I’m almost done with my cabinet project and that will be the last thing on the list of to do’s for friends and family. So I’m trying to line up some of the projects that I’ve been wanting to do for me. I’ve got some turning projects to do, knobs and light pulls, etc. Taking a bowl class in April.
One thing I always wanted to do was build a rocking chair. I’ve been looking for a simple pattern, without too many complicated joints, etc. I found one that I think I like and that I can do.
The pattern is in the May 2008 Wood magazine – page 37. Most of the pattern is quite easy to follow and complete. The one LARGE issue for me though is the rockers.
The plan in the magazine comes with a paper pattern for the front, rear and middle portion of the rocker. It tells you to use a trammel to drawer the 49.5 and 52” radius to connect the pattern pieces.
I certainly understand the function of a trammel. But what I don’t fully understand is how to position the trammel to make the curve.
Do you locate the center line of the pattern then put the pivot point of the trammel either 49.5 or 52” from the pattern? I’m sure I could do a lot of trial and error – but thought I’d ask to save some effort.
Thanks in advance.
