ditchman Posted May 27, 2015 Report Share Posted May 27, 2015 dont let it get hot when you grind it....keep dropping it in cold water......... Quote Link to comment Share on other sites More sharing options...
CaptainBeaky Posted May 27, 2015 Report Share Posted May 27, 2015 Belt grinder or linisher, take it slow, and as ditchman says, keep it cool. Work out what you are trying to achieve BEFORE you pick up the tool! Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted May 27, 2015 Author Report Share Posted May 27, 2015 thanks gents, I know about not over heating the steel, I've ground and sharpened more chisels over the years than you've had hot dinners now when I used to work at the foundry, we had some serious kit for doing stuff like this in the fettling shop and it was relatively easy, now all I have is a grinder, a belt sander, a dremmel, and a workmate. my water fed wheel is just too slow, i'll have a play and see how I get on.

darren 67 Posted May 27, 2015 Report Share Posted May 27, 2015 Take a look on YouTube at trollskyy knife making. Some good tips on grinding a blade and on one he has made a guide to hold the knife in. Quote Link to comment Share on other sites More sharing options...
bigman Posted May 27, 2015 Report Share Posted May 27, 2015 Post up some pics mate that might help , a scotchbrite belt on a belt grinder would probably bring it up nice Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted May 27, 2015 Author Report Share Posted May 27, 2015 needs a bit more than scotchbrite buddy, it was originally a leaf spring or something similar, the previous owner/maker wasn't very kind to it, the steel is hard as and it'll take some doing to get it tanto shaped.

kent Posted May 28, 2015 Report Share Posted May 28, 2015 Always consider annealing it shaping and then re- hardening / tempering if there is a lot to do on higher carbon steels like spring steel. Not saying this is the way but if you have a bit to do you are bound to need to re-treat it anyhow, might as well work in the softened state as I see it Quote Link to comment Share on other sites More sharing options...
