how to make very big cone on the cheap

check out my L3 build thread . so how its done take a traffic cone close to the dia of your build and glass the inside with one layer . let it get to the green stat and pull it out . no need for release or wax . it will not stick . just make sure you compress the inside balloon ,trash bag . after its pulled out place it on it form . after it cured you can put the coupler in and put a section of the air frame to get your length and shape right . make sure you peel the out side to make room for the glass . for the top put a dowel to make you tip . you can most likely make just about any shape you would need . 3.1 4.1 5.1 can be made by changing the length of the dowel . for me all total if im thinking right for a 10" cone that will be 3 foot tall and weigh less than 9lbs for about $30 . as I go and glass the outside of this cone I will post pictures in the main thread and post here to

the blue thing is a trash can of about same dia and length ( longer than it will be ) to show scale

Wow a lot of views

hmm thats interesting! I may have to try this sometime with some mini cones used for sports and such. They may be perfect for some 4" airframes

Yes with diffent cone you can change the nose cone shape by changing the back ends leghth. 2/3 to 1/3 . For this one . Just play with the ideas .hobby lobby 6" paper macha Easter egg and 4" air frame will make a big bertha type cone

9 lbs for the nose cone ? Does that include the airframe section and coupler ? Its hard to tell from my phone and the little picture , but are you using matt glass and polyester resin ?

Eric yes 9lbs nose cone and coupler . And yes it was polyester resin . This was the first layer (inside of cone )
