Hello everybody ... Im looking for ideas to plunge mold a landing light lens for wing leading edge. Im gathering up the bits I need to build a 1964 Cessna 172D from the Mini-craft 1/48 kit. I know the kit doesn't have the leading edge landing light, only the single taxi light in the lower front cowling. Would I need to make a male/female or could i use the actual wing as the mold ? How to heat the plastic and what I should look for. Or is it possible to get clear resin or plastic and shape and polish it to get what I need ? if anyone can offer ideas that would be helpful.

This is not a completely new thread. Rob started it back in May and let me tag along adding what I could to help with the conversion. I won’t be reposting all those build photos I posted but will pick up where we left off when the build(s) stalled somewhat when we encountered a problem and hadn’t decided on what to, or whether to, do about it. The thread is here if the subject interests you and you weren’t following to begin with. Quite a bit of scratch building experimentation and Rob’s handy work with aluminium sticky tape. This is the donor kit, Revell’s really very nice Lockheed Ventura. This is the look we were aiming for, or at least what hoped our build would resemble. And This was the problem we encountered. The belly of the Ventura was fairly flat. Rob recons it eas squared off to accommodate the bomb load and no doubt he is correct. He’s leaving his model as is since it is closed up and foiled. Perhaps a modelling nightmare to de-foil and reshape the belly. The belly should look something like this: not completely a semi circle but not too flat either. And this is how, after much mulling over, I’ve decided to deal with the problem. TL: To get the shape I thought I needed a made a template of the top of the nose piece and tacked it to the bottom. Note the “corners” which will be eliminated. TR: that piece was removed and a block of balsa carved to match the shape of the template. BL: male and female moulds were fashioned. BR: a new forward piece as plunged out of .040 styrene. The rest of the belly, right back to the end of the bomb bay opening will be done this way. So, that’s it so far. I welcome any comments, suggestions or criticism. I will no doubt have do a little editing but just wanted to get this posted. Thanks for lookin in. Dennis
