Not sure if it would be of use, but I have a catalogue with the various stones/mandrels etc in from when I had mine. It is one of those machines that I very much regret getting rid of. After having to move premises I rarely used it so more or less gave it away…..and of course could of done with its use a 1000 times since!
I`m pretty sure I found the manual on line a while ago, i`ll have a look on my previous computer to see if I can track in down in the favorites list……..
I see there are some for sale on Ebay from an American source, I believe the Sunnen unit is the same as well, I know the tooling is and pretty sure the machines use is the same?
