Animatronic Balsa Wood Hand

Step 5: Hyper extension plates


5. Now that you have the basic joint system you need to put an anti hyper extension plate on top. Use one of the one inch pieces as followed, if one inch does not work go ahead and make it a tad bit longer. Go ahead and place glue on where the black markings would be on your piece of wood be very careful to not be messy. (stray glue could kill the joints movement.) USE PHOTOS AS REFERENCE. Repeat these steps for each finger besides the thumb.
