* The spring steel sawblade rotates around two aligned wheels, and
passes through a cutting table.
* A few [http://www.youtube.com/watch?v=rwu7G...eature=related
settings need to be correct] to achieve a good clean straight cut
* Woodwork bandsaws can cut unhardened steel, non-ferrous [[metal]]s
and [[plastic]]s, as long as the blade isn't too coarse
* Blades survive [[wood]] embedded with metal, assuming a blade not
too coarse, but won't cut the hardened steel.


==Blades==
* Blades from very coarse eg 3TPI to very fine available.
* Omnidirectional blades and linishing belts also exist.

Blade size:
* A 1/2" bandsaw blade allows straight and curved cuts down to about
6"/150mm radius
* Narrower blades allow tighter curves to be cut, but they are more
vulnerable to breakage & a wandering cut, and have lower max cut rates
for a given TPI, as less force can be put on them.
* 1/8" blades give very tight cuts, but are weak

Teeth:
* Raker teeth are the standard type.
* Skip tooth blades are less prone to clogging, and are popular at low
TPI counts
* Hook tooth blades cut faster
* Spiral blades cut in all directions
* Wavy set teeth are used on very fine blades, eg 32tpi
* Carbide tip blades cut hardened steel, cut everything faster and
stay sharp much longer. But they're not cheap
* Blade bands aren't used for diy

Mo
* For accuracy of cutting, the set of the teeth on a bandsaw blade
should be properly maintained. Once the set has gone, the blade tends
to wander. [[Saw]] settings and blade quality also affect this.
* Blade bands with very coarse teeth can be resharpened several times
in situ with a die grinder. New blades are cheap though.
* Blade storage: fold into 3, and tie or bag.


==3 Wheel bandsaw==
[[image:Bandsaw 3 wheel 5590-5.jpg|right|180px]]

Many small 3 wheel tabletop bandsaws were sold in the 1970s and 80s.
The 3 wheel arrangement gives a small machine the cutting capacity of
a larger one, to an extent. The blade bends too sharply round the 3
relatively small 6" wheels, so the blades eventually snap from
[[metal]] fatigue. These were low end of the market equipment, but
still serviceable once set up right.

They can produce clean straight cuts if set up right. Blades have
shorter life, but are cheap to replace, and such machines are usable
if space for a full size bandsaw is lacking. The 3" cut depth is
limiting.

The blade tends to sit at an angle on these, due to lack of any
provision for the set of the teeth on the tyreless wheels. This needs
resolving for decent performance.


==Other types of bandsaw==
* Metal cutting bandsaws can have a blade cutter & welder to allow
closed cuts, and cutting lubrication system.
* Meat saws have stainless steel blades and a food grade blade
circuit.
* Handheld Bandsaw [http://www.toolbarn.com/product/milwaukee/0729-21/
(picture)], rather pricey as of 2011, used as a handheld metal cutoff
saw, and not normally used for diy
* There are also several very large bandsaw types used in factories
etc
* Portable sawmills are used to process felled trees, and are often
bandsaws. Some are homemade.

Would it be worth including things like tilting tables, a bit on guide
blocks and wheels, setting the fence parallel to the cut track.

Setting blade tension and releasing it when finished for the day.

Part of the process is. The first part, making dimensional lumber out
of the trunk, isn't.

I thought the latter was covered by the youtube link, but I might be
wrong.
With the others, do you want to write something?


Setting blade tension and releasing it when finished for the day.


I've addressed several of these things in an update...


NT

Latest version, addressing several suggestions/questions:


[[image:Bandsaw blade 10tpi 5619-4.jpg|right|35px]]

* The spring steel sawblade rotates around two aligned wheels, and
passes through a cutting table.
* A few [http://www.youtube.com/watch?v=rwu7G...eature=related
settings need to be correct] to achieve a good clean straight cut
* Woodwork bandsaws can cut unhardened steel, non-ferrous [[metal]]s
and [[plastic]]s, as long as the blade isn't too coarse
* Blades survive [[wood]] embedded with metal, assuming a blade not
too coarse, but won't cut the hardened steel.


==Blades==
* Blades from very coarse eg 3TPI to very fine available.
* Omnidirectional sawblades and sanding/linishing belts also exist.

Blade size:
* Wide blades maximise feed rate and blade stability
* Narrower blades allow tighter curves to be cut, but they are more
vulnerable to breakage & a wandering cut, and have lower max cut rates
for a given TPI, as less force can be put on them.
* 1/8" blades give very tight cuts, but are weak

Teeth:
* Raker teeth are the standard type.
* Alternate set blades cut faster, but are a bit more prone to
clogging
* Skip tooth blades are less prone to clogging, and are popular at low
TPI counts
* Hook tooth blades dig in to the wood slighly more and cut faster
* Spiral blades cut in all directions
* Wavy set teeth are used on very fine blades, eg 32tpi
* Carbide tip blades cut hardened steel, cut everything faster and
stay sharp much longer. But they're not cheap
* [http://en.wikipedia.org/wiki/Band_knife Bandknife] blades are used
to cut foam, leather, paper, EVA, Rubber and Carpets. They're not
normally used for diy, and use continuous sharpening.
* Choosing the http://www.allbandsawblades.com/how_to.htm right type
of blade]


Mo
* For accuracy of cutting, the set of the teeth on a bandsaw should be
properly maintained. Once the set has gone, the blade tends to
wander. [[Saw]] settings and blade quality also affect this.
* Saw bands with very coarse teeth can be resharpened several times in
situ with a [[die grinder]]. New blades are cheap though.
* Releasing blade tension after use prolongs blade life
* Saws requiring a key to operate prevent self injury by people unable
to behave themselves - as long as they don't get the key
* Blade storage: fold into 3, and tie or bag. Store in a very dry
place


==3 Wheel bandsaw==

==Other types of bandsaw==

cutting lubrication system. The welder makes sawbands from a large
reel of sawblade, and enables closed cuts to be made.
* Meat saws have stainless steel blades and a food grade blade
circuit.
