 Our initial impression of the Ryobi P600 was of a product that might contain numerous small components numbering in the 10-20 rage. However, to our surprise the unit dissembled quite tidily into 2 main components - the motor and housing. This led to our conclusion that the router is essentially an electric motor attached to a spinning bit. In addition, judging by the relatively simple demeanor of the unit we guessed that it was composed of around 4 different materials. In reality, eight different materials are represented within the unit.
-The unit can be purchased without a battery as it is a part of Ryobi's "One+" system which is comprised of a suite of tools all of which operate from the same rechargeable battery - which can be purchased separately [Ryobi Limited]. This prevents from purchasing redundant equipment and keeps overall cost down. As such, an operations test could not be performed prior to disassembly. However, an accurate estimation of the tool's operating nature and capacity can be made from the knowledge of routers in general. The rotating bit of a router creates a distinct "whine" which is unique among wood working tools.

		+	As explained previously, operation of this Ryobi hand trimmer centers on the electric motor. The motor utilizes an electromagnetic field created by electricity and magnets to create mechanical energy in the form of a spinning rotor. This rotor turns a wood working bit which is responsible for delivering cutting action along a desired path. The operator can use the transparent base to help guide the router while performing a cut. This unit is also equipped with a depth adjusting device which allows the user to make precise adjustments to ensure accurate cuts. However useful, this device seemed too cumbersome for the small unit and as such we recommend a simpler less bulky mechanism. To our convenience, the unit reassembled in exact reverse order as disassembly had occurred and required only the simplest of tools to maintain: a Phillips head screwdriver and 5/16” wrench. This allowed us to shift our effort and focus on other issues such as engineering design and ergonomics.
		+
		+	Some additional recommendations include integrating the yellow and blue clip-on cover components into a single piece thereby reducing manufacturing costs. We also suggest the addition of more grip/cushioning to the trigger area to allow the user added comfort during periods of extended use. Finally, the addition of a power cord would be would greatly benefit the unit by extending its versatility. We also determined that hand-held power tool prototypes, could be tested in a virtual environment to forecast their performance in real world applications. This would not only aid engineers in technical analysis but dramatically reduce overhead cost for the company.

 In conclusion, we felt several alternatives to the current configuration would result in a more practical design. For instance, the blue and yellow cover pieces of the clip-on cover could have easily been integrated into a single piece and thereby saving the use of four screws. Also, despite the convenience of cordless operation, we felt that the unit would benefit from a power cord option. This would allow the user to avoid time restrictions associated with battery use.

		+	The following steps were taken to disassemble the router:
		+
		+
		+	• First we removed the clip-on cover from the router
		+
		+	• Then four Phillips head screws were removed from the bottom of the wood working sub-base via a Phillips head screwdriver
		+
		+	• Next, the two plastic depth adjustment latches and the attached springs were taken out by hand
		+
		+	• A yellow cap on the top of the unit was removed by hand, thus releasing the strap and the attached clip
		+
		+	• With those parts removed, the blue and yellow casing easily separated from one another
		+
		+	• At this stage, thirteen different components were counted
		+
		+	• Next to be disassembled was the yellow translucent base
		+
		+	• For this, we used a Phillips head screwdriver and the provided 5/16” wrench
		+
		+	• The black painted hex nut was removed first using the wrench
		+
		+	• Then the washer and rectangular spacer slid off by hand
		+
		+	• Finally, the metal clasp was left and this was also able to be removed
		+
		+	• All parts removed thus far were located on the transparent cylindrical section of the unit
		+
		+	• Next we examined the transparent base
		+
		+	• To separate this part from the cylindrical section, we removed four Phillips head screws from the base
		+
		+	• Once this was completed, we had obtaines a fully disassembled router base
		+
		+	• Next in line was the plastic housing which encases the motor and associated hardware, it also gives the router it's distinct shape
		+
		+	• Holding the housing together were eight Phillips head screws
		+
		+	• With the screws out, a simple pinch of the retainer tabs was all that was needed to separate the twin housing components
		+
		+	• Inside we found the heart of the operation: the motor
		+
		+	• For fear of compromising the integrity of the unit, we did not disassemble any further
		+
		+	On a scale from 1 to 5, with 1 being easy and 5 being difficult, all of the disassembly steps rated around a 1. There weren't many moving parts that required extensive disassembly and everything that did break down was of basic design making it easy to disassemble. The only tools used were a Phillips head screw driver, and the provided 5/16" wrench.
