Planks with checks (cracks that are on the surface only and do not go clear through the wood) should be watched, as the checks may develop into splits over time. Located just west of Toledo Ohio, we are considered to be in a prime location for all types of reclaimed wood including; hand hewn beams, mantle pieces, reclaimed flooring, and rustic barn siding.

See Victor Chinnery, Oak Furniture: The British Tradition, (Suffolk, Eng.: the Antique Collector’s Club, 1979); New England Begins: The 17th Century, Jonathan F. Fairbanks and Robert F. Trent, Museum of Fine Arts Boston, 1982; and Benno Forman, American Seating Furniture 1630-1730, Norton, 1988. If you can’t find decently treated support posts, make your own by sandwiching three well-treated 2x4s or 2x6s together. Something like a utility pole or a fence post is not much more than a tree stripped of its branches and heavily treated with preservatives; that’s an example of what’s called roundwood. Our reclaimed wood flooring is USA wood only — all original growth from our very own land.

I decided to check out the offerings at the local lumber yard, and found 2″ x 12″ x 12′ and 2″ x 6″ x 12′ fir framing lumber, priced at $19.01 and $8.05 per piece, respectively. The planks should be 1/2 to 1 inch (1 cm to 2 1/2 cm) thick and at least 6 inches (15 cm) wide. I didn’t seal the ends of my lumber but I will definitely weigh the lumber down.


With over 30 years of flooring experience we are proud to offer our reclaimed flooring services. Thicker pieces for dimension lumber are cut next, while the center of the log yields stock for heavy timber pieces. In order to preserve the distinct plank wood aroma, avoid mixing different flavor planks in the same container. When you’re at the hardware store, you can tell lumber has been pressure treated by its green hue and slight dampness. A few years (OK, decades) ago I worked in a furniture shop that made a lot of Oak furniture. In most instances, simply storing project lumber at a targeted humidity level is the best option to ensure it will be at the correct EMC when building time comes.

This might be the best choice for the walnut because there is a considerable premium attached to the wide boards this method produces. Machine stress-rated and machine-evaluated lumber is readily available for end-uses where high strength is critical, such as truss rafters, laminating stock, I-beams and web joints. I’m trying to whittle down the stacks by using the lumber myself for my various projects and restraining myself somewhat from acquiring more logs. However, this is only a guide and can be altered to accommodate longer length lumber. For most woodworkers, running their own kiln to quickly dry lumber may be impractical or excessive.

The planking portion of OSHA’s Scaffolding eTool is intended to address the need for specific and accurate information about arguably the single most critical scaffolding component: The lumber from which platforms are made. For green lumber the dryer should be loaded to its maximum to avoid too rapid drying. We have a limited inventory of crotch and flame/feathered boards, curly oak as well as burl. Hardwood trees take a much longer time to grow to maturity, so the lumber they’re turned into is much more expensive than the softwood variety. The maximum safe-rate” for some hardwoods are presented below for 1-inch lumber.

Solid sawn wood used for scaffold planks should follow the grading rules of a recognized lumber grading association or an independent lumber inspection agency, and be identified by that agency or association’s grade stamp (see examples below). There are three broad classifications of softwood lumber: Yard, Structural, and Shop and Factory. Tongue and groove lumber is designed to fit snuggly together— tongue planks fit into groove planks’ corresponding slots.

Treated or creosote wood has chemical preservatives that are harmful and alter the wood flavor and aroma. If you’re buying treated wood, buy boards that have had time to dry after they’ve been treated. The most common pieces of lumber that you’ll use for projects around the house are two-bys” and 4x4s. The conclusion was that the plastic lumber is a good structural material, but it is not appropriate to simply substitute plastic lumber for wooden lumber pieces of the same dimension in structural applications.
