Welcome to A4A Peter.
If you have a considerable amount of wood waste I'd think about making a separate heap just for wood waste because it doesn't break down in the same way as compost, I have a feeling it's quite a different set of fungi that break down wood, in the same way that you'd make leaf mould separately from compost. I think I'm right in saying that compost is broken down mainly by bacteria which work best in a warm heap, but it's wood-eating fungi that you want to work on chippings and shavings, and they need it cool and damp.
