pro-planer knives?

[lyall]

by moving the blade/s the nicks in the three blades are not the some location.
if you only have to move one of the blades. The blade that you moved now removes the material that the other two blades did not remove.
so the board is smooth across just as if all three blade were not nicked.

OH you meant nicked knives. Then I agree.

To make the blades last longer.
Just move one blade to the left or right so the that it moves the material.
You can also move a second blade the opposite the direction of the first blade.
The blades will last a lot longer between sharpens or replacement.

I'd like to hear WHY moving one knife wood make em last longer?

Makes them thar lines what appear after getting a nick in all three blades 'disappear'. Other than that I be curious also!!


One of these days I will learn to get down to the last post before posting myself!!!

I know this is an old thread, but I found something that works well for me on my planer knife alignment tool. I have the flat bar type alignment tool, not the curved one. I know the manual states to scribe a line at 7/16" on the alignment tool face. Maybe it is just my vision degrading, but I find it hard to read this in practice. The problem is that the tool is black set against a black cutterhead with a dark grey knife. Even with a lot of LED light shining in/around, it is still a dark cavity around the cutterhead. My point? There isn't a lot of contrast to see what you are doing to align the planer knife with the scribed line on the alignment tool. My method is to print out a paper ruler and tape it to the alignment knife. Most printers are good enough quality today that you can print a reasonably accurate ruler. Using the link below and making sure your print settings are on the 100% scale, you print the ruler out, then cut it at the 7/16" mark. I have a stereo microscope in my shop (alternative is to use a magnifying glass), so I was able to line up the 7/16" mark fairly precisely with the transition on the tool. I taped it in place. Now, when doing alignment, I just use the ruler "0" line to align my knife to. If you do try this method, make sure you double-check that the printed ruler is accurate with a good ruler from your shop. Using this method, I find the high contrast of the white paper against the dark backdrop of black cutterhead and dark surrounding area helps my eyes to see better for aligning the knife. Anyway, I found this method preferable, so just wanted to share it if anyone else wants to try it.
