Hi all,
I have been experiencing some intermittent tightness in the hand wheel operating the cross slide (i.e. when taking facing cuts). Initially I thought that the likely cause would have been a bit of swarf that had worked its way in somewhere so I stripped and cleaned the whole assembly (getting the tapered gibs back in was a lot more difficult that it should have been – still not quite worked out why!) but this intermittent tightness still remains. Adjusting the gibs doesn’t do anything nether does adjusting the backlash nut (as it is I’ve got it set up with a large amount of backlash just now as I figured loosening the adjustment would eliminate any possibility of binding here!).
I’ll be turning the hand wheel in when the resistance suddenly increases. If I back it out and go in again this usually temporarily fixes the issue. I was wondering if anyone else has experienced an issue with this?
I suspect that it may be something to do with the washer / bushing shown in the diagram below as part no 673 (taken from a Grizzly manual however the exploded diagrams are closer to the machine I have than Warco’s own!). I think that this part may be binding so part of me is tempted to take part 607V2 and open it out to accept a thrust bearing but firstly, that part may prove difficult to grip in the lathe and secondly, if I remove this from my lathe then I cannot use it to perform the modification! I would also need to investigate whether there is sufficient material to accept the bearing.
Does anyone have any suggestions?
Thanks,
Sam
