Looks like a free-hand cut on the end to give a reasonably flat surface as a starting point, adjusting the rails on the rest. Is that so?
Currently needing longer rails on my Alaskan, as they are my limiting factor... Trying to decide on a size. Double-ended bars need spur drives, plus another expensive couple of chains, on top of an expensive bar, with eBay having GB, with expensive shipping.
Also, interested in buying a bandsaw mill.
Not being independently wealthy, I'm trying to get by with what I have spent so far.
I'm wondering about the limitations of the Granberg mini-mill/ edger. IF used vertically, I wonder how accurate it is. I have one, never used it. I don't have the the guide rail. Thinking a piece of harder wood cut to size would suffice. Seems like its about 1/2x 1/2" angle-aluminum with holes drilled in it...potentially available locally as raw 'angle'.
I've rolled my big cedar log 90*, so the flat is vertical. Probably a lot to ask with a 32" or 36".
