Help close the gap

[twdant]

I've got a component I've been working on, and I'm close to having what I want, but there's still a little work left to do.

The purpose of the component is to be able to scale along the X-axis and retain the 14 degree angle on the rafter. The material also has to remain the same outside diameter, 2 1/4". I've got everything constrained and have formulas that output the correct lengths, but the angle of the joint in the peak changes with the scale. At 20' (measured from outside to outside of triangular pieces on the bottom), the peak joint is correct. Scaling up creates a gap at the bottom of the joint and scaling down creates an overlap. Is there a way to fix it?

Here's a slightly cleaner version:

You will need to use a component with 2 child components - one for the board and the other a small triangle at the end of the board to control the angle.

I thought we had some examples posted but I can't seem to find one at the moment.
