Hey everyone as I get further into my restoration I've found the tuner wheel and associated aluminium/diecast has fallen apart and appears perished like rubber? What do I do now? Does anyone have the parts pictured?

Thanks Mitch.

That stuff if it's die cast is actually predominantly Zinc based. Moisture makes a mess of this stuff and its a bit like steel, as when it oxidises it blows itself apart. I have a turntable gear box here made out of that crap & its also like a set of Leggo blocks (write off like this one)

Is there anything special about that slot? I have a set with a slot like that but its part of the drive, that appears not to be, but their could be an unrelated shaft coming through: Info?

I have a few pressed metal drums. Which may be an option, rather than print, or turn one. What does that big bearing journal run in?

The other bit could be made with two plates & two sleeves, or made as a solid block from round or square section adjusted to the height & width. That bit's the easy one. I'm surprised that the inertia flywheel, has not also disintegrated? I have ended up just turning new ones, if they are beyond epoxy resin (the old ones do not argue with the lathe).

Hey Marc
I have a mate that owns a foundary who has reproduced Victa mower bases in the past, hope he can help. The slot is for the tuner dial it runs off a gear through the slot.
Cheers,mitch

Assumed the smiley face was likely part of a drive: That's now sorted. Can I also assume that they were dumb enough to cast the gear out of the same stuff , or is it brass?

If it is brass then you salvage it & put a new tyre on it. I have done that to cluster gears. You should be able to do similar with pressed metal.

I am just seeing annoyance & inconvenience, not can't fix.

Hey Marc
Unfortunately the gear is cast as well so I will have to get creative ! The positive in all this is that the case is coming up a treat !

You actually may be able to get a gear printed, or find one used in some of these mechatronics & robot things with a close enough pitch an same diameter?

The same applies, fit it as a tyre & bolt it to the drum.

Long way from dead with this one.

Thanks Marc fingers crossed, only other hurdle is a 6G6G valve with an open circuit heater.

Since you have all the broken parts, consider casting it in epoxy. This works a treat for TV channel knobs etc. which need to be tough. The knobs I made for my AWA 209C were my first attempt at doing this and I nailed it in one!

You need moulding silicone and 2 part clear epoxy. Plus some disposable plastic containers.

You make a soft mould using the silicone and the original parts. Then, when this has set, take out the diecast bits, mix the epoxy and pour it into the mould. Once the epoxy sets, peel off the mould and voila! You may have to grind off some mould flash if you needed to make it a 2-part mould and drill the necessary holes.

If you mix the epoxy properly, this stuff is TOUGH!

Spray it with aluminium paint and no-one will be able to tell the difference.

This is where I got my materials:
