Most excellent catapulta you got there, Marcus!
About the bolt lenght issue- I have now bought six metres of 18mm round pine stick which should make a whole bunch of bolts of different lenghts to test. I've got a problem though- my steel tip is too heavy and it makes the bolts poorly balanced, making them to drop faster than they should... has anyone got references on how to make proper steel tips for the bolts? Would the choice of wood used affect the performance of one type of bolt?
