Choosing the power source for your portable hone

by Goodson Tools & Supplies For Engine Builders

Portable hones may be driven by a heavy-duty electric drill, air drill or drill press. Optimum RPM is calculated by dividing 1200 by the bore diameter in inches (for example: 1200 / 6 inches = 200 RPM) or by dividing 30,000 by the bore diameter in millimeters (for example 30,000 / 150mm = 200 RPM). If the power source is a drill press or other rigid stroking device, make sure your portable hone is equipped with two universal joints to provide full floating action at the honing head.

by Goodson Tools & Supplies

We’re going to back up a little to something that’s an essential skill to have in engine machining or any kind of machining for that matter.
