2020 2040 extrusion portable band saw guide

quick and basic 2020/2040 guide to butt my portable band saw up to so i can see if itll cut cleaner than my chop saw, might work for hand saw too idk. id use flat nuts to secure it instead of hammerheads, as hammerheads tend to bite and leave marks that make fidgeting around by 1mm or less problematic.
