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! 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
