Title: Wood chipper blades
Post by: J.Z on October 26, 2023, 12:13:33 AM
Hello!
My Name is Jay and a freshly new forum member.
So, I recently bought a Tormek T-8 together with the HTK 806 kit and a used SE 76 jig. My main goal is to sharpen kitchen knifes and chisels.
But there are also some devices that need some treatment.

like my wood chipper. Its a small one that runs on 230V for my garden.
I took out the blades and was wondering how to sharpen those. Is there any jig recommended?

Thanks for your help

I would suggest the KJ-45 if it opens wide enough. I would have though the coarse would be plenty good for these since it is pretty much brute force and ignorance.

They are probably at a 40-45° grind angle, and need a good, clean edge (not razor sharp).  My first thought is that these should be sharpened by hand, running against the Tormek grindstone.

Thank you very much for the quick responses.
I have also considered grinding by hand. It might be possible, as the contact surface of the blade is very wide.

I can't really imagine using the KJ-45 holder. but I will try out both variations at the weekend.

I have a semi-industrial wood chipper and the blades are about 300 (12") x 15 mm (5/8") thick. Not sure how I would do them.  They don't need to be too straight, so long as they are pretty straight and sharpish. My father-in-law threw in bundles of small branches off the ground mixed with gravel and did a nice job on the edge. Last time (BT (Before Tormek))I freehand on a regular bench grinder but it was a job and a half!
