Saws

Band saws are perhaps our most important tools. Our wood is typically much thicker than the job requires, so it needs to be resawed into planks (it was sawed once when it was cut from the tree). In addition, most of the pieces of a boat are curved, and a band saw is good for curves.

Making thin planks from thick stock is best done with a wide blade, since it will produce a more uniform cut. This saw can take a much wider blade than the one on it now.

These Japanese style hand saws (Noko Giri) are great for making wood joints. Standard American (English) saws cut when pushed, while these saws cut when pulled. The Japanese blade is thus under tension when cutting, and can be thinner than an English saw while producing a superior cut. Traditional Japanese shrines and houses were held together by ingenious interlocking joints between the wood beams. Fine saws are the key for making fine joints.

Some of the saws have course teeth on one side and fine teeth on the other. Others have a stiffening strip on the side opposite the teeth to make the blade even more stiff.

The ship's saw (a type of band saw) on the right is 100 years old. NBBS purchased it from the Almand Brother's yard when they closed, and refurbished it.

Aside from its large size it has unique abilities. The hand wheel in the lower right tilts the curved frame supporting the two drive wheels. Thus, if you need to rip a piece of wood at an angle, you tilt the blade, not the table supporting the wood. That way the wood doesn't slide off the table.

There is a scale of angles on the inside of the throat which makes it possible to change and monitor the tilt of the blade as the cut progresses. With one person feeding the stock and the other changing the blade angle it is possible to make rolling bevels (a bevel that changes along the length of the piece).
