Hardwoods, botanically known as angiosperms, are deciduous and shed their leaves annually with temperature changes. Softwoods come from trees botanically known as gymnosperms, which are coniferous, cone-bearing, and stay green year round. Although a general pattern, softwoods are not necessarily always “softer” than hardwoods, and vice versa.
Even if you buy your lumber already planed, you will still encounter many circumstances that require the use of a planer. For example, you might want to build a simple and delicate jewelry box out of small scrap pieces lying around the shop, and you will end up making a small and clunky jewelry box because all of your lumber is 3/4″ thick, and that’s how it is going to stay. That is just the first example. Think about all of the other times that you will pick up a piece of lumber in the shop and it will be the wrong thickness, either just slightly wrong or in an entirely different size category. A planer is a real problem solver and can fix all of that.
In addition to sheer power, look for a model with a built-in thermostat so you can set it and forget it. This convenience feature is well worth it so you don’t have to stop what you’re doing mid-project to manually turn your heater on and off to maintain your desired temp. A good garage heater will mount to the wall or ceiling to save space and will come with a durable housing and full safety screen to keep dust and wood chips from reaching the heating elements and starting a fire.
Temperature and Moisture Control. If your workshop is to be located in a portion of your house that is already comfortably warm, this will not be an issue. But if you’re converting a barn or shed or an unheated space, especially if you live in a climate where winter temperatures make for cold hands, you’ll need to devise a heating strategy. In some climates, air conditioning is a virtual necessity in hot weather.
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.
