But I think your missing one very importent bit lateral force, if the wheel is only done on a 2x spoke the wheel rim will not be tight enough to the hub.

So when the wheel is fitted to the model and all the weight that is pushing down onto the hub, the force that is taken up by the 3x spokes with be a lot weaker on a 2x spoke and this could lead to the wheel disforming under the weight.

Hi,

I understand what you are saying but will crossing over an extra spoke really make all that much difference to the stress levels? on the real car I assume yes hence the design, but this build won't weigh 1:8 of the full sized car - in fact no where near it so I'm not to sure that counts and also surly the tires will absorb some of the downforce weight as well?

But hey I'm no physicist so what do I know I "copped out" and glued mine which will add strength - but if I used tape that may/will indeed affect things later on.....we'll see

A car model of this size reaches about 10 kg in weight. That's quite a bit of downward pressure for the wheels to take especially considering the car usually isn't moved, so the pressure will always affect the same area, for years and years preferably. I'd be very wary about a two spoke pattern holding up to this. You just need one to fail and it will cascade down the whole thing.

Hi,

I understand your point however won't a solid tyre offer more downforce support just like on a normal car? and then of course there's the wheel rim it's self which will also take some of the stress and adds strength to the spokes by locking them in? and then there's the question of the stress level of each spoke which is unknown so who's to know if they will hold up or not?

All I'm saying is that there are people, for what ever reason, several weeks after #5 came out are struggling with the 3x pattern and are understandably getting very frustrated and in some cases considering cancelling their subscriptions, it's just not worth putting yourselves under this amount of stress just because somebody/some people on this forum says its easy to do increasing the pressure to follow suit. This is supposed to be an enjoyable way to spend your spare time - so enjoy it!!

From what I've now been able to see of my own wheel, the problem will actually be one of fit.

With issue 4 done as in the magazine - 3 crossing points - the spokes from issue 5 go through the diamond pattern in the middle.

If you have settled on the 2 crossing points in issue 4, then the pattern of spokes from issue 5 will not settle correctly either.

From the troubles I had, the 2 crossing points configuration means the hub had quite a bit of lateral (sideways) movement to it. I don't know if this will 'help' or not in the fitting of the issue 5 spokes, but I don't think it's a good idea to carry on working on the wheel if you can't get the correct 3-point cross required. However, the 3 cross spoke pattern holds the hub rigid. (I still had problems with issue 5 due to the part of the hub the issue 5 spokes go through being able to turn 360° on the rest of the hub - which hole do I start on, and I kept choosing the wrong one!)

The problem I had seemed to be the final angle in the spokes. The one where I noticed the problem, the spoke was digging into the plastic because it was only making contact at the very end of the spoke. The bend where it went through the plastic was being pulled further away from the hub by the angle of the bend.

I used a pair of pliers to make the angle of the final bend (the one you push through the hub FIRST and holds the spoke against the outer wheel) closer to 90°. At this point the hub was not pulled as far off-centre, and I was able to get the opposite spoke - also having had the angle changed - into where it was supposed to be. Then I could work half way between these two points and do the same. Once all 4 directions were attached, the rest just fell into place as I got into the rhythm of adjusting the angles, then installing the spoke. Adjusting the next one and installing it, until I had finished.

For whatever reason, the mountain has already been made...

Further to my last message, below are incorrect (left) and correct (right) wheels.
A big difference which could bite later on in the model...

Have to agree and that this second wheel topic is heading for being locked as this subject has been more than done to death twice over.
