New 4" Inches (100 mm) Quality Regular Rotary Table for Milling Machines

How can someone attempt to sell something like this its beyond me.

Like someone else commented, I view these type of tools as more or less a kit. This one was no exception. The first thing I did was get out a file and remove all the sharp edges. Then I made a base plate for it so that it would fit on the mini mill nicely. Next up was doing something about the backlash. This type of rotary table has two types of backlash, one that you cannot fix which is the clearance required between the worm and the gear so that it can run. The other is the worm spindle end play. To correct it is a simple procedure, remove the handle/knob and the degree indicator ring. While you have them out smooth out the operating ends of the set screws with some emory paper. Then remove the burrs they left on the shaft when originally installed. If you do not do this the next time you try to remove the knobs and indicator ring you will wish you did. When you reinstall them put the degree indicator ring on and then pull the worm shaft like you were trying to remove it. Slide the indicator ring up against the body of the table and lock down the set screw. This removes the end play on the worm shaft. If you overdo it the table will turn very hard. Then you can put the the knob back on. Once I did this the backlash on mine was extremely small. You should also adjust that degree ring so that it is zeroed when the table is reading zero. That take a bit of fiddling but can be done. Next up was the locking screw. Two problems with it, first it is small, second it is made out of brass. Over tighten it and it will break off easily. I drilled mine out for a 1/4-28 fine thread and tapped it. Then I dropped a small puck of brass in the hole and put in a new 1/4 - 28 threaded knob. 1/4 - 20 will work fine too. Now I can actually lock the table without fear of snapping off the small brass screw. I am not worried if the center hole is running true or not. Probably is but if not I will just rebore it in place on the machine. Doing these things will make it work much better, since they do not do them at the factory is why it is so much cheaper, labor is an added cost, even in India. They do not work for free either.

Good quality for the price, didn't want to pay the earth. I was pleased with the repeatable accuracy and quick delivery.

With the chuck that it comes with it is endless what you can mill with it.

Horrible! Can’t get < 2 degree backlash without making it impossibly tight to turn. Took it apart and found the table is machined off center. Took too long to figure what I thought was me using it incorrectly so now I’m stuck with this paperweight. Grrrrrr! How could they ship this .015 off center — no quality control, that’s how!
