First, just as a test if I succeed

Again, it goes a little further.

The Resinmaster are now cleaned and the flaws I have been milled, which takes incredibly long.
So now I could touch up with 2K filler this.



Tomorrow they will then sanded

Thus , in small pieces precedes it .

I now have first made me a little form , so that I can recognize and assess problem areas better. Because an error costs only a fraction of the material and the time that is necessary in a spin cast .



The resulting casts are as I did not expect at wide error-free , but now I know where I must begin . It is also a good test whether the chain so fit and works as I imagine it . I once put a piece of 1/16 chain next to my chain links . The 4 members now weigh even as much as a small chain .







In addition, I have also tried the same , the strength of the chain , but at 1200 N train me the wooden backing of the links is broken without that I could impress the chain.

So now I have started to build the spin cast , which is very expensive .
I use to drive silicone, which is then crosslinked in the oven.

For cutting I use the pressure lids .





And so I work now the master link into the mold.



Since I now have a lot of work , partly because the shape is not as usual in two parts, is special consist of 8 parts because of the complicated shape of the chain links .

Oustanding work so far Edwin!
Where do you buy the white metal for the casting?

Hi Murdock,

here is the link to a reference source for Zamak

Complimenti ottimo lavoro,
Non ho capito che tipo di silicone usi per lo stampo, è liquido o è tipo plastilina?

Congratulations great job,
I did not understand what kind of uses silicone for the mold, is liquid or type plasticine?
ciao ciao

Hi Marco,

The silicone I use is like a slightly firmer modeling clay, but high heat resistant and heat-curing. You build virtually the entire form in one piece and bake it for 2 hours at least 90 ° C in the oven. Then it is ready to use and more durable than the usual 2K silicones to pour

  ennesimo stampo interessante edwin e nota tecnica sul materiale usato nella tua realizzazione di quei pezzi , buon lavoro da robby62 ....  

Grazie per la spiegazione

thanks for the explanation

ciao ciao

And it is again a little further.

The silicone, which I wanted to use for the Schleudergußformen so well and stand hard it is, I have gotten off of this form . It's too tough and takes too long to create the such a complicated shape. If it can not finish in a certain time, the silicone pulls back away from the part and you have to edit it again. For simpler forms but I will still use it again and here I can also use it for other and is not lost.

So I ordered plasticine and 2K Sillikon and I thought from my experience a new form despite the limbs form should be in two parts possible.

So today I lift first the pot evenly filled with modeling clay and smoothed.



The master I then distributed evenly in the second step .



And so I am now doing the links individually embedded in the clay , which is quite complicated in this case, but maybe I can pour tomorrow .

Today I finished the chain links embedded in the clay and smoothed the surface of this.



So I could shape also teeming with 750g HT Sillocon and bleed.



Now I have to wait until tomorrow and hope soon to be able to pour the second mold part.
