Matt/MCW and I have been talking about this or a while, we both reckoned that the lower spike was too short/wrong angle in certain situations, particularly felling larger trees as well as blocking/cross-cutting larger logs.
So I finally extracted a digit and did something about it.
We'll soon see when I sink it into some timber if I got the angle of the dangle right
It appears the OE spikes are hardened steel too.
I've tried to locate a hardness tester to work out what/how far it's heat treated, but it doesn't look like there's one within 100km which is a shame.
I used normalised 4130 sheet (chrome-moly, I had some in the scrap bin) the same gauge for the new lower spike and it was much easier to cut than the material Dolmar use so ideally I'd heat treat these before too much use.
This was all done in a bit of a rush, a hole to match the OE one and a slap of paint will do wonders for the looks, Ideally I'd get some water jet cut or laser cut out of a single sheet, but I want to try them or see if they need adjusting and also get a set off to Matt to see if they pass.
it's funny, you can barely see that weld bead with the naked eye, but the wonky weld sticks out like dogs bollocks in a photo.

have some rep.
