JeffIf you would like the file for the mould I can send it. The CI casting was £50 plus £8 to post to me. If you are tempted with Aussie post, let me know. Would you be prepared to share your crank case 3d model so I could AL cast that here?Happy to compare notes as the Midgets develop.Best regardsIan
Jeff it would be a lot cheaper to just use some 75mm round or 55mm square cast iron bar, it's not as though the casting has the fins cast in so you are only saving a small amount of lathe work and will be sure of sound material.Cost here would be about £12 rather than the £50 Ian paid
