[QUOTE="richuk, post: 322812, member: 14889"] Thanks for the response everyone. Good news following everyones advice i managed to avoid the dreaded porosity. I increased the size of the reservoir, and added a plastic stick to act as a chimney to allow the air/gases to escape. We no longer cast with a flame/torch anymore, we've been using an induction casting machine for a good 8 years now. Alloys we aways sandblast the old and add fresh alloy to each casting. I used about 17 grams of metal on this one following on from what was advised above.
