If I include the so together it is around 40 hours I needed for the link ....

But with the silicone mold for Resincasting it also goes further. Today I poured the second of three moldings. Once the basic shape was the most time consuming it is now a little easier and faster with each part.

After I first had to order and wait for the new shape silicone delivery let us go on .

I reassembled the Lego box and installed Eifll ventilation funnel made ​​out of plasticine and then poured the previously two -part form .

First, just as a test if I succeed - Pagina 4 16260380je

First, just as a test if I succeed - Pagina 4 16260379eh

The new silicone is slightly faster , smoother and it looks like it did not like the other problems with the plasticine. The surface remains smooth and unlike the previous unimpressed.

So I still do not like the shape , but I did not expected that I do it right the first time . Nevertheless, I now pour even a link from resin . Let's see how it is . But I will put the stock bars back first into the mold.

Now I've made a few casts with the form .

First, just as a test if I succeed - Pagina 4 16292901wy

I am satisfied with the form, as it is not yet , mainly because of this it would be greatly weaken a fundamental error produced by a small offset to the joints and too much air is still there. But that is not bad because I get to die here first as a lesson to see the knowledge for the very expensive spin cast .

So I have begun today from this experience to build a new shape.

Back in the Lego box , because the simple and works well . So I am learning slowly better to model with clay which also makes getting to be fun .

For casting the mold I have found a better now suitable for silicone and so the Grundbassis is ready.

First, just as a test if I succeed - Pagina 4 16293023nh

After the silicone is fixed you can have the difference between the old form and the new left , see right.

First, just as a test if I succeed - Pagina 4 16293024jq

Also the division of the form I get a little modify the three fittings to better separate . Here, the modeling for the second portion .

The new shape is finished ..... and works much better .

First, just as a test if I succeed - Pagina 4 16305619ya

Here you can already see that it fits better and more exactly to each other .

The small vent holes I made with a drill. With a very high rotating works quite well and I have exactly the right places .

First, just as a test if I succeed - Pagina 4 16305615ta

And so I'll have the same cast and a new chain link.

It still has bubbles , but this time it's useful with a little reworking.

Currently here is more of a learning effect for Resincasting in multipart forms of complex parts.

Although the surface is now reasonably well when I take the members out of shape, but sometimes only thinly over the bubbles collapse immediately when I edit the parts.
So continue in the trial.
Meanwhile I injeziere the resin heated to 40 ° C with a syringe in which to vent it before just fine. Simply compress the opening and pull the piston and already all the air collects at the top and the resin is almost clear.
I also heat the mold in my little annealing prior to about 40 ° C . so that the resin can be almost water thin pressed into the mold and leave bubbles almost like water. Nevertheless, I have always more or less air to different , changing places. Oh yes breather is already there.

First, just as a test if I succeed - Pagina 4 16351929il

First, just as a test if I succeed - Pagina 4 16351928nx

Now I just try out with what I can best repair defects. Apoxie is currently best suited , mainly because it after curing has a similar hardness.

First, just as a test if I succeed - Pagina 4 16351930xj

So I 'll probably have to build a third form with the experiences from the first two, but this completely interpret for the resin injection from below takes place in the form of a standing up so that the air is inherently displaced upward .

Thamk you Robby....Very Happy 

Resinform the Third ...

After I so do not get the bubble theme with the second form in the handle , I build from the experiences of the first two of a new form again . This I will only provided with a single vent and a filling .
But first, back to embed the link in plasticine. To get this even particularly smooth the putty beflamme I still very carefully with a small gas burner.

First, just as a test if I succeed - Pagina 4 16364355cb

For mixing of silicone and Reesin I use a fine balance.

First, just as a test if I succeed - Pagina 4 16364352el

After the silicone is networked I cut the surface tension raised by the edges with scissors so that the mold can lie flat .
so it looks from form to form better.

First, just as a test if I succeed - Pagina 4 16364356cx

First, just as a test if I succeed - Pagina 4 16364354kw

I share the top again with modeling clay and paint the silicone release agent before casting with a . For this I use a simple oil for cooking . But there is not any oil used . But you can easily find out by the silicone smeared with a thin film of oil. If it pulls evenly and thinly over the surface , you can use the oil , if it looks like water on a fresh car polish it will not work .

First, just as a test if I succeed - Pagina 4 16364359cu

So I 'll do it then with the third molding.

First, just as a test if I succeed - Pagina 4 16364363hb

In my annealing , curing works much faster and better.

First, just as a test if I succeed - Pagina 4 16364364rw

And so the new shape still looks as a block and then separated .

First, just as a test if I succeed - Pagina 4 16364366fp

First, just as a test if I succeed - Pagina 4 16364367ky

Now in the forms I make no vent in the casting sprue and more . These later I drill with a drill to the areas where they are needed.

Since I was approached because of the reuse of syringes.
I'll harden the resin is pull the plunger out and press the resin with a wire from the syringe. It is almost as often reusable.

First, just as a test if I succeed - Pagina 4 16364361vy

First, just as a test if I succeed - Pagina 4 16364362by

Even the thought of minimum weight of the tank I'll probably have to move by 5 to 10kg for top . I have today once weighed a chain link zamak and finished at about 55g the pair of chains will probably come to about 10kg . For this, the chain through their high weight but should run well .

Finally it works so that I can accept it .......

But first, how to proceed.
This time I have no sprue and vents built into the form , I would like to fill the mold in an injection .
Therefore, I now still need a filling and venting in the mold. This I am simply by i install in the appropriate places with the narrowest rivers jewels form a hole with a 3mm drill bit. With a sharp drill rotates very high it works wonderfully .

First, just as a test if I succeed - Pagina 4 16376469dc

Add the powdered form I put back the 3mm brass rods, which I do I need as a placeholder in the form of the bearing tubes of the chain pins .
Here you can also recognizable that my forms from time to time also be better and more accurate.

First, just as a test if I succeed - Pagina 4 16376467ak

And I can now press the preheated in the syringe and slowly vented resin into the mold. Here I swing the on-edge shape slightly so that there are no air bubbles can collect in corners.

First, just as a test if I succeed - Pagina 4 16376468vk

I press the resin into the mold without stopping until no air bases with the resin from the mold exit .. The syringe daf while in no case be drawn from the injection port , otherwise you again inflated a bubble of air into the system.

First, just as a test if I succeed - Pagina 4 16376465vz

After the resin was hard now see the link like this.
I still have a few bubbles , but only on the bearing surface of the chain link and I certainly still get away .

First, just as a test if I succeed - Pagina 4 16376466rq

And so the raw plastered link then looks . The few bubbles I can now easily repaired with a spatula and then the link is now usable.
