It may be that they wanted or expected the characteristics of comb grain rather than rift grain. If you bought a door that meets AWI spec then it would be on the door manufacturer. Were they specified AWI? The AWI Specification for rift doors in the manual is not as a percentage but more size and slope. They said some amount of fleck is present in their stock.ĭoors come under a different specification than lumber or veneer. AWI seems to have a standard and I have ordered their book - is that the Wood Institute? In addition, I called Rex Lumber – they have a yard in CT. We need to have a high standard to compete in the market we are in. We have thought a certain amount was inevitable and acceptable but have lacked a reference or standard to back our product and thoughts. They came in with varying amounts of fleck and our client has not accepted the doors because of it. The Quarter-Sawn cut splits the medullary ray of the wood, causing a beautiful plumed or flared appearance referred to as “rays” or “flecks,” often appearing shiny or reflective.The situation that prompted this question is that we contracted out Rift Sawn White Oak doors. All of the boards are thus cut of radial grain, with the growth rings positioned at between 60- and 90-degree angles to the face of the board. Quarter-Sawn White Oak is produced by first quartering the log and then sawing it perpendicular to the growth rings. In addition to the normal Flat cut, White Oak can be cut with a Rift cut, a Quarter cut (or a combination of Rift and Quarter cuts). White Oak trees are naturally knotty, but the wood can be sorted to obtain “Select” grade wood, which is mostly clear of knots. The species stains well, although contact with metal will result in a dark blemish in the wood. The grains of White Oak tend to be longer than Red Oak, which makes the species prized for construction of “Mission” style furniture and woodwork. The hardness of the wood is rated at 1360 (per the Janka hardness test). White Oak is very durable, exhibits high shock resistance and finishes well. White Oak is a dense hardwood with a white to cream to light brown color.
