I am looking for a Soba 6" rotary table and a chuck adapter plate. Everywhere seem to be out of stock. Does anyone have a secret source or can offer advise on a suitable alternate that is in stock?

I"d look for second hand, sadly there are loads of engineering companies out there selling off top quality equipment at knock down prices. I don"t have a Soba rotary table but their products are, in my opinion at best average. Good luck with your quest though.

If you can afford the Vertex, it is made to a higher standard than Soba. I have a 6" Soba, bought privately, but in new condition, and the first thing I had to do was ditch the central needle roller bearing and turn up an aluminium bush. This was because I noticed a large ammount of radial play when the table was unlocked. I did not think 0.010" movement was reasonable, and who needs a needle roller bearing for the speeds at which a rotary table achieves. Now it works ok. As the table has four tee slots, a four jaw independent with front mounting is easy to fit. I have drilled and tapped holes for a 5" front mount Pratt Burnerd three jaw scroll chuck. This requires some thought, I made the mistake of drilling one of the holes into the drilling for lubrication, and had to re align all three. Now the holes are in the right place, fitting the chuck is easy, and with a test bar in the central Morse taper, and the chuck jaws lightly clamped on it before the screws are tightened, the chuck is centralised to about 0.002" tir which is good enough for my purposes. Having some short grub screws to put in the holes when the chuck is not fitted keeps the muck out of the works.

ps. I note that RDG Tools show a 6" "no brand" 3 tee slot rotary table here Apart from the 3 rather than 4 tee slots, it looks superficially like my Vertex unit.

On the assumption that the graduation lines are of equal width on both machines, an error in rotating the handwheel, of, just for the sake of argument, 1 degree will result in an error of 0.01111111 degrees in the table position.

A sip rotary table used in jig boring will have optical scales, but our scales are good enough for most jobs. The downside of a 90:1 worm ratio is the number of turns required to get anywhere. I prefer not to disengage the worm.

Handwheel markings and Verniers or Division Plates are merely different forms of graduation. What matters in terms of precision is the error, or lack of it, in the position of the Table. So the higher ratio results in less error (greater precision ) in Table position for a given error in the input.
