I’ve got a three other bits of advice: First of all, get really, really good at woodworking. There are lots of people who enjoy it as a hobby. To sell your services, you’ve got to be able to do far superior work or do it much faster than everyone else (preferably both). Failure to do so means competing against hundreds of amateurs who make things for the pleasure of it, then sell their work at cost to fund the hobby. Second, develop great people skills. Most professionals do custom work and few focus on selling a product. Most of them sell a service, and a big part of that is getting customers to enjoy the experience of collaborating with a woodworker to create their dream products. If your customers don’t like you, they can usually save time and money by getting something from an online catalog. People who buy handcrafted items from woodworkers are often attracted to the idea of supporting artisans. The face behind the work is important to them. Last, develop an iron-clad work ethic. In this field you’re directly trading time for money, and that time is very limited. It’s important to be productive, so try to get 40 hours of actual productivity (as in making things) every week. Accounting, phone conversations and social media marketing may be important, but none of them provide an actual paycheck, so they don’t count as productive work.
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.
To minimize potential cupping, we decided to make the top by gluing two pieces of 1×6 together rather than using a solid board. Choose a straight piece of 1×6 with a sharp, clean edge. Cut the pieces long and trim the top to length after you glue the two parts together. For pro tips on gluing boards edge-to-edge, see “Edge Gluing Boards” . Justin and Jackson cut biscuit slots in the sides of the two 1x6s to help hold them in alignment while installing the clamps. Glue and clamp the two 1x6s. Then let the glue set up about 30 minutes before routing the edge (Photo 10).
Thickness planer. A thickness planer is used to fix surfaces of imperfect wood. If you are picking up less than perfect wood from the lumberyard, wood with some surface defects, a planer will let you fix that wood in the quickest time. A thickness planer pays for itself quick as it allows you to buy cheaper wood that doesn’t have perfect surfaces and fix it yourself. Be careful though. You loose wood during planing. So the remaining amount of wood still has to be worth the price you paid for it.
