This photo shows a stick which has been rough cambered. The stick has been planed down considerably from it’s initial size after being selected. I like to remove as much material as possible to relieve stress on the stick during bending. As stated in an earlier post the stick is heated section by section gradually working from one end to the other as the curve or camber is induced. I use a heat gun with a temperature range from 0-1100 degrees. Normally the sticks are rough bent at about 650 degrees. The curve is formed by hand bending the stick over the edge of my bench. The stick needs to remain straight at the same time that the camber is established. An interesting side note to this process is that often the stick will twist from one end to the other as it is bent. This presents no problem though as enough material is left on the stick to facilitate more planing and everything can be brought back into axis.
It is very hard to keep your cool as a bow maker when this happens! Time has been taken to carefully select a stick. Tools have been sharpened for the work. Perhaps an hour or two have been spent planing the rough stick down. Now the maker is bending the stick. In this case I was about 2/3 finished, probably another hour of hard work. Suddenly the stick gives way like butter under the same amount of pressure used on the rest of the stick. This was a beautiful, strong, and resilient stick and now it’s highest use might be as repair material! It cannot be overstated how difficult it is to obtain pernambuco of this quality. It simply isn’t available anymore short of a bow maker’s estate sale. Player’s can acquire bows with wood of this quality but maker’s have great difficulty in replenishing their supply.
In the next post I will fit the ivory tip plate and ebony liner.
