Before I can cast the 2 Stroke engine block it needs a sand core. I could have 3D Printed the core box but chose the the more long, drawn out hands on approach. In this video I'll show you how I made a plaster sand core box.

I made some wood core boxes, then after using them a couple of times, stuck the halves in the sand and cast them in aluminum. Works out well when cooking the core mix to dry it.

Great idea! I'll have to remember that if I make cores that need baking.

Looking good. I'm surprised at how well the greensand core came out of the mould.

Yeah considering it's raw uncoated plaster. I'm going to brush some thinned epoxy on the core box to seal it and to offer some abrasion resistance against the sand.

Looks great. Though I wonder if venting of the core might be a problem. Can't wait to see the next video.

Thanks! For venting I'll just poke each end of the core with a tig welding rod and see how it goes.
