Like Jim, I have seen few examples of turned pegs in homes and barns, in my case I have come across two exceptions, both atypical in various other aspects also. (one had a trussed and suspended floor, the other the only example of centered braces in an SR frame I’ve come across) Both were built by wealthy industrialists, bringing weal (read that: conspicuous consumption) back to their hometowns.

Trunnel – is still in common usage in the Bridgewrighting community, and (like the wiki suggests) is used in referring to the large pins that are common to bridges. As an aside to that, (and in contrast to the norm) turned pegs, even in small diameters are common to bridges, even early examples. This likely due to the constant forces found in them, and the desire for full bearing on the pins, and the logic of adding a bunch of 1” to the 1 ¾ “ order. These orders perhaps filled on typical lathes early on, but eventually this led to the advent of specialty trunnel lathes –
