Each thing in its own time, and the time will come at some point...

Another Marui project - Ninja/Shogun 1 week 5 days ago #72275

As I found some tricks for the Big Bear tires, I modified my Ninja tires...


What to should I do with this? That's the question :-)

While working in the Big Bear tires, I learned a lot, and I got a lot of ideas... 

While I don't need Ninja tires for the time being, it's not the case for the Shogun and Coors. I have this silly idea it would be great if I can do something with injection molding, with a target to be able to work out a tire in one single action from a mould. That's the new step of this tire challenge. The Big Bear tire is still mainly conceptual, but I believe it should work but it is likely too big to work it as a test case. I need to work with a smaller tire first.

I decided it would be the Shogun/Coors tires. I would need 8 of them, and they are the same for both cars. Their format is quite standard, and this model can be used i quite a bunch of cars I have due to the rim size. Well I could probably use Tamiya Manta Ray or Hotoshot tires, but that is far too easy approach. I love challenges, and that's the way I learn :-)

So first step, I got my model reviewed to include lettering.


I wanted to put the model on the side, it will be a nice touch if I succeed to produce those, no one will ever have the same tires on a Vintage event, unless I decide it to be this way :-)

But since this tire is targeted to be used on both Coors and Shogun, I decided to put something else on the other side :-)


Once this done, I started by doing a square extrusion from the center, and cut the tire body inside that square and started to look into the profile.


I had a look at many videos, tutorial and readings over the last few days. They've started to flow in my brain, and it fuels lot of ideas :-D

IWhat I had in mind this night was :
- injection at bottom point
- central mould part will be a 3 floors tower with a central key used to lock those floors. each floors will be 3 or 4 parts. And the middle floor will be used to lock the first and third floor. and for unmolding, it will be used to unlock the mold.
- external side would be in 5 or 6 parts : 3 or 4 for the tire thread, on on a bottom, one the top. bottom and top will be locking the center key. and bottom will have injection ports. and top part will have to include air vents and provision for air channels (I may have to add another part for this)

NB: I did not even considered the foam tires of the Coors for this exercice. I'll tackle that later, but that will be far too easy for what I need now  :lol:

Well, that will be complex :)

Working out the center mould for a buggy tire, taking into account that once the center key is removed, each parts should be able to move freely through the cylinder which was removed.

and put the elements in a sketch. 8 parts are required for the middle floor to make the principle work.


And actually, it is probably less than this, as once the first part is removed there is more space.

Next : I will need to understand how many parts are required for the other floors.
