Many speciality tools are needed to fabricate a kit airplance. I spent years researching the subject and still did not have enough information to get it right the first time. However, my first bulk purchase went to Cleaveland Tools in Ames, IA for their RV10 starter package.
Here is the original packing list. Eric and I did a full inventory on the first shipment, only found one issue needing correction. Some tools were back-ordered, but otherwise responses from Annette from Cleaveland have always been immediate, friendly, and helpful.
This package was slightly under $3000, but I have subsequently gone over that number as the work has progressed. However, I can confirm what every builder already knows – you can never have too many tools!
