The trouble in building a pyramid

match the spiral curve as they roll it up. That could be a serious
alternative to the straight ramp idea, which seems to me to be

reproducably for hundreds of logs.

The tapered logs would roll in a circle with a fixed radius (dependant on the severity of the taper). Maybe I'm picturing it wrong but I always pictured the spiral ramps as basically a pyramid with the ramp running round the outside (you can't have paths above other paths). If that is how they are then the tapering would have to change as it went up the ramp.
