On the LB10 there are four (5?) bolts holding the headstock in place that need to be loosened.

Below the spindle is a cover plate that allows you to get to two bolts and a eccentric bolt.

Two are under the cover over the spindle.

After they are loosened the headstock will pivot on a pin in the rear of the headstock when you turn the eccentric shaft or bolt in the front. I think an Allen wrench fit in it. It is right in the middle between the two bolts that where under the cover plate. I remember it took me a while to find it.

I chucked up a piece of 2" aluminum and skimmed it. I would check it by measuring and running an tenths indicator along it until I got it turning true. I was lucky that running it along the top showed I had little error. All you can really adjust for with the pivot pin is getting it true along the side.

It took a lot of tightening and and adjusting and re-tightening but it was well worth it having it lined up again.

I imagine your LB15 is similar.
