I just managed to snag one of these 1:1 scale shell replica models for a bargain price, and am working on the seams at the moment, which are a bit of a PITA due to the plastic being ABS or possibly even polypropylene, as it's quite flexible. I'm thinking ahead to painting etc., and had the idea of making it a realistic weight to complete the illusion. I Googled it up and got a figure of between 10.2kg and 10.4kg, so I'm going to go with around 10kg. I also read that the warhead was about 7.4kg, which would make the finished article quite nose heavy, with only around 3kg left for the brass casing, striker and the propellant inside. Am I reading this wrong, or is that about right? I've never handled a real one, so I have no idea, but it seems a bit foolish to me to make a replica that's top-heavy, just in case one of us trips over it and sends it crashing to the ground. I'm also trying to figure out how best to weight it. It crossed my mind to use lead shot, but holding it in place could be tricky, as even epoxy is exothermic and the larger the batch the more heat it generates. I'm also considering plaster, having dug out a couple of kilos of dental plaster I'd forgotten I had during the re-stocking of the workshop after the refit. It's quite compact volumewise, and I could probably give it around 5kg in total, but I'm a little wary as again I'm out of my comfort zone. What other options are there that wouldn't melt the shell or rattle once done?
