Great stuff!
Glad to see you do a dummy run first... Always nice to be certain the templates are correct before attacking nice chunks of tree..
Really nice choices of timbers too, QLD Maple is always a nice timber, especially when you score some quarter cut chunks

One pro tip though, make sure the top timber and body timber are matched for moisture content.
Last thing you need is for the top to be different to body as it can do some funky things as the two timbers balance out... I have seen centre joins open, tops split and also de lamination occour through mis matched timbers.
(You can get a moisture meter for around the $50 mark)
