Allen, The only allowance necessary is the 1/4" or so created by inserting the hinge between the two pieces of spruce (see page 88 - Drawing 71 of the KR2 Plans). Keep in mind the down deflection is only 10 degrees, which may not even need the full 1/4" gap. I realize the drawing is not necessarily drawn to scale, but it is materially correct and was a visual I threw together to demonstrate the idea. Certainly, adjustments may be needed to actually install. With that said, I would like to hear from anyone that can test your idea with the solder to understand the weight difference. Thanks.
