I have distilled HF out of powdered fluorspar and sulfuric acid in a home lab, from a lead tube I rolled out of sheet. I was borrowing steps described in an industrial chemistry encyclopedia from the 1860s. (All I did with it was conclusively etch/dissolve the glass receiving vessel. I didn’t have a proper receiver made of lead or paraffin-coated glass.) This sort of thing is admittedly quite hazardous. But if you look at older chemistry publications, you might be surprised what is possible with relatively crude equipment.
