I am delighted to say that I have finished another 1:72 airplane kit. It came out pretty much the way I envisaged it and I did not make any major botch-ups. It will take its place in the collection and be duly photographed. All is well.
No it isn’t.
Scrooge McModeller here has just looked into the empty box and counted the number of extra parts still attached to the sprues – variant parts not needed for the aircraft type that was being built. Of course, they will be preserved for use in future projects, and may be glued onto a motor vehicle, ship, or dinosaur as future occasion demands. But that leaves the question of the sprues. Even if you carefully separate, catalogue, and store the useful bits there is still going to be nearly the weight of the finished model in discard sprues – plastic I paid for that is destined for the waste bin. The Scottish ancestors I do not have would have been aghast, if they had existed…
What can you do with the sprues? They are likely to be of wildly different colours and may even be of markedly different composition – at least it feels like that when you are knifing through the plastic. And they are nearly always awkward shapes and sizes – so they are unlikely to be structural parts for future large-scale pieces.
I did envisage cutting off the side pieces and using the long straight bits for paint mixing stick but found that the effort needed to trim them far outweighed the benefit – and the round-section sprue made a poor job of it in the paint bottles. I gather coffee stirring sticks wherever I go for that purpose.
I should be tempted to melt them down again and press them into a new shape if I knew how to heat them up safely and had moulds that would take them. I suspect that the liquidised polystyrene plastic would still not be very runny and that it would not be possible to just pour it into a mould like plaster or resin.
You understand my desire to reuse the sprues is not ecological concern at all – I regularly hunt dolphins with arsenic bullets now that the unicorns are gone – it is parsimony. I hate wasting something that was paid for. You might say that of the cardboard boxes that the kits come in, but I save these and cut them apart for building material and spray platforms so they get full use.
And frugal ideas from the readership would be greatly appreciated.
