I'm working on a mechanism to move a drink in and out of a bar bot. I have a mini v linear actuator but I don't want to have the end of the mechanism sticking out of the bar bot all the time. I thought a scissor mechanism could work, but I'm not sure what to use for the joints. I'm thinking of using 20x10mm aluminum U channel for the bars. I could drill holes in the end of each bar and put a mini v bearing in it, but I don't know how to secure the bearing to the bar. There will also be a good bit of torque on the bearings since it has to support the weight of the drink at the end. Any suggestions for the joints? What about how to mount it to the mini v linear actuator cars? Here are a couple of pictures that might make it clearer. https://goo.gl/photos/1Vw6fxJQVXQSTMLc6 https://goo.gl/photos/iTEsemAoiEVpGoNA8 Any suggestions appreciated.
