I've seen a few videos of him making various motorcycle parts.
Great inginuity and use of limited resources but also probably explains why the pinch-clamp on the fork leg I bought from ebay India snapped when I tightened the bolt. He's got a pot of nasty aluminium scrap with paint, green sand and all sorts of ancilliary nonsense thrown in and no facilities to anneal, heat treat or age the metal afterwards.
I can't help thinking this was made in a not dissimilar facility. I suspect many of the cheap RE parts on ebay are made in similar setups with the marketing being done on a smartphone. You can't fault the entrepenurial spirit though.

I don't imagine that used brake RE shoes are in short supply, even in that part of the world. There's no reason why they cannot be re-lined, just as that newly cast replica needs.

Depending on how long he has been doing this, I’d like to look on the other side of the wall behind him, he throws all detritus over there!

When I took O level metalwork in the very late '70s we used a very similar process to cast parts to make our own steam engine. Even then H+S was tight.
I hope be benefits from videos of him.

Here's our new friend again with what looks like an alternator cover.

All very enterprising and ingenious, but if he's using an original component as a pattern, the finished result will be slightly undersized. Foundry pattern makers usually make the patterns slightly oversize to allow for the shrinkage of the molten metal on cooling.
