Sanding curves is tricky. Sometimes you need a sanding pad that’s both firm and flexible. A small notepad works great. Just wrap sandpaper around the pad and bend the pad to whatever arc you need. Slip the one end of the sandpaper between the pages to help hold it in place on the pad. Give this a try the next time you’re working on a project that has curves and tough to reach spots.
There are many factors to consider when deciding what type of wood to use for a project. One of the most important is the workability of the wood: the way in which it responds when worked by hand or tools, the quality of the grain, and how it responds to adhesives and finishes. When the workability of wood is high, it offers a lower resistance when cutting and has a diminished blunting effect on tools. Highly workable wood is easier to manipulate into desired forms. If the wood grain is straight and even, it will be much easier to create strong and durable glued joints. Additionally, it will help protect the wood from splitting when nailed or screwed. Coarse grains require a lengthy process of filing and rubbing down the grain to produce a smooth result.
With a pencil and a protractor, divide the larger disc into 30-degree wedges to create 12 center lines for the bottle indents. Center and trace the smaller disc on top of the larger disc. Next, with a drill press, drill 3/8-in.-deep holes on the 12 center lines with the 1-7/8-in. Forstner bit, spacing them between the disc’s outer edge and the traced circle. Next, divide the smaller disc into 60-degree wedges and drill six more 3/8-in.-deep holes with the Forstner bit.
