        Not much to show this morning but here is the basic foundation, ready for that nice Victorian Cottage to sprout up.

              The planking has been applied to the deck area and after a bit more cleaning up of the edges it will be painted light gray.





              I forgot to post the photos of the molds so far, the two piece mold for most parts and

              the one piece mold for the two sizes of scroll work.

                Going to be interesting to see how those two part mold pieces are going to turn out. I would think some vent holes to let trapped air bubbles out might be in order. Here's wishing you good luck on your casting.

                  Not too much time to work on the project over the holiday weekend but I did find time to paint

                  the decking gray, add a white topping strip, and do some planning and interpreting the photos

                  again, and again, and again.

                  Also, I will be needing a zillion of those little balusters I am casting so I took five of

                  my castings and made a new little two piece mold in which to cast them five at a time.

                  Bernd, thanks for the advice, much appreciated, however so far the casting seems

                  to be going OK. I'll try to post a photo soon.

                      Thanks Jerry.

                      These all have to be cleaned up but it's a sample of the castings I am getting from those molds.

                          Bob, looks like the Santos casting company is in full production mode, turning out quality castings once again!

                            Bob,

                            I'm impressed with how good those castings turned out. A closer look at your mold shows no sprue gates. How'd you do that?

                                Mike, Greg, Bernd, and Ray, thanks for posting.

                                Bernd, sorry for the delay in getting to your question, I have not been on the Forum much over

                                the holidays. There are no pouring gates, this is called the "squash" method. I have tried to

                                explain it several times but I know it is hard to describe. Here it is:

                                1. lay the two mold halves, open side up, next to each other.

                                2. mix up a batch or resin and carefully pour it into both mold halves slightly overfill

                                (it is messy, work on a bunch of newspapers).

                                3. This resin sets up so fast you can see it start to thicken like heavy syrup.

                                4. as it thickens you can pick up one mold half, turn it face down and quickly plop it

                                onto the other mold half. Quickly throw the flat board onto the molds and add weight, as

                                much as you can, it will hold the mold halves together.

                                5. let it fully cure, I leave it about a half hour, then demold the parts.

                                It's a thing to get used to. If you do it too fast you will loose much of your resin and if

                                you go too slow you will get a thick parting web between parts. You will loose some parts due to air

                                bubbles but it's easier than trying to get the mold to fill through a too small gate.

                                I hope that helps.

                                Bob
