Dad and I went halfsies on a j200 some time ago after doing lots of inefficient milling with an Alaskan.
And it's been a bunch of trouble. Mostly related to breaking blades. Anyone have one of these to suggest pointers?
How or at what point are your bands breaking (ie comming off the bandwheels? in the cut? out of the cut?).
It's been a while since I used it but it seems like they break in the cut at random and are not being thrown off. I wonder if what's happening is we're compensating for not great alignment with too much blade tension.
How dull are your bands when they break? Running high tension, no lube, and dull bands will cause a lot of heat and stress cracks in the band, which will result in breaking.
We need way more specific info to help you diagnose this problem. There's lots of things that can break blades, from running them dull to a bad band wheel bearing and everything in between.

Get your alignment in order and adjust your tension accordingly. I have seen J200's produce alot of bf of lumber so the lack of band lubrication on the mill is a non issue.
