When you guys make an extended 4-bar how do you connect the joints. Also I do relize you can do it with shafts and collars but I’m trying to avoid using them because it just uses so many of them. So basically I want to know how to connect the joints on an extended 4-bar without collars.
Long bolts through delrin bearings, with a nylock nut done up so that it’s flush but doesn’t cause friction.
We are having a 4 bar arm this year!
