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.
This is the one tool in the shop that provides the greatest opportunity to save money, if you are willing to purchase a well made, light duty machine, and take lighter cuts. In the past I have used General 14" planers that can hog off serious cuts all day long. The problem is that these professional units cost over $5000, and they would crush my buddy as we haul them down the stairs (note: don’t be the guy on the bottom). After doing a fair amount of research, I purchased the Dewalt DW735 13" thickness planer. The unit came with a good manual, and was in a good state of tune. It is light enough for me to carry around the shop without excessive grunting, so that made it very simple to install. The planer has a significant internal fan-assisted chip ejection system. The chips are catapulted out of this planer, so have your dust collector running before you run stock through it. I now have to make more cuts at a lighter cut depth, but I saved about $4500, which makes my budget happy. The planer makes clean cuts, and has two speeds. I don’t see a reason for the two speeds for my type of work, but there is a faster feed rate should you choose to use it. Knife changing is simple and quick.
In general, a table saw requires at least eight feet in front and behind to accommodate standard sheet goods and four feet side to side. A work table should provide four feet clearance on all sides, and pathways between tables, benches and storage units should be three feet wide. Proper clearance will allow you to move about with ease while you work.
If your shop lacks wall space or doesn’t have a long enough wall to accommodate long stock, another option is to place the crosscut saw near an operable doorway with the right-hand side closest to the door (see option 2 in the illustration). This leaves most of the length of the fence to the left of the blade (preferable if you’re right-handed), allowing short and mid-sized parts to be cut to length or trimmed without having to open the door.
Let’s be clear about one thing: No workshop is perfect for everyone. If there were, I could simply give you a precise plan to follow with clear dimensions. Every person who comes to the hobby, avocation, or profession of woodworking has his own particular collection of tools and his own peculiar work style, skills, and desires for the kind of woodworking he wants to do that gives him a unique approach as to how he will lay out a shop: where the tools should go, where lumber and supplies are stored, and how much bench area he needs.
