And (surprise surprise) weight is an issue, though not as bad as last year. We're at about 107 lb without the ramp release mechanism or dampers or a few smaller things. Hmmm...
Ramps are almost done, meaning they're dampened, hinged, and supported; they just need some stronger springs. We made do with bungee cords tonight (to open up the secondary ramp), and it was pretty sweet. We did note the problem of getting the cable (connected to the ramp frame and the ramp support) caught around the ramp support...
A gripper idea in the works (suction-y), and we have a working design already.
ramp release mechanism
wheels/slides/whatever for end of ramp
finish putting grip tape on second ramp
cross-bracing for tower
(test ramps with paly?)
drill last mounting holes for bumpers
See pictures ;)
