Got on the lathe and mill recently and machined a billet intake stack for the SU-HS4 carb that is going on the VW 2287 build. I know spun aluminum stacks can be bought pretty reasonably, but I wanted to see if my small machines could do the job - and I needed to explore tapers and splined curve machining. Pretty happy with the result. Material is 6061 aluminum. The outside is tapered 10° (20° inclusive), and the inside is a progressive splined curve which is matched to the carb's venturi.
