Hi Angel,

       You can buy screw level adjusting bolts with a spherical tip. They 
were referenced on psn in the US, I think last year, but were mild steel and 
fairly expensive. I understood tha they were a 'stock item' in the US.
       You can file / turn your own choice of bolt to a domed end. 
       You can buy cap nuts with a domed head to screw to the bottom of the 
bolt.
       I make a V hole in the end of a SS bolt with a centre drill and stick 
in a SS ball bearing. This rests on a 2" square SS plate glued to the floor.
       If you want a very high turns ratio, Arie had a system using a bolt 
and a threaded rod with slightly differing threads and a central hexagonal brass 
adjusting bar tapped at both ends. These sorts of device have been mentioned 
in past PSN letters. 

       Regards,

       Chris Chapman
