BeaverNZ Posted March 29, 2017 Share Posted March 29, 2017 I have access to track springs from diggers as they break some times especailly they forestry harvesting diggers as they take them in such crazy steep ground they wear a 5 point harness just to stay in the seat!. I have just yesterday forged one of these in the power hammer to make some tooling out of it ended up being 40x40mm square. The strongest track spring I have had apart in the press was a 45 tonne spring. Its going to be interesting to see what properties they have Quote Link to comment Share on other sites More sharing options...

I'd hate to have to beat that into bar stock! Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 29, 2017 Share Posted March 29, 2017 Cedarghost guy: When you're replying to a post with pics please delete the pics unless one has specific purpose in your reply. It really saves bandwidth, some of us aren't on broadband, some may even be on dialup. Thanks, Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...

Don't worry about it, it was a FYI reply. Hey, dialup put me in contact with the world and blacksmiths all over the world. Frosty The Lucky.

cedarghost Posted April 2, 2017 Author Share Posted April 2, 2017 I know one thing. This steel is hard to move. I've heated it up 4 or 5 times to bright orange and beat on it and it's hard to budge. Quote Link to comment Share on other sites More sharing options...
Will W. Posted April 3, 2017 Share Posted April 3, 2017 I didn't see it mentioned yet, so worth noting: be careful of micro cracks in the steel when working with springs. I personally have not had to deal with it yet (knock on wood) but I've read horror stories of guys working on an extravagant knife from a spring, just to have the piece break later, likely due to a micro crack.

ThomasPowers Posted April 3, 2017 Share Posted April 3, 2017 Why we Don't suggest using part of a broken spring and if possible using low milage automotive springs, a place that does lifts and lowers will often have pretty much unused springs on the discard pile... Much harder to source low use large springs! (But they probably have been engineered for a longer use life too; as the down time costs are often way higher than the material costs) Quote Link to comment Share on other sites More sharing options...
