      when I harden anything I quench in used motor oil. the way I understand it, the metal will actually draw carbon out of the oil to harden the surface of the metal. it has worked quite well for me for a while.


      Than you understand correctly....

      The key feature to harndening is depth, normally this type of 'I did it myself' hardening is very shallow, unless you know exactly what you are doing, and what temp is needed, and duration etc etc...

      I'd say yes and no- You can take a piece of welding rod and quench it a couple of times and it's so brittle it won't bend 1/10th of what it did before you hardened it. But, it's also a small cross section so you don't need a lot of depth to do anything.

      This particular part isn't exactly thick either though.

      right, I usually call it case hardening. If I ever need to harden something this has worked for me, but then again I have never had to harden anything really thick, or under enough stress to need anything more than a good .020-.030 hardened shell/case

      I'd agree, I was speaking in generalities

      Hi guys
      just wanted to show you how we made our reinforced fork in tuning garage called Herc tuning in Cacak Serbia from the guy who makes all the champion geraboxes here from the first class steel from Kosovo that is normaly exported to Italy.
      He did my 02J gearbox to 6 speed one and incorporated my Quaife LSD into it.
      Ratios are:
      1. 3.7
      2. 2.2
      3. 1.6
      4. 1.25
      5. 1.04
      6. 0.87
      Final Drive 3.64
      First two remained OE for the comfortable daily driving without killing the clutch and the rest is killing machine.
      It is calculated for shifting on 7200rpm and drops only to 6000rpom where I do have 375Nm - meaning pulls like hell all the way.
      Than we added reinforced fork that I have seen at inaeng.
      Ours looks even better I think.
      Still no billet pinion brace but to come.
      I'll share my results than.
      Here is the link to the pics:
