this is one of those things, like Frameforum and WikiPedia and imdb, that make the internet so flippin' sweet.
i have access to a milling machine this fall, but apparently almost nobody at my school knows how to use it. but after learning a bit from this site and some practice and guidance i figure i oughtta be able to make some cool stuff.
of particular interest to readers:
boring with a vertical mill (looks like a good way to make a head tube sleeve from 4130 tubing, as previously described in an email to the FBs list)
an exhaustive glossary
cool background reading:
fundamentals of measurement and related lingo
also a sweet forum/message board
