Jack Laister used motorcycle coilover dampers in a couple of his
designs, notably including the LP-15 Nugget. I thought about doing
something similar, but it required more vertical space or more swept
volume than I was willing to sacrifice. The HP-18 gear is an off-the-
shelf solution that has worked well for me in the past, and for which
I have the parts and tooling.
