Build Instructions

There are 6 gears, 4 spider gears in which 2 have studs on their bases, 1 with a hole and a flat base, 1 with a hole and a counter bore, 1 big helical gear with placeholders for 2 spider gears, and 1 helical gear with a hole. there are 3 shafts, the thicker is the input one, the 2 thin ones are the output shafts, and there is one assembly holder. take the spider gear with a flat base and insert it in the counterbore on the bigger side of the case, and take the helical gear with the counter bore and insert it in the smaller side of the case. now take the bigger helical gear and insert it in the bigger side of the assembly, and the helical gear with the hole, insert that in the medium side of the case and pass the input shaft through it and superglue the shaft to the gear if needed. now take smaller output shafts and insert them in the spider gears, super glue if needed. now we are left with 2 gears, take those 2 and align them with the bigger bevel gear and the 2 spider gears and insert accordingly. there is an additional attachment for the output shafts to see the motion.
