I recently purchased a wedge bed planer (bad shape) and am restoring it, also I’m adding a Shelix cutter head. It has a 5HP/3450 RPM’s motor. I believe the pulleys (2.625 OD / 3.875 OD) are original but not sure. I can get either 5092 RPM’s or 2337 RPM’s on the cutter head. What’s a good cutter head speed? Thanks in advance for any thoughts or comments.

hmm, need more information: What is diameter of cutter head?

The key to machining anything is feed rate. Which for planer is related to both speed and diameter of cutter head.

FWIW – Commercial 15” & 20” Asia made planers typically specify a 5-6K RPM cutter head, and use a ~75mm OD head, with straight cutters protruding ~2 – 2.5mm.

Since you are working with US made Rockwell planer (22-20X?), you should be able to find information to help on http://www.vintagemachinery.org/

Best Luck.
