    Yes, I was thinking of some sort of brass reinforcement, possibly to take some of the weight off the motor.

    start in the middle Is often the best way.

    I have opinions about epoxies and glues and when they will work.

    in general butt joints will fail in tension, wood being the least likely to fail.
    with brass and zamac it is a question of time. the drop was just sooner.

    if you can find a way to screw or pin the parts they are far less likely to fail.

    believe me getting such joints built can take serious planning.

    I'll stop here.

    This are the size in inch and mm.
    Driver measured on base of flange: 0,441 inch or 11.20mm
    Front wheel measured on base flange: 0216 inch or 5.50mm
    This it's the diameter of rolling surface, at the base of wheel flange, it.s conical

    That was my thought at first too, but after I looked closer at it, I just can't see any way to do that. It's such a tight area, since it's between the drivers and exactly next to the gear tower. Drilling a hole for a screw would remove so much metal that it would compromise the entire thing, and I don't even know where it'd go. Something I just noticed as I was making this post is that there may be space above the joint to make a reinforcing fillet with epoxy, but it'd have to be very carefully done. For now, I think I'm just going to hope it holds. It was fine until I dropped it, after all. Maybe if I'm very gentle it'll be okay.

    Hi Nerva,

    I might me wrong but I think that joint will fail in time. Zink and Epoxy don't make for the happiest of weddings !! One solution you could try is to cut a shallow slot with a dremel in either side of the joint and glue in a thin pin. See sketch. That's just one of many ways to help alleviate future tears !!! There are many others too.

    Good luck and keep us posted

    That's a great idea! The rod doesn't need to go through the metal, it only needs to be attached to the metal. That hadn't even occurred to me! I'll give that a try and report back.

    Okay, I've got it pinned. It looks and feels great, and the mechanism still runs as smooth as ever. I'm very glad that this issue got resolved. Next step is domes and running boards...
