Yeah, you'll probably need fork parts and braze-ons. Off the top of my head:
front dropouts (I suggest the socketed ones)
rear dropouts (ditto)
Split cable stops - 2 for top tube, 1 for chainstay
Downtube shifter bosses or 2 more split stops
Water bottle bosses (4, probably)
Rear brake bridge and reinforcements
Rear chainstay bridge and reinforcements
Front derailleur braze on (if desired)
Under-bb cable guide
I don't think I missed anything, but someone will correct me if I did.
You will also need (at minimum, in addition to torch, hand tools, etc.):
* Brazing material. I just built my first frame (took it for the first ride an hour ago after finishing the component swap late last night) and used primarily 1/16" 56% safety silver, about 4 ounces total. I also bought some 45% safety silver by mistake, which I used to braze my seat lug and seat cluster. The slightly higher flow temp made it easier to do multi-step brazing that occurs in this area. However, the 56% flows better. I want to try brass with my next frame.
* Brown paste flux or whatever is appropriate for your brazing material.
* Several good files...you can never have too many.
* Emery cloth. I like the stuff that comes on a roll, 150 grit is a useful grit.
* A small wire and a small brass brush
* a 4' straightedge is really useful to have, as is a good smaller steel ruler and a set of calipers
* A Dremel tool with 1/2" sandpaper drums is really useful to have
Good luck and have fun. You can also download the old Paterek frame manual here
