I have written previously about making trivets, back in September last year. In the earlier post I described making the trivets. This then is the first in a series of posts that describe and show how I made the trivets. I finally decided in December 2012 to get on with it and finish some trivets before Christmas. Essentially they are a 150 mm wooden disk about 15 mm thick. One side has a series of concentric circles turned on the face to half the depth of the disk. the obverse has a group of three concentric circle turned to a similar depth.
I have made a video of the whole process. However I have broken the video into sections showing the various stages of turning and laying out. The first video shown here details the side with concentric circles. A further two videos shows the remainder of the process.
