All,
Went to mount my Bernerd 34 4 Jaw to a new backplate today so I could finally get it spinning on the Hercus 260.
The chuck has some cross-head screws that bolt to the faceplate from the front of the chuck (I think its currently its mounted on a backplate for a 9" Hercus). I unscrewed them and looked at the thread - its not metric and I don't have a an imperial tap with the same thread.
The bolts (more accurately screws) look specific to the chuck as they are an excellent fit to the face of the chuck when installed.
Does anyone know what thread they will be so I can get the appropriate tap? They have a tad smaller diameter than M10 with a finer thread. Could they be a 3/8 UNF?
thx
Jon
