harbor freight rotary table manufacturer

The main problem with it, is the double nut that hold the table on/dowm to the base doesnt function properly. It has 3 screws at 120deg that are supposed to lock the nuts but the nuts appear to be machined at the same time so the threads match up perfectly preventing a decent lock and it will back off causing the table to chatter.

I backed off the top nut 120deg and tightened the screw that way so the gap squeezes the nuts togheter. Its better but not perfect as there is no way of getting the bottom nut tight enough to pull the table down with no chatter.

Here is a close-up of one of the two clamps provided. These fit in the t-slots on the rotary table. As can be seen, these are just stamped out metal pieces, screws, and T-nuts.

Most of the Grizzly tables are actually Phase 2 or one of the other better mid grade brands rebadged. I think the 4 inch are Phase 2"s, but either way a 4 in Rotary is a great addition to a mini mill and will be a great fit for the machine in the pic. Sometimes LMS has the 4 and 6 inchers on sale too. Worth a look, but you"ll do well either way with a grizz or an LMS. Don"t forget the dividing plate kit too. Makes it very precise for flanges and other spacing issues.
