Hi Olly.
I used Burmese teak (so-called 'plantation teak') for my RTTL. (6 x 1.5mm) planks laid down using gap-filling Cyno and sealed using four (or was it 5?) coats thinned down eggshell-finish clear polyurethane varnish. I have never used Maple (can't get this where I live ;-) ) but I'm sure it won't be too different from Burmese teak or the Indian teak I used on my many 'dhow' models.
It might be of interest to some here on MBM how I get my 'planks' since we cannot simply pop around to the local hobby shop and buy the stuff. Having cut down large planks of whatever wood I intend using into smaller sizes like 8 x 25mm, I then further reduce these to rough 8 x 2 or 3mm planks using my small table saw. To finish the planks to constant size and thickness I then use the Dremel router table unit fitted with a drum sander, passing each plank through both sides. It's a case of making big pieces of wood into small pieces which I then reassemble into big pieces again. What I still need to perfect is a good use for small mountains of saw- and sanding dust!!!
