That's why I don't use the flutter method for tensioning blades. Some
BSers "tune" their blade to acertain musical note. Although I used to
play the violin most of us aren't musically inclined. Instead I use a
similar method but the goal is not listening for a certain note, but
rather listening for a certain "quality" in sound. First, back off the
upper and lower guides. As you turn the tension knob pluck the blade.
At first it's going to make a loose "twang" sound...like a loose
guitar string. Keep turning the knob while plucking till the blade
makes a nice, tight "ping" sound. Loosen and retighten the knob till
you find this transistion (with practice you won't have to do this).
When the blade is making a nice tight ping sound give the tension knob
a 1/4 or 1/2 turn.
Hope this helps,
When I first got my bandsaw I bought Timberwolf blades and spent a lot of
time tensioning using the flutter method. At some point I realized that it
really doesn't need to be that precise. I replaced my spring with the one
from Iturra Designs, started using Lenox blades (bi-metal and carbon steel),
and replaced the crank handle with the one from Highland Hardware. Now I
just crank it to the mark on the saw and forget about it. Sometimes to
check the tension I'll push the blade with my finger to see how much it
deflects. If I turn on the saw and it flutters, then I increase the tension
until it doesn't. In general, I don't worry about it.
I don't have a table saw, so my bandsaw is the primary stationary tool in my
shop. I've never had a blade break. The only times I had tension problems
were before I replaced the spring.
When I first started out, I read all the books on bandsaws and obsessed with
tuning the saw. I used a straightedge to line up the wheels. I put the
dollar bill around the blade when setting the blocks. I spent a bunch of
time setting the tension and adjusting for drift. It might have helped, but
one thing I've learned is that the bandsaw is a pretty simple machine.
There isn't one exactly right configuration that it has to be in to work
properly. As long as the cuts are coming out to your satisfaction, then
there's really no reason to make adjustments.
