I have decided that if I was to build my own cabinets, it would need to be out of natural wood.. I have no way of hauling 4' x 8' sheets of plywood from the lumber yard to my place, so decided that it must be made of natural lumber. After looking at the choices I had, I came down with that I could afford either matched pine boards or shiplap, which is also made of white pine. Shiplap was a bit wider boards, less seams to deal with, so that has become my choice of stock.
Shiplap is normally used on the outside of a house for siding and has a rough side and a smooth side. Both sides are decorative, the rough side is made deliberatively rough, but not splintery like rough sawn wood would be and is relatively free from knots. So, it seemed to be a good choice for materials. As an added benefit, I could get it in either 6' or 8' lengths. The 6 foot lengths would be ideal for making wall and base cabinets. I needed 34.5 inches for base cabinets and 30 inch pieces for the wall cabinets.
Step 1: Know Your Equipment
Other tools needed would be a circular saw, power drill, tape measure, etc.
When I cut boards to the same length I like to setup a stop block, so all the boards cut will be the same length.
Be sure to observe safety precautions when using power tools.
