4 bar tightening


Hi, I was thinking of building a 4 bar linkage but I know that they have issues keeping together. I wanna know if there are any suggestions on keeping it all tight. Thanks!


Use bearing flats and 1-2” screws and nylocks for all the joints.


Thank you so much!


No problem. And use nylon spacers or washers, Teflon is best, in between all metal
