💡 How does proper mounting impact straight threading results on manual rotators?
Swapping out worn cutters is a handy job when you align the drive pins correctly. Open the side plates and slide the new cutter into place without forcing it.
- Square off the setup so the die runs true against the pipe wall.
- Spin a few passes on scrap stock to confirm even chip removal before hitting the main line.
- Keep the feed rollers slick with light oil to prevent binding on tough steel.
