I'm quite a bit late in this thread, but I've been watching
it for a few months now. I have some stuff which might be of interest.
Here is a Sig Ariadne that I did some revision on. Extra holes in the air bearing and some cleanup of the casting helped. A rework of the air distribution and inline regulator and filters as well as a gauge and an air switch.
Yes, I feel the original air bearing linear arm is a relatively poor design and I needed a piece in the air bearing whcih I could not reproduce. So out went the air
linear arm and in went a unipivot (I'm sure a few purists will be gesticuluating and sobbing, but it really made it
a better table). I may consider going to a modern air bearing arm at some point, but I'm currently happy with the results.
The pics are a few years old, many changes in TT stand etc. have been made. The dehydrator and air regulators and dryers have been retained, but I decided to run the
air from a standing compressor in my garage. Probably the best decision I've made yet with this table. Also now changed is the foot arrangement which now have large knurled spiked pods but retain the original threads into the table, and the left side leveling knob.
With the addition of addional air holes in the platter air bearing, it is easily floated with about 4 psi and not too much air volume. I machined up some extra center pins for the air bearing out of Delrin- if the table isn't exactly level the original will wear out suprisingly quickly.
By the way, replacement Hurst motors are available from Hurst online for about $50.
