Impressive work on that tyre!
Finally, all four wheels are done.
Next I need some rims, so I made a more detailed 3D model.
Resin printed again to save some time in the post processing.
Little bit of sanding and some spray filler and it was done.
Like the wheels, I now will make a mold to cast the rims in resin.
Need another set of winter wheels.
And it was time for the mold for the rim. This time a little different.
To properly demold it at the end, I needed to split the mold in two halves.
So I covered the first section with a little but of clay and added some
Mixed some silicone and poured it into the first half.
After about 6 hours of curing, I flipped the mold over and added vents and
a filling spout to the model. Then again mixed some silicone and poured the
Then I could cast all 4 rims in resin. Just need to take care
of the flashing and then they are good for painting.
wow, amazing work - I would be very intimidated to try that. Well done!
That's not silicone! It's Greek yogurt!
Lovely wheels, though. Even if they are made of yogurt.
Wow. Those weels are a piece of art.
Did you apply some kind of release agent to the silicone mold, before you poured the Smooth-Cast Onyx Slow?
If so, how? It is a quite narrow gap to do it uniformly...
Normally you dont need a release agent for this kind of resin.
If i would use it for more than 4 castings, I would use some to extend the life span of the mold.
I have Ease Release 200 which comes in a spray can. When you use a brush after spraying
you can get it in almost any spot if necessary.
Now that all parts are printed and cast, I can start building everything together.
Started with the base. After filling all the imperfections, I followed it up with a couple
layers of spray filler.
After wet sanding, the base was primed black.
Although, there will be only a tiny part visible at the end, I decided
to paint everything. I dabbed on two layers of silver paint to get
a little more structure.
For a used look and to darken down the silver color, I applied a black wash to the parts.
No more bubble gum.
might add some greek yogurt later
I always read before breakfast. -Food on the brain.
You could just stop at the wheels and i'd vote moty
