The very affordable coping saw (usually under $20) is regularly used for rough cutting shapes in the board, but especially for removing waste from dovetail joints (one of the most common wood joints). An affordable coping saw will work just fine, along with a pack of affordable replacement blades. Read my hand saw buying guide for more detail on brands & features to look for when purchasing a coping saw.
I’m not sold on the need for a power jointer for flattening a surface. That said, I do have a Shopsmith 4″ jointer.. It’s great for jointing edges, and perhaps flattening the occasional rails and stiles, but it of course is inadequate for surfacing wide boards. Would a six inch jointer be better…..not by much. So what do we do? Go to an eight inch, or better yet a ten inch jointer? Now we’re getting into really big, heavy, and electrically hungry machines that are not really suitable for the small shop that is likely to be in a small shed or garage.
I use chisels perhaps more than any other tool in my workshop, so it’s a good idea to not cheap out here. A high quality set of bevel edge bench chisels (new or vintage) will last you many years (likely your entire life) and will be used on nearly every project. I’ve used some descent affordable plastic handle bench chisels, but highly prefer lighter wooden handle chisels with excellent steel.
“Basic,” on the other hand, is a word that allows for growth – and that’s exactly what you want in your woodworking tool kit. You want to be able to take the same kit with you through many years in the craft. With my basic woodworking tools list, I wanted to provide a core set of tools that will serve you well from project to project. I’m especially concerned these days with the transition to hardwood furniture making, as opposed to plywood boxes of various sizes. That’s the transition I’m making right now in my own work!
