Hey all

I have a jointer with some really dull blades, and a nick in them – and I dont have time right now to sharpen them… I am working on getting a second set of knives, but dont have the time to have them out of the shop right now.

Im wondering if there are any other options I have to sharpen – I have an in place honing tool for them, but It think these need to be reground…

I have as options

- Belt Sander
- Bench Grinder
- Wet/Dry Sharpening system

Anyone have any advice on how I can get through?

Thanks
A

I use a Makita for the sharpening. If the knives are badly chipped, I’d send ‘em out for the sharpening.

If you can sharpen them in place you will save some grief. Youtube has many videos on it. Here’s 1.

Thanks for the reply guys…

Do you think the sharpening tool is enough to get nicks out?

How deep are the nicks?

You can sharpen them with a jig and some sandpaper of various grits attached to a flat surface. Look up Allen Little (AskWoodMan) on Youtube. He has a video describing how he built his jig.

Or, how about this…. a set of jointer blades is about $15. Look on amazon.

Many jointer manuals describe how to hone the knives in place. It won’t remove the nicks, but will prolong their use. To eliminate the ridges produced by the nicks, you can shift one or more knives slightly to the left or right so they are no longer in line with each other. Here is the honing procedure from an old Boice Crane jointer manual, but the others are pretty much the same (ie: Delta, Powermatic, etc…):

That should keep you going while you wait for a new set of knives to be delivered. With the extra set, you can always have a fresh set ready to go when needed.

Cheers,
Brad

Thanks for the reply…. I have been trying to track down the knife size for my jointer… I just got it used…

Its a general international 80-100 and am trying to find a knife size somewhere to order some new ones!

I have a big project due – so I dont want to spend them out for sharpening right now!

The manual only states it has three 6” solid knives, they are not indexed and the head has jack screws, so pretty much any standard 6” (or even 6-1/8”) knives should work.

Cheers,
Brad
