I have a cooking corner on the porch. It has my grill, smoker, and the griddle cook-top out there. I wanted a kind of old western style sign to help indicate the area. Blacksmithed letters and old wood are the look I was going for. I don’t do much metal work but figured I could cut some basic letters if I had to. I started by 3D printing a B and a Q in the font I wanted. The print only acted as a tracing template, but it help me set the scale of the project and pick the right wood. I started with a jigsaw, but had trouble with the sharp turns I needed.
I tried using a friend’s plasma cutter but got pretty rotten results. Also I am not very good with a plasma cutter as it turns out. I found a cheap nibbler and ended up going that route. The nibbler is a little round punch that oscillates in and out and is powered by your drill. It can start from and edge and cut a swath, or if you drill a starter hole it can do inside curve work. It is hard to get right up to a line, and often you are left with little round cutouts as shown below.
I slowly went through and cut all the pieces out. I was showered in a sea of little crescent shaped metal debris. Those things are sharp as heck! A good magnet sweep is a must for a nibbler. After the roughing pass I used a carbide bit on my dremel to take everything up to the layout lines. The final result was pretty good. Only a few errant nibbler bites were present. To help add authenticity I heated the letters up with a torch to darken them.
After the heat treatment I picked out a piece of cypress and coated everything in boiled linseed oil. The letters got drilled out at points so I could hammer them home with cut nails for the final touches. The firing and oiling got the color of the metal letters about right. As it sits outside on the porch it will continue to age and darken. Overall a pretty nice project once I got the basic metal cutting figured out.
