Gday all,
A quick sort of question, I hope. I have a Cougar EVS250, which is an absolute cracker of a lathe. Tons of power.
No real issues, but I was turning a large number of spheres for the new family Christmas Tree and noticed a bit of growling coming from the bearings as I held the spheres in place.
I use a fairly simple jig of two chucks, each holding the equivalent of an egg cup. The tailstock one is mounted via a rather interesting doodad sold by Gary Pye (Tailstock Chuck Adaptor). I make it pretty tight to hold the sphere as I rotate it through the three requisite 90-degree machinings. (I love making them, really easy!)
Anyway, it gets away from me..... how long can one expect a set of bearings in the head stock to last? Is it reasonable to assume that they are big meaty thrust style bearings?
Is this something you worry about replacing after a few thousand hours of turning? If they are "groany" after only a short use, is this a cause of complaint/warranty?
