The Final Stage - (06-22-12: Project COMPLETE. Final pics in OP!)
jkdubb:
Looks good. :) Here is how I would draw large curves.
String and a nail or two to get different arcs.

I always find stuff that emulates the curves I need. Spraypaint cap...CD...wife's shampoo bottle...quarter,dime,nickel,penny...whatever.

Right now I'm hand-drawing the larger curves, but if anyone has a better way to do that PLEASE FEEL FREE to speak up!! I mean, I'll get it the way I want it eventually, but there must be an easier way.

I use a beam compass for large curves. You can make a DIY one pretty simple...
Pencils on a string always mess me up...
1. I have trouble getting an exact radius.
2. The pencil always seems to twist as I'm drawing the curve.
RyoriNoTetsujin:
Thanks for the ideas guys! I may have to build that beam compass just for fun. (Level 3 Super Combo: "COMPASS... BEEEAAAAM!!!")
The smaller curves I'm cool with using either my little compass, or whatever is lying around and fits, it's the larger ones that are a challenge. Thankfully there are only the 3 of those.
As soon as I saw that pencil-on-a-string pic I was reminded that there's a formula for determining the radius of a circle by a chord length and associated arc height. Consequently, I found this kickass website to demonstrate what I'm looking for: http://www.mathopenref.com/arcradius.html
After boring maths:
The lower front arc (down by the base) requires an ~11in. radius... easy enough... :)
The upper back arc (from the top of cab to the back) is a shade above 2 feet radius ... workable... :-\
The upper front arc (starting behind the monitor and intersecting the lower front arc), on the other hand, is from an approximately 5 foot radius circle! :o
The gf says she's got some button thread that doesn't stretch in her kit (she quilts) so she and I are going to mark that out sometime this weekend. Again, with the rain supposedly coming, there may not be opportunity to do much else...
... with the project, I mean. :cheers: :burgerking:
