    Pictures mostly but the hole is 1.5mm FYI.
    Used oxy/acetylene and brazing bits.
    Pretty sure it will work.
    See pics below,

    Your brazing work is nice.
    I think that should do fine, and probably took less time than making replacements from bar stock would.

    Have you checked the spray pattern yet? It should be fine, but I'm am curious to see.

    Forgot to mention that the one that looks like copper is 6mm copper but the other 2 are mild steel pipe with an OD of 4.5mm recycled from the back of a de-gassed fridge.
    It allowed me to add a bit of force so on one I drilled in with a 4.5mm drill and hammered the pipe in like a nail, it was a very satisfying sensation haha.

    The bit of wire on top is in lieu of the broken off tiny dowels. A straight cut over the hole to the other side with a hacksaw and a piece of high tensile wire brazed in. There was no way I was going to be able to get that tiny dowel out.

    You are right kmoe once I got it together it was a 15min job and would have been shorter if I didn't over do the brazing and have to file it off here and there.

    BTW: the main body is damn soft as you can see by the left over marks from using the vise without guards. You can actually mark it by tapping a screwdriver on it and also deform it by squishing it too hard in the vise.

    Good job cds1984 exactly what I would do if I needed to. The ' tiny dowel ' .. is that a Roll Pin?

    Yes, roll pin which is just as useless as the size that it is. Hopeless strength wise. One bend and ... SNAP or maybe 'snap' since it is so tiny.

    All the pin does is locate the nozzle in the bore so it doesn't spin. Plenty strong for the application, and usually they don't break.

    2 of the three were bent. I wonder if they naturally get bent from being in an engine but at any rate both of them snapped when I gave them a tweak. The last one I pulled on purpose from the nozzle.
    Still I should just work out a way to re-engineer the nozzle so no matter how much the HIVO chain goes out of whack it wont touch it...
    Next time!

    Tried to take a picture of the spray pattern but just couldn't... needed a third hand!
    But it looked good and depending on the oil pressure it would be coating the starter clutch and surrounding bits pretty well, i reckon.

    It's in and I have 2 spares.
    The new hivo chain, from Len a ways back, is miles away from it also.

    Just out of interest, did you measure the 'stretch' on the old Hyvo chain.....??

    I didn't but with the engine upside down and split the old chain was literally sitting on top of the oil spray nozzle with slack on either side of it and with the new chain it is not even close to touching it.
    Not scientific but good enough to see the difference.

    No idea sorry.
    If you are wondering what condition your nozzle (and chain) is in, you can access it from behind the alternator cover.
    Pop the rotor off, take out the three torx bolts and rotate the cover until the oil spray nozzle can be pulled out.
    Easier than splitting the engine to have a look, I'd say.
