This is a knex croosbow i built about 1 year back, its not as good as the others on this site but try and give it a go.

Actual Trigger.
Sturdy Handle.
Strong bow (to a good content).

To actually load you have to press the trigger.
The body tends to wobble.

The piece count is rather long so i took pictures for the beginning of most steps.
