Woodworking Techniques and Advice

Profits start to add up with an aggregate

baroneWikipedia 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 cleaning is a cost-saving and critical tool

howard-grivnaBelt 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.



How to avoid those ever-lingering VOCs

john_englishWe’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.”



Value of sliding dovetail construction

The benefits of interlocking, sliding dovetail construction have been well-known for a long time. 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.



Cutting through the noise on air compressors

john_englishThey’re noisy and bulky and a bit intimidating, but air compressors are unbelievably useful in the woodshop. They can be used to run nail- and staple guns, spray finishes, operate pneumatic clamps and jigs, create vacuum seals, even top up the tires on a delivery truck. A single air compressor can provide cheaper, safer and more easily controlled power than a shop full of tools that are equipped with individual electric motors. And, for most woodworkers, using compressed air is as simple as turning on a machine and running a hose.
