I was in need of a delay tool for a launch and wasn't able to buy one in time so voila. Enjoy.You will need drill bits and some M4 hardware to put it all together.Use at your own risk.To Use:-Motors now come with a 14sec delay and a tool to adjust.-Depending on your motor diameter, you will pick a tool and bit size.-Depending on how much time you want to remove, you will need one or several spacers. Each spacer removes 4sec. Be sure to calibrate.-Assemble tool onto bit and place tool on top of yellow ejection charge hole.-Press bit gently into ejection hole until you feel the solid propellant.-Insert spacers between motor and tool with bit in center.-Move tool down so everything sits flush to motor and tip of bit is still touching propellant.-Tighten tool-You may now remove the spacers and drill into the propellant until the tool sits flush with the motor.-Your motor has now been timed.
