These are from Laser Edge Sales. If you need parts laser cut, I can't recommend Rich Gunderson and his brother highly enough. First they can use almost any file format to cut from so you don't need CAD files. I sent them .pdf files of my CorelDraw drawings and the ribs matched my drawings perfectly. Second their customer support is second to none. I received several emails from Rich keeping me up to speed with the status of my order and when my order came and I was short a couple of the small wing ribs, an email to Rich had them in the mail a day later. Finally I found their prices to be among the best around. Check them out at
