You know this is going to sound really stupid but.. If everything is good including the gibbs being adjusted right and the table being square and level. check your belts.
Told you it sounded stupid
The face on my parts were not the nice finish they should be.
I had some belts go out. Changed the belts and everything ran fine. after 1-2 days of running I noticed my RPM meter wasnt fluctuating anymore. so just out of curiosity I checked the rpm on the spindle( in the back) it was also steady. it used to run 200-600 RPM fluctuation. Its been ) fluctuation since I replaced the belts.
Like I said It sounds dumb and I am thinking its more coincendce than anything else in my case as I don't think change belts would steady RPMS.
