can anyone tell me what the best type of wood is for making breaker boards?

And if the wood has 'knots' in it, will this make it easier of harder to break?

Parana pine (Very expensive tho), breaks cleanly with no splinters and has a smooth surface.
Sawn timber has a rough finish but is far cheaper and does not break as cleanly !

Stay away from knots if you can, and anything that is damp.

it is easy to add to things already invented.

A knot is denser in mass than the rest of the board. Its presence makes breaking harder. Its presence can also make breaking riskier in that the board does not break cleanly and can cause one's flesh to get caught on the resulting board piece(s). Try it. You will not like it.

A small, fun question for Morning Star:

If you are to break a board which shows even the slightest of a bend in the middle, is it easier to break that board with the bend towards you or away from you?

The wood iv got for my grading next sunday has some knots in it!
not many though and the pieces i'm using have the knots at the top or bottom of the piece-not in the centre.

well i'd have said the logically if you put the board on the 'horse' so you're kicking this part -------------------> ) not this part ------------------>( then it would break easier as it's already bending in the direction which you want it  to break???

having said that,the logical way isn't always the best way!

Iv got my boards in the cupbards under the stairs where it's warm and dry!

Hopefully they'll dry out some more while they're in there! can i bake them in the oven??!! lol

Hi Star,

First, congratulations for passing your 3rd Degree test.
Yes, you are right on the wood direction.

Next fun question: with a board that is not bent, in which direction will it be harder to break; with the rings concentric going away from you, like this )))) or coming at you, like this ((((. This assumes you are to the left of both sets of curved lines.

                                             He conquers who conquers himself.
