4 bar reverse lift

Hello, I was directed here to ask for assistance. If anyone could provide information or some instruction on our team’s first attempt at a reverse 4 bar lift. We are just starting and are having difficulty in constructing this. It has taken us 2 weeks just to create this base. Can someone provide us direction, we have searched the internet for assistance in this task but no luck so far. Thank you for your time.

You just asked this the other day. Don’t use shafts with collars, use standoffs. Look up stuff for help. In general, if you don’t know how something works, don’t try it until you understand it better.
