with the catalog blurb about this bit. Since you don't really know a bit until you've tried it, I tried one. It's unlikely I'll ever make a canoe, but the bits are truly useful. Any coopered or staved construction is simplified with this style of bit. There's no need to calculate the angle between adjoining strips in a particular construction. You just rout an adjustable flute-and-bead joint. One edge of each strip is fluted (or coved, if you prefer), and the other gets a matching bead. Put two strips together, edge-to-edge, and you have a tight joint that can be adjusted almost 45° in either direction. Bead-and-Cove Bits Rockier This is a good way to assemble wooden hot tubs, planters, barrels, coopered doors or bowed tops for chests. Usually you see two-bit sets for this application, and in just one size that forms a l/8"-radius flute/bead. While you can mill stock about 1/2" thick with those sets — producing a kind of tongue-and-groove edge joint — the radius limits you to l/4"-thick stock for real staved constructions. Rockler's innovation is to put both the flute and bead profiles on one shank. To switch from one profile to the other, you only have to raise or lower the bit, not change from one bit to another. In addition, four different sizes are available. Lonnie Bird Tambour Door Bit Set: For the first time I can remember, I want to make something with tambour doors. All it's taken to revamp my woodworking desires was about 90 minutes with this nifty three-bit set. Revolutionary, if you ask me. The set originated in the mind of Lonnie Bird, who I know as one of the gurus of reproducing 18th-century American furniture. While I can't picture Queen Anne or Chippendale pieces with tambour, Bird has nonetheless designed a great system. The literature and DVD that accompany the set explain it clearly and provide step-by-step directions for making a tambour-door breadbox. The essence of staved construction is joining narrow slats into curved ^ forms using flute-and-bead joints. The nosed edge of one stave seats tightly into the concave flute of its neighbor. k Lonnie Bird Tambour Door Bit Set Amana Tool X '4 ' I * : Slats created with the Lonnie Bird Tambour Bits have a wood-to-wood connection: the bead along the edge of one slat is captured in the groove of another slat. The singular feature is the interlock of the slats. No need to glue the strips to canvas. Each has an integral bead along one edge and a slot in the other. A slat's bead slides into the slot in its neighbor. Make as many slats as you need, slide them together, and your tambour is done. Making the slats is remarkably easy. Rip l/2"-thick stock into ll5/6M-wide strips. Each strip will yield two tambour slats. Four passes across the shaping bit transform the strip into two ungrooved slats linked at their beads. Rough out each groove with a pass over the table saw 44 Router Bits You've Never Heard Of |
