Hi all,
I'm fairly convinced I have a runout problem on my Laguna 1836, and assuming(?) it is a bearing issue, but I realize other causes are possible as well (bent spindle?)
The dial indicator has been ordered and is on its way, but visually, if I thread a chuck on the lathe and turn it on, there is a definite pronounced wobble. If I use a center, I there is a visible vibration in the tip - at least until I turn up to fairly high speed when the vibrations all blend together.
The only thing I can think of that might have caused this was that I recently chucked up a relatively large blank that was a bit out of balance, enough so that the chuck unwound a quarter turn or so each time I turned off the lathe.
I'll plan to call Laguna once I have some actual numbers to report, but I know the expertise on this forum is far higher than what I'm likely to find on the other end of the phone call. I've seen a lot of good information on this site, especially here. I'll post the runout numbers and some pictures here as well once I get them.
A couple of other questions, though -- how big of a deal is it to replace the bearings (or worse, if necessary)? Is there a manual somewhere that explains the process? (It's obviously not in the user guide that came with the lathe.) I'm relatively "mechanically competent" but I don't want to just start removing parts without a plan.
Otherwise, I've been loving the lathe, but something's just not right.
Thanks,
Dan
