Tensioning Blades
How much tension should be put on blades? Are there any formulas/rules for this?

Wind it up to max! Have yet to see a bandsaw blade break because it was under too much tension. (I'm speaking of the standard 14" type here.)
If you are concerned about leaving the saw under this tension, back it off when not in use.

Do you think max tension would place a little more strain on the motor at all?
How much wood could the woodchuck chuck if the woodchuck could chuck wood?

Nope, can't because the motor is not attached to the blade.

Some years ago in an article on tuning bandsaws, similar advice was given, together with some figures to show that it's just about impossible to tension a bandsaw enough to break the blade.
One thing worth checking is that the blade is running on the crown of the wheel.

Thanks for the advice. I'll wind up the tension. I was a bit worried about puting too much stress on "me trunnions".
Thanks - Peter

A blade is only as good as the joint ....had to return one of mine to the local sawdoctor after snapping whilst in use with plenty of tension.
