Really liking that Technic lowering mechanism Travis! I was hoping someone would share something like that as I couldn't figure out how to do it...
Here's where I've got to with my ramp. Looks good I think when lowered but not so much when it's raised so i'll keep tweaking. I've removed the original Technic mechanism from the set it so will be interesting to see if I can adapt what Travis has done to make it work.
