When I was a teenager I was building a model every Saturday and soon my bedroom became swamped. I had them on shelves, hanging from the ceiling, and just about every spare spot of spare surface in the room. Then I left home and they all went into carrier bags and were given to neigbouring kids to play with. I kept one large scale motorcycle that I had on display in the model shop window where I worked which I still have to this day. I think over the years you do move on and those models that you know you could have done a lot better will eventually go and you won't miss them too much but those that have a particular place in your heart will remain with you and, even though you can see the huge advancements you have made over the years, you will still enjoy looking at them.
Storage in lexan boxes is a possibility but I think you do have to be rutheless occassionally and get rid of those that you were never very happy with anyway. Fenlanders 190 is a classic example of one that he should always keep because he was so proud of it at the time is was built, and rightly so.
How about a thread on ways in which we have disposed of unwanted models over the years? I have done all of these but don't recommend a number of them as attitudes and health and safety laws are quite different nowadays:
1) Put them in a carrier bag and given them to local kids to play with.
2) Stuck a banger in an
Airfix Bismarck, pushed it out into the pond and watched while the British fleet blew it to bits.
3) Hung an Airfix Lancaster from a washing line and watched the pack of 109's shoot it out of the sky, with the help of an old BSA air rifle.
4) Put a spot of oil on the wheels of an Old Bill Bus model, put some stones in it to give it some momentum and let it go from the top of a steeply inclined pavement. The carnage as the bus crashed into the wall at the bottom of the hill was very satisfying.
5) Tied a 1/72nd Mustang to the bottom of a shilling rocket and watched it take off vertically at a very impressive rate of acceleration.
That's enough from me before I get into trouble!!! I'm sure there are many more methods out there that we remember fondly!
