Noise in my fairly new Nova Commet 2

[endacoz]

I bought this lathe this fall and have probably put 50+ hours on it. All the sudden at certain speeds I notice this weird noise I have not heard in the past.

I currently have this new noise only at speeds 1300-2000 ish. I have stopped using it waiting to see what I should do before I screw something up.

Thoughts?

checked to see if any set screws have loosened up on the shelves?

Belt is still in alignment??

Shelves? What are you refering to with the word shelves?

How do I tell if the belt is still in alignment?

He means Sheaves - pulleys...

Damn spelling corrections on the tablet!!!!!


Sheaves is now forced into the dictionary.

When I bought mine back at the first of the year the sheaves were out of alignment and it made a knocking noise. I used a straight end to line them back up and have had no problem since and turned a few hundred pens since.

Sheave / Pulley alignment.

If you place a straightedge across the sides of the sheaves, as close to the shaft as possible, and check for gaps at the points where the straightedge contacts the edges of the sheaves, 4 points. If there is an alignment issue there will be at least one gap, possibly two. Hope this helps.
