I built the new Italeri 1/12th kit when it came out and was quite impressed with it.

I always threatened to make some decent wire wheels (old school - ali, lathe, drilling lots of tricky small holes etc) for it but never got around to it.

As Iím doing a lot more with CAD now, I thought I would have a crack at drawing and printing some instead.

Just for fun, and with no expectation of success, I thought I would try printing them as-is:-

Amazingly, my poor little printer very nearly managed to do it.

However, it did prove that scale thickness spokes would be too weak using this technique, so back to the drawing board (screen? We need a new expression in 2021 I think)

Welcome to my Ďpatentedí print support/jig/stringing guide concept!

http://www.scalemotorcars.com/forum/images/imported/2021/08/66.jpg

The hub is printed separately so you can get at it to clear all the spokes holes, they are mostly printed but you cannot guarantee they are all free from resin at .3mm diameter, so I run a drill through them all. This is very easy as even if they are slightly clogged they form very obvious pilot holes and pull the drill down the correct path.

The hub has a key way, which is then screwed into the former. The printed guide on the jig shows one of each of the 6 different stringing patterns to get you started. Finally the nipples are all printed separately too and just slide on. Lock the whole thing off with ultra-thin CA and youíre done.

This isnít quite right or finished, but for a first prototype, Iím quite pleased with it and it proves my little system.

Oh my!

Did you hear that?

All over the forum? Half of us just said "That's how to do it!" -and the other half moaned!

And here it is with paint compared to the full size original.

Got hold of some 32SWG steel wire for the spokes, which is a bit stiffer and much better to work with. Not sure what this in AWG it’s .3mm anyway.

Mainly though I have been tweaking the design so that all the holes print cleanly, and no drilling is required at all now. This doesn’t sound much, but actually it was quite a big deal and took many attempts to perfect.

Thanks for looking,

Scale this up to 1/8th? And you've got the market cornered! With the popularity of this kit, there will probably be more in 1/12th. -and of course the Pocher crowd are always looking for improvements to those kits.

I'm gladden to see you put your considerable talents towards something creative, and finally put aside those plans for world domination!!!! gringrin

Not necessarily - this is just a bit of light relief from hollowing out the volcano.

I’m just finalising the instruction manual and website, and will be producing these for sale very soon.

I finished writing the manual for my wheels today if anyone is interested in seeing how they work

https://unobtainium.digital/manuals/alfa-8c-wheels-v1.0.pdf

My website is also nearing completion where I will be offering these as well as other resin printed products very soon.

There is no substitute for straight real wire in wire wheels as Nick has demonstrated.
It can be done with thin round plastic rod but would not be as robust.

We heard the eruption in NZ. A lot of low booming that went on for a long time. Tonga is 2,200km away (1367 miles...)

Hello Jo!

I was wondering if you had heard it. That is amazing!

I think that world-wide there are a hundred or so active volcanoes. By geologist and vulcanologist standards, of what constitutes an active volcano, we have several here on the west coast of North America, and a "Super Caldera" is another way at looking at Yellowstone Park.

Our Mt. Saint Helens of 42 years ago.

But what happened at Tonga, . . . we're not getting much news here in the states as we are preoccupied with our own madness, but I heard that the people of Tonga were unable to hear anything but the booming. Our weather instrumentations, barometers and such did record the passing of it's shockwave, and we're pretty far away.

they are covered in about 20cm of ash. clearing the runway for landings. Oz and NZ aid arriving but the undersea cable to Fiji is broken, so very little comms. Will take 4 weeks to fix. In the meantime NZ Tongans filling containers with relief aid, especially canned goods and water. NZ Navy has taken desalination plants to Tonga. This was a big eruption....
