Just to set the record straight, the formula linked has nothing to do with anything surrounding the circle (or radius), just the circle itself.  The cut coming into or going out of the desired radius has no effect on the radius itself or the formula used to calculate it, so what was quoted above is incorrect.

Oh, and that's quite an interesting approach you have there Quarters...

Holden,

Are you trying to draw some plans or to plot that curve down for sawing?

As you probably noticed in my plans, I didn't marked the radius of those curves clearly. I didn't because that information was lacking in the pictures/measurements I got from Stuzza at first place. So, after defining some "anchor point" (top of the marquee,  front of the CP and bottom of the cabinet), I just tweaked the curves freely using Illustrator to what I considered more aesthetic pleasing.

As my plans were 1:1, I just used Illustrator to measure the deepth of the side panel at various height point (each 10cm or so). Then I plotted this points on a big piece of paper, used a flexible ruler to smooth the curve out and used it as a template for cutting.

What I'm trying to say is, if you just want to get down to cutting, the template might be an easier way. If you want to draw plans, then God bless you. The world needs some nicely done lowboy plans  ;D. Good luck anyway!

Holden,

Just one more thing. I'm not sure if the curve you posted is taken from my plans or from the lowboy you're using as a model, but... have you considered it might not even be an arc of a circle? The way Illustrator works I'm pretty sure the curves in mine lowboy are an arc of an ellipse or something even more complex...

Hmmm... back to the drawing board, since I still have the original panel I'll try out these suggestions and let you know which worked the best.

Ahofle: That's the answer I needed in my year 10 maths exam, awesome...

hbm*rais: I'll have to take your Illustrator file to work today and take a look. And yes I'm working on some plans for the Lowboy, a bigger mission than I first thought.

I would second the "flexible ruler" idea.
I usually use a long scrap of 1/8" Lexan, put two nails to hold the ends where I want them, and then just pull the center until it "looks right".

The easiest way to actually mark the piece is with a can of spray paint.
The nice thing about this method is that you can hold the Lexan in place, and not have to worry about it moving while you are drawing with a pencil.
