I purchased a wooden Trebuchet kit (in German Blide or Tribok) via Ebay. There was no scale mentioned, so I hoped it would fit to 28mm figures. As I received it (from China), I saw "1:72" between all the chinese letters and I thought, this would be great also for my 28mm crusaders....but no.
I made a quite expensive try with 40mm figures by V&V and even those figures looked like little children while standing near the war machine.
So my salvation was 3d Print. I ordered some 28mm Fantasy Trebuchet crew and asked the shop to print it in a special 50mm scale.....it worked.
So I could go on with a small diorama scene and searching for some fitting stuff (ropes, crates, weapons, barrels and so on.) I did this stuff scratch or by plundering other sets I had in my huge collection.
And then I made a big mistake....I covered the wooden (not MDF) base with my wet basing putty (mixing color sand and wood filler) and pressed the trebuchet in the wet ground. I let it dry over night and in the next morning, everything was in a slight banana shape...and finally i dropped it onto the floor by mistake...so I had to do a lot of work to correct it and make the trebuchet work again....yes it works!!!
It has a 300 g counterweight (using stones and steel balls) and can throw a small stone or hard candy about 7 meters. You can wind it up by using the two "hamster wheels"....a funny thing.
By the way, the "pumpkins" are fire pots....
