Like most woodworkers I have more than one router. A good router can be a joy to use and the tasks they can perform in a few minutes can save hours. That all said I am not fond of routers. They are hideously noisy, and make a huge mess. When using a router mistakes happen at 20,000 rpm, which can ruin a pieces of wood in a blink of an eye. Even with my dislike of routers sometimes there is just no getting around the fact that it is the best tool for the job at hand, the picture above illustrates just such a task.
Once I had prepared the board and was ready to start working on the front the first thing I did was make a drawing in pencil directly on the wood. I don't use a grid or any other drawing aids but prefer to draw free hand. I want to reproduce the model as exactly as I can but sometimes things don't 'translate' exactly when enlarging. This was the case with the current project. On the scale model the perimeter border measured 3/4" but when I scaled this up it looked too small. What looked right was a perimeter border of a hair under 7/8". This doesn’t seem like a big deal but it is to me and it is one of the reasons why I prefer to free hand draw the enlarged design, so that it feels right rather than mathematically working out on a grid.
Once the drawing is on the board I covered it with a piece of tracing paper so I could transfer the drawing of the dry creek portion of the design to a piece of 3/4" particle board that is the same size as the headboard. I then cut out the dry creek out of the particle board and clamped it to the headboard. The edge of the cut out area serves as a guide for a bussing attached to the bottom of the router to guide the router in cutting out the dry creek in the head board.
Monterey cypress is not a particularly hard wood but it pulls a lot of silica from the soil it grows in and encapsulates it in the wood. The encapsulated silica in monterey cypress is murder on edged tools and router bits are no exception. I could only remove 1/4" of material during each pass and after 3 passes I had to stop and remove the bit for sharpening. The final pass left a nice clean cut so I didn't need to make a clean up cut of 1/32". I will still need to use a scrapper and/or sandpaper to clean up the bottom. But now I have a flat bottomed dry creek and I can start carving the banks.

* Note: A larger sub base was added to the router to increase the stability while making the cut. Regretabley the picture was taken before the larger sub base was added.
