Graph Guide for grinding ½ mm edges

Guide for grinding ½ mm edges...

Hi all,
I was going through my workshop, cleaning as I went, so that I could post pics of my workshop, and I found this chart...
All self explanatory, but ask questions, and I will answer..

Done, but any chance of a link to a bigger pic, it's blimmin hard to read.

Oh and thanks, this is great. :biggthump

[Stuart Ackerman]

I limit my pic sizes, cause other sites want smaller pics.... I will make the pic bigger and post in first post.

If you want to know grind radius on Chris Reeves knives etc, vernier the secondary profile( the bit behind the edge) and if it is close to ½ mm, then measure the thickness of blade, and then the height of grind, and viola! :)

[Martyn]

Thanks man. :biggthump

[Stuart Ackerman]

I will be converting that chart to a Word document soon.
If anyone wants one to print out and stick up on your workshop wall, PM me with your email address. and I will do a group email from work.

I have just printed the photo, and it looks accurate enough on it's own...

I don't suppose any of you clever folk has a similar guide for flat grind angles do you?

Something that showed blade thickness at the spine, blade width spine to edge (0.5mm) and the angle of the grind (either the angle per side or overall) would be pretty useful to me at least, and it would prevent me from having to mess about with trigonometry, most of which I forgot as soon as I left school.

Is THIS (http://www.brisa.fi/angle1.pdf) what your're looking for Longstrider. It's a guide for grinding Scandi style edges. (Kindly provided by Brisa.fi)

Great stuff. Thanks for that Dai. I have to admit that it doesn't quite do what I need it to for my present project (which is a full flat grind) but it will be damned handy when I make my bushy knife. I'm sure that others will find it useful too.

I'm crap at grinding prefering to rough out with an angle grinder then file, could anyone tell me if they use a jig or hints and tips for free hand grinding.

John...I free hand, but use a rest so that the spine side of the grind is straight.

Thanks for the info

I use a jig for grinding got the idea from Bob Terzuola's book and I noticed Tom anderson also uses a grinding jig.

[Mack1]

Any pics of said "Jig"???:D I know it'd help me alot!:P Bummer about having to close down your site, John!

Thanks all for this useful info...

Apparently Dyson used it to develop the 'airblade'!
