Hi Rick
Also by tipping the material, you are increase the thickness of the cut therefore this is an advantage as more teeth are in contact with the work piece. I know not by much but on thinner materials, this makes a big difference to blade selection. A 2mm thick piece of material angled at 45 degrees increases to 2.83mm across the cutting plane.
If my maths is right cutting 2mm, stock would require a minimum blade of 14TPI to have two teeth in contact but by tipping the work piece, 45 degrees and changing the blade to 18TPI this would increase the cut to three teeth. Which is better for cutting and for the band saw blade. Even 18TPI cutting 2mm stock would still only have two teeth in contact with the work piece.
Please feel free to check my calculations just in case I have it wrong.
Thank you for sharing, definitely worth considering as my guillotine only cuts 1.6mm stock
