All,
I'm considering some of these fibreglass doors for my 914 track car ... http://www.porsche914fibrglass.com/ seems like a cheap(ish) option for lightweight doors - has anyone used / fitted them before ? |

The build thd: http://www.914world.com/bbs2/index.php?showtopic=244528 A 914 racecar,in Australia,may not be required to have the inner skins at all,halving the weight and effort of fabrication. The shape of the 914's doorskin is a very simple form,essentially an extruded profile,other than the latch detail. A much more crude method may be all that is needed,a one-off,epoxy/glass on styrofoam layup,ez-style. This needs to be intensively surfaced the traditional hand sanding way,filling and resanding to an acceptable smoothness. Simply(ha!)tape the foam into the door opening and cut,surform and sand the foam to the shape 'inside' the rough blocks. A very traditional sculptors approach,think of it as so much easier than working in marble or limestone. Do not cut too deep,go slow and careful,until it 'looks good'.(Like when chiselling tits) The open celled foam will absorb epoxy,so maskoff or paint the areas where the layup needs to be thin. Add a few stiffeners and remove from the car.Gouge out the un-needed foam and layup the backside ribs and formers. Thin,light and stiff door panels is the result,without molds,requiring mucho hand finishing,but ok. After the ease with which the doors were done,begin now on the frunk n trunk lids. Thin,light translucent panels,home-made like the aircraft and surf-boards before them. Keep it clean,diligently vacuuuming and sweeping,wear a mask to keep the foam dust out. Labour intensive,this way is.
