Pouring Resin into molds

Here we start to see how I make resin recast parts with the stamps I made before. The first thing to do is to find the resin to use. The first times I used the italian Prochima resin that wasn't to much good but was the only I find at a good price and easy to use. Now I use a new resin that my friend Roberto buys for me (Ureol FC52 Iso) that mixes the two components in 50-50 and once casted is white and it takes very few bobbles.
For casting we need a wooden plane, almost 50cm x 50cm (one that you can ruin) that you cover with old newspapers fixed with scotch. Place your stamps on this plane and take some little plastic cups where you mix resin, take also a little iron rod to mix it and take off bobbles from stamp. Place the plane near a well ventilated place, better near an open window because the resin isn't good to inhale. Use two graduated syringes to help mixing equal parts of resin in one cup, remeber that the resin takes (there are time differences on different resin) 5-10 minutes to start hardening so start mix it (as written on the box) trying to not create to much bobbles and pour it into the form of the part into the rubber. Try to find the right amount of resin to fill the stamp and remember to put some dropps of resin on the holes into the cover part of the stamp. Now before the resin starts ti cast, you have to turn into place the cover as seen on the third figure from SX, be quick and push down firmly but not to hard to deform the stamp.

Just give a little push to the cover and you may see the excess of resin come out of the borders. Now you have to wait that the resin hardens enough to take off the part form the stamp without deforming it. I usually make 4 groups of stamps so I can prepare other ones waiting for the others to cast. When I see the resin that went out from the stamp is hardened and isn't no more deformable I take one corner of the cover and I peel it away as you see in the photo under here.

Now you only have to take off the resin parts form the rubber mold squeezing a little the rubber stamp that doesn't broke and you have your recast parts made. Leave them to rest for about 24-48 hours so they harden at all and are ready for making your models.

Final Considerations: Remeber that this is't the the best way at all to make recast but works great for me, try starting with this way and make your own style. The hardest thing is to make good rubber molds and you may tray to see how the piece has to be put under rubber. If you have other questions email me.
