We will provide you with a 1-5/8" thick x 5-1/4" wide surfaced (S4S) Red Oak board in the length of your choice. Initally the boards are thicker and wider, and are then dressed on all 4 sides to achieve the final dimensions stated. Keep in mind there may be a slight colour variance between boards.

S4S Lumber

Who are they for? These are ideal for those who aren’t equipped with the necessary tools to flatten and straighten boards.

The term "surfaced" or "dressed" refers to a piece of wood that has been milled. To achieve the necessary dimensions, we select a larger board to work from. Both faces and edges are then surfaced so you can be assured that the board is flat and straight. These boards are available in specific sizes.

For example: 3/4” x 5-1/4” x 24”

Rough Cut Lumber

Who are they for? These are ideal for those who enjoy working with machinery or hand tools to mill their own boards.

We use this term to describe boards that require additional milling. Rough cut lumber have been run through the planer to show the grain however they have not been dressed. You will need to mill both faces and edges. Rough cut lumber are available in specific lengths with varying widths.

For example: 4/4 x (5-6”) x 24”

You will receive a board that is just shy of an inch thick, with a width in the range of 5-6”, and is 24” long.

Quality of lumber is excellent but...

I am glad I found this source for premium quality hardwoods. The Ottawa region had been missing this valuable resource for some time.
The order I placed was not large, as I wanted to evaluate the quality of the product as well as the overall purchase experience.
The order was fulfilled within a reasonable time and delivered in a timely manner but...
After placing the original order I quickly discovered that I had forgotten to add one additional item. I quickly called and mentioned that I needed one additional piece of 3/4 inch X 7 1/4 X 36 piece and could it be planed down to 11/16 inches.
I was told it would be.
However when I received the order this additional piece had not been planed as requested.
Since I do not have a planer I had to resort to using a hastilly constructed router sled which gave acceptable but not the same results as if planed.
Otherwise I am satisfied with the overall purchase and will do so again but next time making sure the instructions are followed.
Thank you for bringing this resource to Ottawa.
Best Regards

Great experience

I have ordered from them on a number of occasions now and have never had a bad experience. Their customer service is excellent and they always take time to explain or right a situation. My go to for Woodworking Supplies!
