Chopper Arm Support Rig

thingiverse

When building my Chopper, my left and right uprights got swapped and went unnoticed until the frame was glued. This meant the legs would be backwards. Rather than scrap the frame, I came up with this solution. It has held up great for the past year. NOTE - print at high infill - you want this to be solid as it will be supporting your legs on Chopper. 1: Use the Adjustment rigs as a drilling guide to start. You will put bolts through the adjustment rig on to your legs and then use the remaining holes as a drill guide. You are going to be drilling THROUGH your uprights to make room for the new bolts to go through. When it's done you are going to need to clean up and widen the wholes. It will look gnarly. See my photos for an example. 2) Put the rear support in from the inside of Chopper's body. It should fit up against the upright. Use a plastic epoxy liberally here, both on the part touching the inside of Chopper's body as well as on the support rods to the inside of the upright. Every bit helps. 3) Add the front piece to the exterior of the upright. Glue it on with plastic epoxy. You should now be able to put your bolts through from the front piece, through the drilled out upright, and through the back piece. *** NOTE - please don't ask me to share the original upright or leg files - they are not mine to share! ***
