Hi,

I lost one of the spindle encoder (the perforated metal plate on the spindle) screws on my Orac, and I can't work out what size it is in order to replace it. The screws are 2.7mm in diameter approximately, but I can't find an obvious match to a non-metric thread size. Can anyone help?

Thanks,
Luke

Hi,

It could be BA?
As some of the screw threads on the machine are BA.
2.7mm could be 6BA

Hope this will help.

HI,

Just checked and on mine it is 6BA.
