How to Sharpen Planer Blades

This process involves a few simple steps, as discussed below:

Setting the Honing Guide

Place the honing guide on a smooth as well as a flat surface. Place the planer blade into the honing guide and ensure that you hold it securely in a bevel-side.  Adjust until the rest of the bevel connects with the surface.  

The honing guide holds the planer blade at the best angle throughout the sharpening process. If the angle is low, you achieve a sharper blade though less durable. The best angle is 30 degrees, as this will ensure a sharper as well as a durable planer blade.

If you want to use 30 degrees honing guide, then opt for 38 mm of the planer blade.  Set up your setup jig on the honing guide using two pieces of scrap wood through square edges.  Place the two-piece 38mm and use glue to secure them.

Oil the Whetstone

Use a tapping oil to oil your whetstone as this helps to clean the metal.

Get rid of the blade nicks

Get rid of the Nicks if they are appearing on the blade by employing the coarse side of the whetstone.  Move the planer blades across the whetstone and apply some pressure. Make sure that the blades do not move.

Flattening the Back

Flatten as well as polish the back. Start with the coarse grit, medium, and finally, the fine grit.  Do it an inch to the edge while applying enough pressure to the planer blade to maintain it flat.

The coarse grit setting consumes a lot of time while the fine grit setting is quite fast.  Undoubtedly, you are going to end up with a mirror-like planer blade. This is after undertaking all the three grit steps.

Sharpening the Bevel

Use a honing guide as well as a planer blade to rub the bevel on the coarse grit. Cover whole face the bevel and employ a magnifying glass to make follow-ups. Then handle the medium grit.

Repeat the process using a fine grit as well as honing guide. If the planer blade is sharp enough, it will easily cut a thin piece of wood. In the end, you will accomplish a smooth surface.

What angle do you develop planer blades?

A 30-degree angle is ideal for getting a sharp yet lasting Planer blade. Setting the honing guide to 30 degrees needs you to have 38 mm of the Planer blade protruding of the guide. A setup jig for your sharpening guide can be developed by using 2 pieces of scrap wood with square edges.
