What you might want to consider is "gluing" the spline parts together with JB weld (metal filled epoxy). You would need to warm it up to reduce the viscosity to get it to flow, and of course it cures faster once it is warm, so there's a bit of judgement needed. But I have had a few surprisingly effective repairs with plain epoxy. Advantage of epoxy is that you can always dismantle it again with a gas axe at a temperature of around 200C, which should be low enough not to affect the temper of the shaft. |

I might consider cutting the Landy drop arm, and extending it using your MIG welder. Further the cut is from the spline, the less force the weld will have to take. |

Mmm well I do have a mig set but not sure welding cast iron is a "good thing"? You're right, but it is very, very unlikely that the arm is cast iron. It is far more likely to be forged steel, which I have AC arc welded successfully, although for this job I think that I'd go for Bronze Welding using gas. |

Are you thinking of roll pins, aka spirol pins? Enough elasticity on diameter to be a tight fit in the holes, and very tough, especially spirol pins. Might be worth having something to retain it from walking out, if only a Jubilee clip. Plus the copper sleeve, plus one of the loctite/permabond adhesives to stop it wobbling and wearing. -- Kevin |

I would find a donor solid bar of similar size and heavily chamfer the edges I'm going to weld. I might allow some separation of a few mm of the pieces to assist in deep penetrating welds and keep going round until the weld is built up. Most of the strength of a bar will be on the outside so a modest weld depth, say 6mm+ or so, should be OK. |

Sounds like the only people who could steer this thing need to also have
body building first. Is there no other box that has a different gear ratio so more turns of the wheel are needed to steer it thus reducing the loads?

Are you thinking of roll pins, aka spirol pins? Enough elasticity on diameter to be a tight fit in the holes, and very tough, especially spirol pins. Might be worth having something to retain it from walking out, if only a Jubilee clip. Plus the copper sleeve, plus one of the loctite/permabond adhesives to stop it wobbling and wearing. Yes, that's it. Memory failing I'm afraid, even though I've a box of them in various sizes. |

Assuming the splines still mesh (and it appears they do) any "gap filling goop" will be in compression/tension depending on side of spline and direction of rotation. There could be shear with any rotational slop but the idea of the goop is to fully take up any slop... I'd assume that the is a bolt or nut at the end of the shaft that holds the drop arm in place with no movement up/down the shaft which would put any goop into sheer. -- Cheers Dave. |

Literally!:-) ;-) these splined shafts have threaded outer ends onto which a large nut tightens and stops the splined parts wandering... Ah, ok, thanks. So that would mean you couldn't easily make a spline adaptor so would be back to a cut-n-shut with the two arms. With that in mind and as others have mentioned, it might be worth a try at least with one of the 'liquid meta' type two-part epoxys, like JB Weld etc. Everything physically and chemically clean, maybe make up a rubber washer to go under the arm (depending on orientation etc) to stop the glue getting out and the same on top under the nut (washer?) till the glue has cured. Maybe get some suitably sized wire 'shims' to put down the splines to ensure the arm goes on with a light interference fit and that way it won't move the glue as it's curing (ideally 24 hours). Warm the arm and splines (if possible, hot air gun), mix up sufficient epoxy to be sure to do the job and quickly spread it over the splines and inside the arm (sufficiently to ensure the void is filled but not too much so it goes everywhere). Push the two parts together and remove and surplus and fill any voids, before putting the rubber washer and nut back on finger tight but ensuring the arm is far enough down to allow the nut to bottom. It might be worth putting some grease over the thread as precaution in case you get any epoxy on it. Leave 24 hours The idea is that the joint doesn't move (at all), because if it does, it will probably wear slack again over time. Cheers, T i m |
