I get asked alot how i make certain things. So i thought i would do a quick run through of how i made this radar dish Vacuum form pattern. I will list supplies at the end. If i miss anything just ask me. This is an Old school technique, as with model making and patterns theres always more than one way to do it. this is how i did this. its very cost effectve and the pattern will last forever.
I started by getting the basic shape and transferring that to the foam. I used Urethane but pink or blue foam will work for this process too. i cut the shapes out and glued them to my pattern base.
Next i made a sweep, all a sweep is is the reverse of the shape cut out and put on a tube to revolve around the pattern. This is the only thing i dont have a good pic of but i will post a better picture later. i insert a large tube into the center of the pattern that the sweep will telescope into. and that will swing around the pattern. The sweep can be seen at the top of the picture.
Ok so what i did in this picture mix a big batch of bondo. quickly spread it around the pattern and insert the sweep and rotate it around the pattern. make sure to remove excess bondo and stop your sweeping before it starts to harden. This was just the first coat. it took 3 coats to get the surface smoth and ready to primer. Heres a few pics of the additional coats of bondo.
And on the last coat when i was satisfied i was ready for primer i filled the center hole with bondo
