Hello everyone, like the subject didn't ya? Anyway my question is IRT the
bandsaw. I have been told that a 3/16 in blade should make a fairly tight
turn. Well I have a craftsman 9 in tabletop model and I can't see how to
make a very tight turn. I can't find blades any narrower to fit it either.
This is not the three wheel craftsman, its a two wheeler. I am mainly
looking to do small scroll type work in material 3 to 4 in thick (too big
for my lil scroll saw). Thanks.
Phil

From my G0555 manual:
Blade width Radius of tightest turn
1/8" 1/8"
3/16" 3/8"
1/4" 5/8"
3/8" 1 1/4"
1/2" 2 1/2"
5/8" 3 3/4"
3/4" 5 1/2"

The radius you can cut is limited by the relationship between the
width of the kerf (determined by blade "set" and thickness)and the
width (front to back) of the blade. If your blade cut a path equal to
the blade width (front to back), you could turn 180 degrees in its own
tracks; a zero radius turn. Such a blade wouldn't cut very well in
practical use. It would wander incessantly, twist easily, have too
much set in the teeth and eat your tires, etc. etc. Compromises must
be made, so we have wide blades that track well on fairly straight
lines and narrow blades that are good on the twisties.
The OP is asking too much of his equipment. Tight turns in 3 to 4
inch material isn't a realistic expectation for his saw. He'll have
much better results with 1/4 to 1/2 inch material. A well tuned 14
inch saw with specialized blades might be able to do it.

In general, yes, though of course there are exceptions. I know it's
wishy-washy, but I haven't done an exhaustive study of all the blades
available. I'd expect the extremely narrow blades to cut a narrower
kerf, but at some point, probably about 1/4" blade width, the kerf
stops growing wider. But if you think about it, any blade, whether
it's a bandsaw or a jig saw, can't turn any tighter when the trailing
edge of the blade binds against the side of the kerf.

I think the people that make Timberwolf blades (Suffolk Machinery)
will make a custom length blade for you.

Interesting how with the increase in the size of the blade, the radius of
the tightest turn appears to increase almost geometrically in size Any
reason for this, perhaps blade thickness? I don't own a bandsaw so don't
have any experience in this area.

So if I understand correctly what you're saying, is that the diameter of the
blade set stays pretty uniform in size even though the blade size increases.
