Not a repair you want to have to do.

My new 170. Ridiculously stiff legs contributing to a catastrophic back failure due to the large amount of leverage on a *very* small piece of metal which connects the upper and lower half of the skeleton. Doll is already being replaced for a production issue; that was bad icing on the cake. Luckily I'm handy with a welder, but I still have to address the root problem, the leg stiffness. I don't want to cut again so first solution will be to use a long syringe to inject vegetable oil into the joint.
