Commercial breweries don't typically make their own specialty malts, thats usually done by the maltings, however, since some of us like to do everything ourselves, here are some links:
Scroll to step 5 here: http://www.bodensatz.com/upage/index...brewer_malting
Lots of info here, although it's basically advertisements for each malting company, might have to look around a bit: http://brewingtechniques.com/bmg/beeston.html
Palmer is always a good source: http://www.howtobrew.com/section4/chapter20-4.html
If you don't see what you need here, give us specifics of what you want to do and I'm sure someone can help. Crystal/caramalt is a little different, basically it is "mashed" whole after malting, then dried and kilned to different degrees/times for different lovibonds.
Keep on brewing my friends
Edit: I guess Bodensatz got theirs from Palmer, I have more links on my laptop, but I left it at home, I'll post if needed.
Edit2: I've done a little here (page 12): http://www.homebrewtalk.com/f51/happ...9/index12.html
