white oak harvest

[CptnDon]

Due to Isabella and neglect by the previous owner I am harvesting 2-300 year old oak. The log is 22' by 4 1/2'. The sawmill I found (no easy task!) said they'll have to split the log to fit the saw.

I know that there are different ways to saw a log,
but I don't what they are or what "grains" they produce. Would someone educate me, please.

Thanks in advance.

Not being an expert but being around here long enough I have picked up a few thoughts on this.

Quarter sawn will get your best boards, but flat sawn will get your most boards.

Quarter-sawn is best for boatbuilding wood.

First, the log is cut into 4 quarters. Looking at the log end-on, this is like cutting a pie into 4 equal pieces.

Next, each quarter is set up so that it is cut into boards parallel to a line from the "point" of the pie piece to the center of the outside arc.

This gets you the most boards with the most grain perpendicular to the wide sides of the board.

I can't find a "one square edge" example in Donn's pics, but more economical that pure quartersawn in Donn's example is to halve the log and set it on edge with dogs or blocking in your horizontal bandmill...then sawing thru-and-thru.

Produces boards with good enuf vertical grain that the behavior is quartersawn with out the waste in narrow boards and kerf loss of quartering the log.

That's the way I do it.

Here's a pic of a guitar back cut that way:

These will generally be quartersawn sets with good color matches. If they are not quarter-sawn, they will be about 70% quartersawn, with good figure or some other characteristic to compensate for not being fully quartersawn. We do not cut flitch-matched sets in 3A and lower grades.

To some degree it depends on how you want to use the wood. For boat work quartersawn in certainly the way to go, and quartersawn is also good in terms of producing stable wood. However, IIRC the most spectacular figure with oak is often produced by sawing at an angle to the grain (between quartersawn and flatsawn). This is because of the large "rays" in oak that a quite pretty if they are cut right.

Also, this is unlikely to be an issue with a tree this size, but for trees with a lot of knots you will, I think, get more usable boards with flat-sawing. This is because flat sawing means any given knot runs perpendicular to the face of the board, which is manageable, whereas with quartersawing the knot may run all the way across the board, making the board very weak at that point.

Wow, you guys are fast! Thanks for the input.I'm told we'll have to split(rip) the log to fit the mill so quarter sawing will be almost a given.

The log is going to the mill this coming Tuesday.
I'll let you know the outcome.

Thanks
