Just returned from a trip to t'frozen north, Tynemouth to be exact. Went to
Durham, Beamish (brilliant), Alnwick & Warkworth Castle. At the latter I
bought a working scale model of a trebuchet!

Haven't built it yet, but it will be around 200mm high when finished.
Always been fascinated by trebuchets and the plan is to scale up this model
so I can build one around 1.2m high.

So, is scaling parts up as simple as it seems? For example, one piece in
the kit is 240mm long, if I multiply x 10 it would be 2400mm long - about
right. The cross section is 20mm x 12mm, so that would end up as 200mm x
120mm - hefty timber.

Does it work like that?


Actually it sort of does: however the material you use will go up - in
the model airplane world - from balsa, to spruce, to aluminium as you
progress towards that full size spitfire. ;-)
