I could write a whole post on wood species as each species has unique characteristics and traits. But, one of the most common types of wood used in DIY projects and furniture building is pine wood (a softwood). Pine is an affordable and readily available option at your local home improvement store and it comes in many sizes. I highly recommend using pine for beginner woodworking projects. Then, as you improve your skill, try working with some different wood species!
My shop ended up being 23 x 19 feet, for a total of 437 square feet. I put my wood rack in the basement, but outside the walled in shop area. To keep the dust in the shop, a three part strategy was employed. I have a dust collection system, an air filtration system and a shop vacuum for cleaning dust out of machinery. I put up new walls, installed new electrical service, lighting, and two access doors for ease of materials movement. The shop includes two windows so that I can enjoy natural light, and not feel like I am squirreled away in the basement.
Great suggestions for a large workshop where there is floor space… the shop I wish I had!!! My shop is a one car garage 23 X 13, which poses a real problem when it comes to workflow and tool positioning. I use your philosophy in reverse Marc; meaning, all my tools are on casters and I store my tools at one end of the shop in an order that allows me to bring the right tool or two into the centre of the shop to use. Bring the tool to the wood.
As the comic George Carlin might say, a shop is mostly just “a place to put your stuff.” The physical aspect of a shop is indeed simply a space of some kind — a garage, a barn, a teepee — that keeps the rain, rust, and robbers away and houses a collection of implements needed to saw, plane, slice, sand, and pound raw wood into useful objects. But just like the difference between a house and a home, what transforms a building full of tools into a comfortable workshop goes beyond the mere physical aspect.
