Well I can't help you at all about being mad enough to commute 40 miles daily on such a contraption Gary (to me, motor bikes are just like nuclear bombs - better if no one had bothered to invent them in the first place!). But that's just me - and I KNOW there are others on this section who will disagree with me - violently probably.
But getting back to scroll sawing, I have had at the back of my mind a pretty complicated Intarsia picture of an aircraft to do for a friend. I haven't even started it yet (been re-wiring and almost completely reorganising my shop in the cellar) but I have had had some PM correspondence with Claymore (Brian) of this parish. He's been VERY helpful and made a number of suggestions that I would never have thought up on my own, including:
1. Imagine the actual object is right in front of you, oriented as per your chosen picture. The bits that are nearest to you are the biggest/thickest bits of your picture, those further away, less thick, those furthest away are the thinnest;
2. For fine detail you can use a wood burning kit (Pyrography) or even a fine soldering iron;
3. If your choice of wood is limited (in colour) then you can use wood colour, dye, or even paint;
4. When setting out the parts, make sure that the grain runs along the longest parts - e.g. for my aeroplane, the grain of the wood will run along the fuselage, and a separate bit, along the wing;
5. If the "nice" wood you've got isn't all that thick you can always raise it up a bit by sticking it onto a bit of ply or something.
As I say, I haven't even started my aeroplane yet but I hope the above will give you some ideas. I'm sure Claymore will be along soon to add (much better) points, and when my aeroplane is finally done (do NOT hold your breath) I'll post some pix.
Hope that helps
