As a final project in my machinist course I am going to build a belt grinder for knifemaking.

I currently have no idea what features are desirable in knifemakers a belt grinder, other than that it has a motor ( I'm making my knives exclusively by hand filing at the moment:barf: :p ), and would greatly appreciate any direction and assistance I could get.
 
Good luck with the project

These links maybe of some help:

The KMG- This machine was designed with the knife maker in mind. It should give you some ideas.

Deker's build- Interesting read about building a version of the KMG

Homemade grinders- Lot of links and photos

Some other grinder links.

Regards,
Greg
 
Yup, what Ripper said. A couple of things to keep in mind if you go with a KMG-styled grinder:

- The dimensions in my build are a rough guide. Turns out I over-estimated the thickness of a lot of the stock.
- Have some kind of extended arm for leverage on the tracking wheel arm. It makes belt changes less of a PITA.
- Large contact wheels can be had inexpensively from Grizzly and/or Sunray

Either way, show us pics when you're done!

Yeah, Thanks alot guys. This will definitely help. I may do a straight up copy of that one with the detailed bluprints, which are very well drawn. I'll just have to see if I'm allowed to do a project without engineering any of it myself!:o
Although, that sort of thing always seems to happen due to availability/cost of materials anyway!

Are there any sort of blade holding devices one might build, I'm almost picturing a sort of clamp on a crossfeed table. A way that one could "dial" the knife rigidly across the belt, getting a nice crisp line....

You've got those devices attached to the ends of your arms! I'd been thinking about jigs, etc to help my grinds, but I recently visited the shop of a pro maker and got some grinding tips. I've got to keep on it, but I can see that experience will be the best "fixture" of all. Relying on jigs, etc will ultimately waste time and energy on your part. Spend that engineering time practicing your grinding, and try to get a visit with a maker near you after a bit of practice to get some pointers.
