Has anyone tried metal casting. Would be interested in seeing your set up if you have pictures.

On Youtube.com there are videos about casting parts for scale model hit and miss engines. just wonder what experience anyone has had.

My understanding is that you will have to make your own pattern a bit over size for there is about 8% shrinkage as the casting solidify s and cools. This means that to get the same weight you can't use an original. This shrinkage will probably affect the mounting hole spacing too. If doing it for yourself a little trial and error will get er done.

We need an original to make a pattern from and go from there. A Clay mold of the original to make a new oversize pattern with a pantograph like they do with coins?
