[Crw-talk] Sphere Caliper

[wisawdust at charter.net]

I have had several people ask me where I got the sphere and centerline 
calipers I used for part of my demo this last Saturday.  Both were 
developed and are sold by a turner named Soren Berger, from New Zealand. 
The sphere caliper can be found at this link: 
http://sorenberger.co.nz/products/soren-berger-sphere-caliper.  The 
radius/diameter caliper can be found at this link: 
http://sorenberger.co.nz/products/soren-berger-radius-diameter-caliper. 
If you go to Soren's website (http://sorenberger.co.nz), you can also 
see a video he had done on how to use the calipers and turn a sphere.

Also, if anybody is interested, I can make you up set of the sphere 
holders that I had out UHMW.  I would make one end fit a small chuck or 
be threaded directly to your headstock.  For the headstock, I would nee 
to know the thread size or the lathe you are working on.  For the holder 
on the tail stock, I could make up a holder that is threaded, if you 
have a Oneway, Powermatic or Robust live center.  If you don't have one 
of these, I can make one up that fits a standard Delta or Jet live 
center.  The cost would be $20 for a pair of holders.  Just let me know 
if you are interested.
