Nearly Finished Cylinder Pattern

A nice job

Watch out for the draft angles on the fins - a thin coating of graphite helps to get the mould released from the sand

Good luck

@Martin Aislabie The fins are going to be the hard part. Thinking about it, near the parting line the sand would practically have to slide sideways on the fin, making the draft angle zero. I have a feeling this will require a lot of fine tuning. I would start now but I just went outside and found my plastic tub of greensand had a hole in the lid. Consequently the greensand was at the bottom of a block of ice. This may take some waiting.

Thanks,
