Started making some cuts even though I don't have the parts yet. I just wanted to get a better feel for how it is going to look. I probably could have done a cleaner job, But I didn't feel the need seeing how it's going to be covered up, anyways.
As you can see, I've got a trackball going in the middle with the SF layouts on either side of it. I may bring the trackball down an inch closer to the edge to give more swinging room and have more room for buttons up the middle. It's not too late. I'll just have to move some support braces on the inside of the CP that would be getting in the way of the TB, but i wouldn't be compromising structural integrity.
Up at the middle across the middle I'll have my administrative buttons. I'm going to have 2 more joysticks up there too. i'll have a 4-way on the left and a top-fire on the right, just inside the red divides. I measured. There's enough room. Oh, and TB buttons will go just above the trackball. With all this stuff going up at the top it might start to get a bit busy even though it does fit so I'll probably bring the TB down.
By the way, all the measurements and cuts you see there were all winged. I used a drafting scale to mark off length intervals, but it's like .8 of an inch thick. Not exactly precise measuring. Then I just traced my joys upside down and used a TB plate to get the right size in the middle. I'll cal it "freestyle construction".

Despite concerns ya'll might have, there is no trouble with a wrist rest. I tried it out and it's fine. I know what some of ya'll are thinking.

Ok I think I said enough for just one picture. I'll let the picture do some talking now...
