Thanks all, especially Russell for the awesome pattern. It was probably the most challenging piece I have attempted so far. I'm sure others would improve on my efforts but I'm pretty happy with how it turned out. I need to work on hiding my access holes a bit. Maybe spiral blades would help with a pattern like this but I have yet to try them.
@Len, Rimu is native to New Zealand. Here is a link to a wikipeda page about it https://en.wikipedia.org/wiki/Dacrydium_cupressinum. It is very common here although now protected and was also known as red pine. Sapwood is easy to cut but the older heart Rimu can be tough as nails. I have had pieces catch fire from concentrated seams of pitch in the wood when cutting before now. Heartwood can come off the saw with a silky smooth and polished appearance however with no further work needed. It is one of my favourite timbers and I get a lot of it from broken pieces of furniture or old floorboards at the local tip/recycling centre.
