Thank you all for the recommendations. I now have the 4-bolt hold down mod completed. Also, last night I modified the compound. I removed the original post bolt, drilled the base and threaded it (9/16-18) for the LMS QCTP. The improvement is significant, but there was still some movement. This is preventing a good finish. I tracked this down to loose gib screws in both the compound and cross slide. In my opinion the threaded holes for the compound gib screws is too small. I may drill these out for a larger screw/;ock nut.
Another issue I have found is a significant wobble in the spindle three-jaw chuck. Not sure if I am seeing a problem in the chuck or the spindle. Any suggestions would be appreciated.
Thanks,
Frank
