I would have thought that an old musician like you would have used the "tuning fork method".
You can look it up.
When it first came out it didn't make a lot of sense for guys who couldn't hear different notes, but in an age where a tuning checker can be had for twenty bucks it might make sense to tune a bandsaw blade according to the note it makes when plucked.
