I agree, that’s a nice and easy set up to start with. I’d say a block plane it’s handy for small areas, and touch ups. A no.5 is excellent but a bit heavy and tiring sometimes. I find that a nice rabbet block plane (shoulder + block) with two irons with different sharpening angles it’s essential to me. One fine flat rasp and a medium flat file would complete my set.
The first step in developing woodworking skills is to be able to discern the best glues, joints (ways of connecting two pieces of wood), and fasteners to use. Whether you need a dovetail joint for a drawer front or a mortise-and-tenon joint for a table leg, Chapter 10 introduces you to the wonderful world of wood joints. With an understanding of the joints in Chapter 10, you can build any furniture project and make it strong and durable.
The very affordable coping saw (often around $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 as long as you have plenty of replacement blades on hand (also very affordable).
