Ok everyone got a question here and need advice/help from all the experts here to better understand whats happening here.
I use a Cheapo Mini lathe no name brand variable speed. Now this late uses a # 1 MT and has been great so far. But my issue is with the loud pitch vibration resonating effect that occurrs while turning items that get closer to the tail stock, FYI this vibration only happens when turnining using razor sharp tools. No vibrations and smooth turning at the head but it gets worse and louder the closer I get to the tailstock its almost like a resonating effect that gets bad enough to cause materials to explode off the lathe when turning somewhat sensitive materials. I checked the mandrel and it seems to be slightly off and not PERFECTLY straight hard to see it but it is a bit. It also seems that if I can get egg shaped turnings when I get closer to the bushings not at the head but close to the tail stock (egg shapped is exagerated but using that term as an example.
Now To test I coated one of my old bushings in Dyed ca Glue and ran the lathe mid point on the mandrel and just slightly touched the bushing with a skew to remove some of the CA. Sure enough it removed glue from about 1/2 of the bushing and didnt touch the other side. So could that be whats causing the major vibtrations when turing?
I only have the 1 A mandrel so I can't "test" to see if that's the issue.
Any suggestions would be appreciated. And I am not buying a new lathe yet LOL I know someone will say to do that....
