As of now, when I machine my own flywheels for various projects, I must also machine a matching collet while the machinery is still set up. This is fine but it is an extra step that I could skip if only I had a reamer of the required angle.
Surely someone here has the knowledge or at the least an industry connection to a manufacturer who could give the info.
Thanks in advance guys.
