This is a revision to my original model. I have some geometry changes to the bar and change the material to Alum 6061-t6 for a higher yield strength.
I have also included simulation analysis with the assumption of a maximum 50 lbs(22.7kg) of force exerted on handle, and 22lbs(10kg) exerted on hard plastic lever.
Functionality of this tool has not changed. Questions and/or comments are welcomed.
