ditchman Posted May 30, 2019 Author Report Share Posted May 30, 2019 first spring now done............the old spring thickness is 2.997mm.........(slightly less than the blade) and the new spring thickness is 3.274mm.....which will allow polishing fitting etc and any anomolys during heat treating .......... when i added up all my bits of time this one spring has taken nearly 5 hours to make.........ive really got a sense of acheivement with it as well........at the hinge point i have beefed it up a little bit (left more meat on it....)

B725 Posted May 30, 2019 Report Share Posted May 30, 2019 Do you measure the temperature with your bare hand's to make sure its just right. Quote Link to comment Share on other sites More sharing options...
ditchman Posted May 30, 2019 Author Report Share Posted May 30, 2019 you know when it is right for hardening by the colour the steel becomes non-magnetic then it is the right temp' for the quench to..harden......... Quote Link to comment Share on other sites More sharing options...
fatchap Posted May 30, 2019 Report Share Posted May 30, 2019 (edited) The magnetic test works most of the time but you need a different plan with certain stainless steels. Austenitic stainless steel for instance has a very high chromium and nickel content and as such is non magnetic but is pretty damn hard in the first place.

fatchap Posted May 30, 2019 Report Share Posted May 30, 2019 I try to stick to D2, I bought a flat bar of 01 tool steel last week and the manufacturer was kind enough to put the "ingredients" on the packaging, for instance 1.2% molybdenum, 0.7% tungsten, 0.8% titanium, I could go on the list was quite extensive.

figgy Posted May 30, 2019 Report Share Posted May 30, 2019 Surprised it didn't list traces of earth or mud too if they have to list potato. Quote Link to comment Share on other sites More sharing options...
fatchap Posted May 31, 2019 Report Share Posted May 31, 2019 Dry Roasted peanuts on the back......... Caution may contain nuts! Another that made me chuckle was a bottle of sparkling pure natural mineral water, filtered over a 1000 years through a mountain. Not sure which mountain maybe one on Mars as the list of ingredients and chemicals was quite long, why put Acesulfame Potassium in pure water, I believe its a artificial sweetener it did say trace which obviously makes it alright.
