It is a one off. I reckon I could get away with less discs (after a quick recount) I am looking at about 80.
My concern with the bandsaw was getting a "straight" edge across the 75mm as I would have thought the saw would flex. I guess the jig is probably the bit that would help prevent that.
Regarding the chop saw I measured the thickness of our work one and would likely be getting 50% waste on each log as the blade is 3mm too.
Would appreciate any help.
