Default flecktarn experiment

This is the flecktarn experiment.
I bought a 1m silicone tube and cut it into little pasta pieces.
Then i used copydex glue to fixate them in the silicone mould.
As you can see, i used copydex to seal the connections between the tubelets.
This way the resin does not flow into the larger cavities.
I used different colors and only 3 colors instead of 6 ...
but this is only my first try.
I took some progress pictures.
After the first color i pulled some of the tubes...
filled the gaps with the second color...
pulled the rest... filled the gaps with the third color.
I spilled a lot of resin around the actual holes... so the result will be less colorful.
At this point. i could drill holes and continue filling them with different colors,
but i will leave it like it is...
The silicone tube-cut up´s can be reused.
It is recommended, to leave them a little bit longer than the depth of the mould,
otherwise it is difficult to pull them out of the hardened resin

Any recommendations what slingshot template i should use with this?

Cool stuff! How does this compare to "just" drilling holes? Would you say it is easier?

I believe drilling holes is the easier method.
The only downside to the drill-method is,
that you may have problems getting the holes interconnected
to form larger areas in one color.
Maybe not an issue, if you have a drillstand
and a vice to clamp the resin in...

the downside to the silicone tube method is, that you need to take the resin out of the mould to pull some of the tubes... and that means, the new resin flows underneath the first stuff. Thats not an issue of optics but an issue with the amount of resin you need... i had to pour each color twice because of that
Now that i think of it, that would apply to the drill method as well

You know what?... i am going to try that and compare both results... thanks onnod

Default Heart of gold

Work kept me busy last weeks so the new flecktarn experiment is not yet ready,
but i had some other experiment running that i finished today.
It was done with 2 different colors silver/gold and i wanted to know,
how these two colors react when poured into the mould without further mixing or stirring.
As you can see, i filled the mould with the silver resin first,
then i poured in the gold resin along the middle lines of the shape.
The gold resin sunk into the silver resin and left a thin line where i poured it in.

When i started to shape the slingshot, the golden resin emerged presenting some nice, almost organic, patterns.
I made a core from golden resin alone
and added white acrylic glas layers for strength.
Sanded and polished.

Not my favorite color, but an interesting experiment

Sometimes i think it looks more like some caramel candy
...but that may be my stomach talking

Interesting! I keep saying this, but I just love seeing your experiments. This one reminds me of marble, with the delicate and characteristic (is that a word?) lines that make each piece unique

Default kite mould + white tiger resin

Something inbetween...

better tigerstripes than in the last camo experiment and a mould for
casting a full kite frame. This opens new opportunities

That was an understatement... it looks aweful

Nope... drilling more holes is the only way to make it acceptable.
This needs more colors.

Also the flecktarn made with the drill is much more promising.
i used a 6mm drillbit instead of the 10mm as the silicone tubes had.

That alows a more detailed pattern, which i believe is more fitting for a slingshot. Some work in progress pictures.

The good thing about the drillingmethod is, you can use the cut-outs to cast a new slab... so its multiplying

Very interesting to see your progress!
The flecktarn is coming along nicely
Those drilled plates look like they got attacked by a machine gun, very fitting

Thats true
I am doing at least one more color, maybe 2... there are limits to the number of colors i can create
