This is where you have to be very careful cutting through the VERY thin inner sleeve, "shell" as it is referred to in the instructions. Using a hand hacksaw, as recommended in the instructions,  cut through the sleeve. You may consider making an additional cut opposite of the first to allow easier removal of the sleeve. If you choose to use a reciprocating power tool, as I did, allow only a maximum of 10 recipts with light pressure. It is very easy to cut through and mar the housing.

Do NOT use a square chisel as seen here. Marring of the housing will occur. Use a round punch, as seen in the tools above.
