On one of the other threads I read last night and this morning, there were questions regarding the "sounds" or "noises" that come from the new G0766.
I began my third project this morning since receiving my unit. [life has just been too busy! I wish I could have done at least a dozen by now! ] This mornings project was the biggest blank I have put on the lathe so far, and probably weighed about 25 lbs to start with and was not balanced, as it had a flat on one side and one end of the blank was bigger than the other end as well.
This G0766 handled that unbalanced blank with such smoothness, that I was impressed all over again! Now my shop building has wooden floors and it is a utility building and the joists underneath that 3/4" plywood are just 2x4's so my setup is far from optimal as far as vibration resonating from anything unbalanced.
As to the sounds coming from the 0766.........I took the time to make sure my air cleaner, and any other machine was off, and I listened carefully to the sounds made during the rough out. What I noticed is what I have stated before........the more I use this machine, the quieter is seems to run.......it was the same with my former G0698. This mornings blank had the most weight so far on this lathe, and while running, there was just the motor fan......[totally enclosed fan cooled- TEFC] and a small hum from the inverter, which I think is totally normal and designed that way.
You may recall, I have had opportunity to turn on a Robust American Beauty that belongs to a friend and have turned to date on 9 different 3520b lathes [some more than once as they are owned by the respective clubs I belong to] and several Jet 1642 evs units. To me.........this G0766 puts off about the same sounds as most of the 3520b's I have turned on.
I think there is a definite break in period with any machine as it settles into its own patterns of wear and also like a car, gets used to the main driver......call it settling or whatever you want, but it is true. What I do know is that my unit is quieter than the first day I got it, and seems to be running smoother as I turn new projects on it.
For those who have just gotten their units, and wonder about the sounds you hear.........give it a little time and I think you will see that the same pattern of settling in occurs and your lathe will likely give you more confidence every time you do a new project!
