Pantorouter I call this machine the "pantorouter" because it's essentially a big pantograph mechanism with a router in it. It's used to route shapes from 2x sized templates. I originally designed it for cutting tenons, but the machine is very versatile and can be used for all kinds of wood joints. I invented and published this machine in 2010. In 2014, I built the Pantorouter XL, which is designed to accommodate plunge routers. In 2018, I revised the design, adding a vertically adjustable template holder, moving the depth stops to the side, and a few minor changes to make it easier to build.

The Sagulator - Shelf Sag Calculator The Sagulator helps you design shelves by calculating shelf sag (deflection) given type of shelf material, shelf load, load distribution, dimensions, and method of attachment. You can also specify an edging strip to further stiffen the shelf. See the notes below for usage tips. Notes 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Tips for Managing Shelf Sag If shelf span is reduced by one-fifth, stiffness is roughly doubled (deflection is halved). Credits and References The Sagulator employs established engineering formulas for calculating beam deflection. Special thanks to Steve Stephenson for providing initial formulas and Jeff Bratt for his very helpful input (including the spiffy shelf diagram), and derivation of formulae for handling an edging strip.
In The Woodshop Workbench Design Home Page Kayak Design Software Like many kayak builders before me, having built a few different designs, I began to think about designing one of my own. I was not prepared to pay for a commercial naval architecture package, and I thought it would be a fun project to develop my own kayak design software. KayakFoundry is the result. Version 1.6 is now available for download below. This is a free program, but contributions are welcome! Download: KayakFoundry 1.6.4 (November 14, 2009) KayakFoundry 1.6 Features: Stability Curves Multiple views for shaping the kayak in Plan, Profile, and Body Supports 1, 2, or 3 cockpits with independent or shared shapes Auto-positioned cockpit tracks with changes to center of buoyancy Resizable/hideable panels Waterlines and buttock lines Active Section view shows all section dimensions Curve shaping by dragging control points Rubber-banding for multiple control point selection Keyboard arrow keys provide fine adjustments of control point position.

Headlines | Norse Woodsmith The Iron Hand - Emmert Vises Born in the mind of Joseph F. Emmert in the 1880's, the Emmert patternmaker's vise has become world renowned. Patternmakers, woodworkers and machinists would agree that this Emmert invention is the most versatile work holding device available. The Emmert patternmakers vise has the unique ability to not only hold the work piece but to change positions without releasing it. Joseph Emmert lived in Waynesboro, PA and started the Emmert Manufacturing Co. Tabouret en bois Un tabouret de bois massif, à décliner dans toutes les tailles, selon les destinations qu’on lui réserve : sellettes, supports pour plantes, petit bout de canapé, tabouret pour enfant. Avec des planches de chantier récupérées, on peut fabriquer ces petits tabourets robustes et polyvalents. Matériel : - 1 planche de chantier 2 m x 25 cm x 27 mm - scie et ponceuse - perceuse-visseuse ou chignole - 1 mèche à bois et des tourillons - colle à bois Selon la taille de tabouret, débiter :Grand tabouret : Plateau : 25 x 25 cm (1 x) Pieds : 18 x 16 cm (2 x) Traverses : 15 x 5 cm (2 x)Petit tabouret : Plateau : 22 x 22 cm (1 x) Pieds : 16 x 15 cm (2 x) Traverses : 12 x 5 cm (2 x) Assembler les éléments avec la technique du chevillé-collé : Après avoir percé des trous avec une mèche à bois – le diamètre de la mèche doit correspondre au diamètre des chevilles de bois. Déposer un peu de colle dans chaque trou puis insérer une cheville.
Restoring a Stanley No 7 Jointer Plane Every time I see an article in a woodworking magazine about restoring an old plane, it's usually a Stanley No 4 smooth plane. While a smooth plane is probably one of the most important planes to own, it certainly shouldn't be the only plane you have in your arsenal of tools. A jointer plane is extremely handy for jointing the edges of boards straight as well as leveling the tops of wide panels flat. The first thing I do when cleaning a plane is take it completely apart. Next you need to get yourself a product called Evap-O-Rust. Once the parts have soaked overnight, take them out and wash them under the tap to remove any residue from the part. Now that the plane is clean, you'll need to make it work. Next and most importantly, you need to sharpen the blade. Now it's time to see the results of your work. With about an hours worth of work, you can a have a perfectly usable plane and save hundreds of dollars as opposed to going out and buying a brand new plane off the shelf.
