Want to build a Tornado 12 from scratch? This full scale and detailed plan is what you need! With purchase, you will get access to download a PDF file (3 downloads.) This plan is representative of how we laser cut our Tornado 12 kit. So, this is a less-expensive alternative than buying the kit and is printable on US (Tabloid) 11x17 and on ISO Standard A3 paper (for our international friends.)
