I have made a copy of a wooden part from an old wall wood clock. The original is on the right in the photos. I picked up walnut wood, the biggest diameter is 3.4 cm and the total length is 6.5 cm so it is rather a tiny thing. The stain is dark walnut and even though the copy is a bit darker than the original I think it came out quite well.
As far as wood turning it is important to stay concentrated as one wrong cut and you can start again!
