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.
For mixing of silicone and Reesin I use a fine balance.
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.
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 .
So I 'll do it then with the third molding.
In my annealing , curing works much faster and better.
And so the new shape still looks as a block and then separated .
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.
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 .Statistics: Posted by Edwin — Mon Nov 04, 2013 2:28 am
