2. Shrox When making your own rockets do you find you never have the right size nose cone to fit the tube Here is a simple little plan by Michel Demey that shows how to build a simple fixture to carve your own nose cones from blocks of EPS ex panded polystyrene foam The advantage is that styrofoam is dirt cheap and it can be found in almost any household Nearly every electronic device is shipped in a oversize foam block for protection which you can now convert into rocket nose cones You can even laminate smaller chunks of the foam together with some light coats of spray adhesive to make really big nose cones Plus this fixture is simple to build and can be made out of the scrap wood you have in your box of rocket supplies Making foam nose cones should cost you nearly zilch to make To make the foam nose cones you ll be carving them to shape with a special fixture and a hot wire foam cutter First we ll describe the special cutting fixture As you can see in the pictures there is a rotating plate and two side templates These will all be made out of wood The side templates have the profile of the nose cone shape We use only 1 2 of the profile so you can start cutting at the same point on the tip every single pass of the hot wire knife That is why there is a straight section extending from the tip of the nose You can use RockSim to print out the nose profile you want and then draw the rest of the template around it on the
