When doing split molds, I use them as locating pins. Once the plug is done, a parting board is cut to the dimensions required, with the shape of the plug in the middle. Marbles are imbedded halfway using body putty, the parting board is installed, waxed, and the side of the plug where the marbles are, is laid up. Once the resin has cured, remove the parting board, clean and wax the mold face, lay up the other half. The shape of the marbles will make alignment perfect every time. Picture show a marble still imbedded in a parting board with removed marbles beside it. Other picture shows the locating pins in a mold set. Ping Exactly Ping! Good thinking, thats how i tackle mine too. No need faffing around with embedded sockets that need to line up in the first place to when building the mould anyway. Half spheres, n then bolt em together. easy as.

These are used for mould location when metal casting. Halfway down here: http://www.stationroadbaseboards.co.uk/cart_dowels.htm

Then I generally use M8 bolts and penny washers to clamp them up. www.LedonRacing.com Professional motorsport services & composite production / repairs.

Half spheres make great way of interlocking your flanges when used during the moulding process. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant
