Casting Tutorial

[James W.]

The tutorial is great, but I did have a question about venting a human figure with its arms outstretched and holding weapons. Am I likely better off positioning the figure head up or head down? How extensively should I vent the figure? Just at the end of the weapons or part way down the arm as well?

I know this is all somewhat dependent on the figure in question, but I hoped that there might be some good general advice when resin casting models with "spindly bits" .

Thanks.

It depends on the casting process you're using. Vacuum? Pressure? Both?

For vacuum + pressure you could get away with vents just at the ends of the arms. Is the head a separate piece or sculpted as part of the torso? If the latter than feet towards the sprue is really the only option...
