I copied your comments to a good friend who owns a huge moulding factory in Malaysia. 500 + workers and ships container loads of small and medium black mouldings all over the world. Here is his reply below......................

Finger joint is GOOD. It is good in various dimensions – it is good for the environment because with FJ, the usability of wood increased substantially. Wood is natural and it has imperfections from many things, such as knot from a branch and some holes / hollow. With FJ, we cut away the bad parts and still can use majority of the remaining good parts. Trees are not always straight and perfectly rounded so not always we can get long straight boards out of them. Being able to FJ means even short pieces of timber from special parts of the tree can all be used. Apart from the environment, FJ does help with increasing the strength of the moulding, also reducing possibility of twist and bend. In the factory, we test the strength of the finger joints in various stations. Often, when the moulding breaks, it is the part without FJ that breaks, due to reasons such as a crack in the timber, coarse grain or rotten part.
For the framers’ comment, I do not agree that with tiny moulding, there might be a risk of FJ breaking apart if the v-nail happens to hit on the FJ part. This is so because with the number of years we work in this industry, the quantity of FJ mouldings we (and many manufacturers out there) sent and the number of frames made around the globe every day, not once that we hear FJ breaking apart due to a v-nail happen to hit the FJ.
