Thanks! Great information. As an advanced novice worker, I finally decided to build my first bench a couple years ago. After reading several of your blogs knowing full well mortised dove tale leg joinery is yet beyond my capability, I elected to build Robert Lang’s “21st Century Workbench”. I also chose his VERITAS Twin Screw Vise in the face vise position. Used an old Craftsman face vise in the tail vise position. Constructed of laminated 9/4 x 31/2″ Pecan and 60″ long because of my small crowed shop. Super happy to this point. As I mature in woodworking I may live to construct one of a different choice at a latter date, but I’m 73 so we’ll see. Thanks again for the advise.
2 - use a plunge router with a bottom bearing cuter bit such as this from rockler: http://www.rockler.com/product.cfm?page=25160&site=ROCKLER .... I thought to use the short one as I plunge it directly downward in the centre of the hole until the bearing reaches within the tabletop hole. I suppose one could use a long one, but the stubbiness seemed more practical (the big bearing ensured accuracy?)
Linseed oil sitting in a bowl, or spread on the surface of wood, is perfectly safe. But a linseed oil soaked rag provides a vastly increase surface area, so the oxidation happens faster, and the rag can provide insulation, trapping the heat. The increased temperature speeds up the oxidation even more, which raises the temperature even more, and the runaway feedback can quickly result in temperatures that will cause the rag to spontaneously burst into flame. This isn't one of those "do not drive car while sunscreen is in place" warnings. This is one of those "keep your finger off the trigger until you have the gun pointed at something you want to shoot" warnings. Rags soaked in linseed oil will catch fire, if you don't handle them properly, and they can do so far more quickly than you might think.
There are a number of tricks to using a router. First, the bit spins in a clockwise direction, as you look down at the router from the top. This means that when you cut with the router from left to right, the bit will tend to pull the router away from you, and when you route from right to left, the router will pull towards you. So, if you're hooking the edge guide along the near side of the board, route from left to right, and when you're hooking it along the far side of the board, route from right to left. Second, always test the position of your bit on scrap material. Your odds of getting it exactly right by eye are nil. Third, don't cut more than 1/4" deep on a single pass. We want a 3/8" deep grove, so make your first pass at 3/16", or thereabouts, and make a second pass to reach the full depth.
AJ and Scott have been very helpful showing me where tools are my first few days there. This is a workshop where you will have to work independently. They will show you how to use certain machines for the first time and orient you to the shop itself but they will not help you with your project. They can, however, be hired to help you with projects if that's what you need. I believe it's $75 an hour and limited to their availability. There is also a host of classes you can take if you want an intro into cabinet making, wood joining, turning etc. There are a lot of different classes that may pique your interests.
The book is well written and easy to read. The illustrations, I'm sure were excellent in 1914 and, are still adequite now. Most of the designs seemed repetitive, though. I wish more attention had been given to lashing materials. If you are looking for that you will find almost none here. The book was fun to read and provided enough inspiration to make my brother and me attempt a large hut.
