Can anyone give some goods advices on how to build a transparent canopy with a bubbletop shape, like F-16 or P-51D? Is vacuform the only way to go? I already attempted this technique with some success for plastic model, but i think it's very tedious needing to build a master with correct shape (with plastic models i used the injected canopy itself) and then dealing with irons, heat guns, ovens and so on to melt the plastic sheet. If someone knows simpler and effective ways, please speak. Thank you.
