Grinding tools, should I make a jig

You will also find that diamond is very harsh when used on HSS, cutting minute grooves rather than the chisel like honed finish you should be trying to achieve with a fine oiled stone.

Ahh, that makes sense. I've got a cheap diamond 4-sided "stone" that I use to hone at the moment, I got it not knowing that I wasnt totally suitable for Hss tools ( though I have resurrected a couple of carbide inserts with it ). I'll have to look out for an arkansas stone.


Thanks for explaining that  :thumbup:

Hi

Don't get too hung up about getting the angle spot on they are only guidelines as long as you get them going the correct way and don't have too sharp an angle as this will only weaken the tool:- aim for 3 deg but no more than 10.

In a jobbing shop they wouldn't worry to much about it as long as they got the job done:- but, In a manufacturing volume production environment, a lot of time and effort will be spent getting the tooling correct but that is only because they want to optimise output and efficiency

In a home workshop, find something that works for you and have fun.

Hope this helps

Have fun

I find if you use white spirit instead of water to lube/wash the diamond stone it doesn't clog up. In fact it will clean up a stone after it's been used dry.

Forget using WD40 with diamond, somehow it doesn't work as well as it does with a normal stone.

Diamond stones cut much harder/faster than their grit size would suggest. If you want a fine finish for tool grinding then use a fine diamond stone and you will have no problems.
