Woodworking Techniques and Advice
Wednesday, 03 December 2008 14:16In the course of nearly 40 years of furniture making, I’ve made moldings and molded edges in just about every imaginable way. I’ve made them with a shaper and a router. I’ve made them with molding planes and bench planes. I’ve made them with a molding head on my table saw. I’ve even made moldings with the rip blade on that saw by feeding stock diagonally over the blade to produce a cove. I’ve made moldings with scratch stock. I’ve made them with a scraper (rounding an arris to create a radius). I’ve also made moldings by combining two or more of these fabrication methods by, for example, using a bench plane to reshape one side of a cove made on the table saw in order to change that cove into an ogee.
Wikipedia states: “An aggregate is a collection of items that are gathered together to form a total quantity.” OK, I can work with that, although it’s probably not the best description of a tool for our industry. An aggregate or angle head, as the metal working industry calls it, is a device that is attached to the spindle drive of a CNC to allow the user to rout or drill at different angles other than where the spindle is orientated. They are almost always used in conjunction with a tool change format like HSK, ISO or BT.
Belt loading can occur when sanding virtually any wood species, especially if excessive material removal is being attempted, but is especially encountered when sanding soft resinous woods. To minimize belt loading, do not force the cut, keep material removal rates within the recommended maximum parameters for each species being sanded and within the feed speed parameters.
We’re hearing a lot in our industry lately about volatile organic compounds, commonly called VOCs. The Environmental Protection Agency says they “include a variety of chemicals, some of which may have short- and long-term adverse health effects.”

They are self-squaring, self-aligning and self-locking, joining two cabinet components in a way that is very strong and that shouts “quality” to even the most casual viewer. But of even greater value to small- and medium-production shops is the fact that they allow all the components in a piece to be fully finished in the flat before the piece is assembled.
