Lathe vibration in workshop

[BobParticipant @bob17059]

Mass is your friend in this situation. A solid concrete foundation would be the way to go. Assuming you don’t have a maker’s stand weld up a steel bench as heavy as possible and bolt this to the concrete foundation. The bench top could be laminated from 2 x 4 seasoned timbers. Tubal Cain’s book on Workholding in the Lathe should give you some clues on making a bench for your lathe.

Those feet on the bench seem to put pressure on a very little area are they sitting between the floor joists, if so a length of angle either running along the long side front and back to spread the weight or back to front depending on which way the joists run.

As others have said braces for the bench would be a good idea as well as an extra layer for the top.

Suspect the motor.  My brand new Super 7 vibrated like crazy on the high speed range and was very noisy on the low speed.  I replaced the horrible OEM single phase induction motor with a TEC 3-phase and VFD drive and now it’s smooth as silk.
