    I wouldn’t think size would matter, it can either position or it can’t in my opinion.

    If on a road perhaps itís due to the oil coming off the cars? They probably do rust over then seal themselves off to the air like Corten steel does. Steel railway rails donít rust either when in use,...

    That is the second diagram of a facing head I have studied but both appear to operate the same. The important part as I see it is the differential. The drive comes off the spindle, to the...

    As already mentioned, the problem is likely the screw. If it’s old the part of the thread that gets used is probably stretched differently to the upper part and has pitch error. Or it might be simply...
