So, I've also been experimenting with a kind of autonomous golem factory, and it's useful to note that any equipment made by members of a race is by default sized properly for them. So if you're using smith golems to forge equipment, it all comes out the right size*. Admittedly, zero quality, but smith golems don't sleep and can be added to very small burrows, so production is at least fast.
If I get somewhere with it, I'll make a post, it's quite a nice abuse of golems for fun and profit
*The same holds true for ogres on the orc mod, who genuinely have no comparably sized creature
What weapons are you using for your golems? I'm thinking great axes, ideally tungsten, for mine.
