I have a RIDGID 6-1/8” jointer #JPO6101 that will need cutterhead knives replaced before too long. I have purchased the new knives but the meager paperwork that came w/ the machine does not address this procedure. I know that I can figure it out, but I am hoping some of you have done this before and can help me out with some tips, instruction, and know-how so that it would be a quick and easy fix. Thanks. bbqKing

Here’s a couple of examples. For the first one you just need a scale.

I bought some magnets (6) and made a fixture like the second example.

The jig looks nice, but I think I would put in the time versus the money. It really isn’t rocket science and it doesn’t need to be done often.

I have a delta JT360 and the cutter head is similar. Their instruction manual is pretty good on this topic.,JT360.pdf

Ridgid has a tool discussion forum somewhere on their site that could be useful.

Although I like their tools, they do have some shortcomings on support issues/supply. Were you able to find the jointer knives at HD? I’ve never seen them there, and usually have to hunt for the planer knives.

I had to order my jointer knives from Ridgid, since HD did not have them. I have not replaced mine yet. I just got these as spares and for the eventual change. If you find some good information, let us know.

I purchased some after-market knives for my Ridgid that are thicker and made of a harder steel. They seem to hold up much better – fewer trips to the sharpening service, and fewer hours spent trying to install them properly. Someday, an 8’ jointer with indexable carbide inserts!
