Dr Morbius· Open up and say "Aaaaahh"
I agree...I was thinking why doesn't somebody doing the gimble thng use those rotating socket bolts? I see someone has! nice work. Got a vid? I'd love to see it in action!
HA! I knew they existed somewhere..I saw one somewhere before. Thanks TD for posting that...I might also add that you could use two..one for the bottom and one for the top, sandwiched between two nuts (no jokes!! LOL!) on a straight 1/4" threaded rod. No machining needed at all!just a note: if any one needs a Beveled Washer, look here. this would work for the top and they are made of super hard rubber and should work great. I know they make a teflon one to an any size but Ill have to look for it.
just a bit of info that might help some one out they also make Beveled metal grommets too will look for likes
google Cone Washer
