I have a kit that has long been out of production (Master Scale Mustang...Jim Meister) We want to build a couple, maybe more. It has several vacuformed parts in .040, .030 and three canopies. I talked with the people at House of Balsa since they are near me. Don told me that to pull a canopy over the existing one would distort the original if not supported inside. Making a plaster mold would be posible but he tells me that it will never dry and cause bubbles. How can I go about this. It has a belly pan, upper and lower cowl, canopies, gear doors etc. ,drop tanks, cockpit sides and on and on. I can build a vacufrom machine, no problem but hold can a make plugs...I dont think I can carve them in one lifetime. I don't think the people that bought Meister Scale out when Jim died last year have the molds since they asked me if they could buy the kit. How can I make a suitable plug. Thanks in advance
