I would like to make some aluminum caps for a product I am going to manufacture. I would like to make these caps on my Biesse Rover 4.3 router. My question is about milling the thread on the caps. Has anyone done internal threading on a rover 4.3 router. These caps will have an internal diameter of approximately 2 inches and the thread will be somewhere in the 16 threads per inch range. Thank you for any information or advise with regard to this question. Thanks in advance. John
