Re: You provided a good example of peril

Bill, the Tasmanian Oak is my “softer” wood. It is pretty similar to your white oaks. Jarrah is not just a hard wood, but also quite interlocked and brittle. Examples can vary quite widely, nevertheless. I cannot think if something similar from the USA.

In addition to these qualities, one must keep in mind the thickness of the board. I would approach a 3/4” carcase differently from a 3/4” half blind drawer front, and from a 1/4” drawer side. The thicker boards, both hard and soft wood, benefit from a more aggressive toothed saw, such as the LN (about 4 or 5 degrees of rake and 15 tpi). Thinner boards need high tooth counts, such as 18 - 20 tpi, or teeth with relaxed rake, such as the 14 degrees of a Veritas.

How you start a dovetail saw is also a big factor. Particularly so as the rake is towards vertical. What I like about the slim handles of the IT and Gramercy saws is that these force one to hold them lightly. This makes it easier to start the cut.
