Re: [CAD_CAM_EDM_DRO] Bridgeport 2J-2 Head Noise

Hi,

I have a clanking sound coming from my Bridgeport clone, it is manufactured
to the same design. It is coming from the back-gear undernieth the front
pulley. It is something I intend to sort out when something breaks or I can
take it out of service for a while.

Regards,

Terry
