. When the machine warms up, it will be perfect. If it apears to be loose, tighten up a bit, or if it's to tight, lossen it off a bit. This also applies to gear-head lathe's.
A gear-head lathe makes a bit more noise, you only have a little gear-back-lash when turning on and off.
Either of these machines works very well.
I have two [ belt driven] jet lathe's 13X40, collet chuck lathes, and 3 enco's [ one with gears, 2 with belts],12X36, with 6 jaws adjust-a-chuck .
Maintance,
All machinery needs to be maintained properly.Clean and oil it, every day it's used. You take care of it, it will take care of you.
In oiling the bed ways, never use a heavy bed way oil. Use, automobile-transmission oil, [the red stuff], saw/dust won't stick to it, just floats off. With heavy oil, saw/dust piles up and becomes hard to move the carriage, and other working parts.
