Hello,

the making of silicone rubber moulds with a wooden box, plastiline, master parts (lifeboat, anchor, davit frame, davit arm, davit gear, ventilator motors) is relatively easy. For the pewter (tin) castings the moulding of a sprue and air ducts are necessary (as shown in former pictures).

The first castings in pewter (tin) of the anchors and ventilator motors worked well, see picture below. The lifeboat is resin cast. The figures are Preiser scale 1:100, the women are modified with dresses to the bottom.

I will show more pictures here in a few weeks, when the more complicated davits are finished.

Hello all,

I have edited this post after casting all the required parts in pewter (tin). To cast the davit gear was rather easy. The davit arms and davit frames wouldn't work from the start. After some experiments with tin alloys, etc. I modified the mould with a razor blade at some areas that wouldn't fill completely. Then it worked well, if the pewter (tin) was hot enough. On the photo below it has a silver color, after more heating it gets a yellow, then blue oxidation, then this oxide must be removed with a wooden stick before casting the parts. As you see in the picture the equipment is very simple, no electric oven, no centricast machine, etc. Warning: the handling of a small open fire with firelighters, wood, a gasburner, etc. and molten metal requires precaution! Not every casting is perfect, as you see in the pictures, so one need to cast some more parts by melting down the faulty parts.

In general, I think, these pewter (tin) castings worked rather well and quick to get sturdy parts. Otherwise I had to cast them in resin (davit arms rather brittle), built them all from scratch, in styrene or with brass etchings (which must be designed), or get them 3D-printed (which requires 3D-Data, etc.).

Now I have to file and finish the parts, which will require some time.

Regards,

Michael

Hello again,

to update this thread: here is a photo of the nearly finished anchors.
