I have always wanted to make a liquid fueled rocket but until now I hadn't actually planned on what parts or fuel/oxidizer I was going to use. Sorry for the poor camera quality. The camera I was going to use broke the day before this video was made so I had to use a phone camera. Here are the measurements and parts of the engine in case you are interested
Combustion chamber 1"x8"
Nozzle 3/4"x4"
1" end cap
1" to 3/4" reducer
fuel lines 1/4"x3' soft copper
Brazing rod probably would have been a better idea for attaching the pieces because of its higher heat resistance. Also if the pumps can't deliver the fuel and oxidizer fast enough I will be pressurizing their tanks to force the fuel through the system at higher speeds.
