I have recently purchased my first lathe, a mk2 Colchester Student.
I cannot feel any play in any of the slides, but there is a tight spot on the cross slide. I am struggling to get a reasonable finish on most materials at the moment but that is mainly down to the blunt inserts and my replacements haven't arrived yet. I have also ordered some hss stock for making my own tooling for turning mild steel.
If i switch the lathe off, or the power feed the tool will dig in to the work piece. It will also dig in if i get to the end of a cut, disengage the power feed and return to the start of the next cut without backing the tool away. This puts a reasonably deep "reverse thread" on the piece.
There is a reasonable amount of backlash on all of the slides and i do compensate for this by over turning the dial and backing off to the desired depth of cut etc.
I have no previous experience of lathes bar a brief spell at college many years ago and occasional use when i worked for a motorcycle restorer, again a long time ago. Is this behaviour usual or is there something i should look for? The chuck is LO taper mount three jaw and runs true.
