Thanks for stopping by but I don’t spend six months developing, prototyping, testing and producing plans with the intention of giving them away.
I do however have plans in development that will be for sale as soon as I finish writting the instructions for them. At a mere $20 for hard a copy it’s extremely cheap. You see I do this for a living and $0:00/hour is just a little bit less than I can live on.
And no you will not be able to get them as downloadable files because I want to delay how long it will take for someone to pirate them and profit off my work. I’m really quite a prick like that, expecting to profit off my own work.
The trebuchet plans will be available by October and the ballista should be done in time for Chistmas.
UPDATE: Heres a free trebuchet plan for you. Read the post carefully.
UPDATE: Go here if you’re looking for a large ballista plan and want to answer some questions on the subject. Below are the links to the two files to build your own rubber band powered table top ballista. At present the free ballista plan has had well over 1,000 downloads and the donate button has been used a total of zero times. So, you’re welcome, but give some thought to actually flicking me a couple of bucks once in a while because I’m feeling not particulaly inspired to keep working for free.
