I’m a mechanical engineering student with a fairly open brief for a short project. Have to draw a 3D cad model of a mechanism and do some motion analysis. So i thought i’d ask the fine folk of slrpnk if they had any projects that need a bit of ironing out.
Probably best suited if you have an idea and want see how the parts might move in 3 dimensions. I’d be able to tell you stuff like how much force/torque is in a particular part, letting you know how strong bits need to be.
Has to be a mechanism of some sort that i draw from scratch - let me know what dimensions i need to accomodate. And i have to present it to the class.
Sure, I’ll work off that copper coin lad’s dimensions and try and make it adjustable like the smelter. Could you point me towards an example of the little coffee can forge?
Sure! Generally they’re just an old coffee can with a thick layer of plaster of Paris and sand or firebox cement on the inside. They cement in some torch parts so they can attach a can from a burnzomatic torch and blow fire into the small, contained space from the side while having a hole on the front (usually with some loose firebrick for a door) to insert the work.

I don’t know that the design itself is actually applicable here, just that they’re a good demonstration that even with a small forge, you can do some pretty cool blacksmithing.
In practice I think a solar forge would have to be open from the top, and couldn’t really benefit from the tight space confining the heat, so it’d probably be closer to using a portable ferrier’s anvil like you might see reenactors use at the fair, or something like this:
Though it’d look more like that artist’s smelting rig with the big lens and all.
Thanks! I’m really excited to see what you come up with
