need help with wavy pattern when facing on lathe
I have an Enco lathe that is giving me a weird wavy pattern when I face a piece of bronze bushing stock.
I have tried different spindle speeds, feed speeds and cutters.
It almost seems like the pattern follows the turning of the cross screw, even though I have snugged up the gibbs tight and locked down the compound slide.
I just installed the new tool post, but it seems quite rigid.
Any suggestions as to what is causing this and how to fix it?
Does it have to do anything to do with the bronze material?
Thanks,
Bryan
