Having not seen one before, I thought I would write this guide to hammer building. It will include the basics of building a WW hammer, from tribe choice right the way through to factors to consider when actually sending it at a WW.
Obviously, hammer building is a personal thing; everyone will have different opinions and preferences, but there are some essentials that are applicable to every hammer builder.
Before You Start
Catapults or rams?
The first thing to do when planning a hammer is to decide what kind of hammer you are making. Whilst you can make a mixed siege hammer, choosing either catapults or rams is much more efficient. Ideally, you want to work together within an alliance to ensure that there are enough of each - a cata hammer without a ram hammer will never do as much damage.
Once you have decided whether you want to build catapults or rams, you can then choose which tribe to be. Obviously, you can build a good hammer using any of the tribes, but each have their own drawbacks.
[INDENT]Extremely wheat-hungry hammers
Most efficient tribe for a ram hammer
Cheapest to train[/INDENT]
[INDENT]Poor as a ram hammer
Poorest off points[/INDENT]
[INDENT]Most expensive to train
Most efficient tribe for a cata hammer
Low wheat upkeep[/INDENT]
Now this is a point that is continually argued about amongst hammer builders; which troops should make up the hammer?
Personally I am of the view that upkeep and training costs should not be a factor in choosing what hammer to build; for a hammer builder, the only resource that is finite is time, and therefore one should pick the troops that yield the highest offence points:training time ratio, which are as follows:
Romans; Imperians and Equites Caesaris
Gauls; Swordsmen and Haeduans
Teutons; Macemen and Teutonic Knights
Of course, there are many different views to this, but these combinations will yield the highest offence power possible for your hammer.
