Jason's frame is finished! This was my seventh frame and my first lugged bike. There is a lot more work that goes into a lugged frame than goes into a frame that has been joined with brass fillet's. With a lugged bike you not only have to miter the tubes to fit as tight as you would with a normal frame that is either welded or joined with a brass fillet but you also have to prepare the lugs so that they are spotless and that there is no contamination from dirt and oil. When you get the lugs they are pretty much right from the factory, which means that the metal has a lot of scaling that needs to be cleaned off. Once you have all of the lugs cleaned off then you need to make sure that the tubes fit inside the the lugs and can move smoothly but not have to much "wiggle room". All in all, lugged bike construction takes a lot longer than most other forms of construction. That said though they do have some advantages. Lugged bicycles have a very distinct and classic look that you can't really get anymore from the big names. Lugs can be customized in an infinite number of ways to give your bike a very distinct and beautiful look. Lugged bikes also allow you to use thinner tubing so there is no weight gain. Also, lugged frames can sometimes allow for a more customizable ride. Finally as you use silver to joing the lugs and tubes together you do not heat the frame near as high as you do with brass brazing or Tig welding. With the lower temperatures you will also not experience any where near as much distortion as the other joining methods produce, thereby giving you a frame that is very accurate without the need for as much "cold setting"
Lugged frames do however have some disadvantages as well. Their form of construction is painstakingly slow. From having to spend hours cleaning the lugs and ensuring a proper fit to the amount of clean up time AFTER the frame has been brazed it can take substantially longer to build a lugged road bike. Also there is a substantial cost difference with the lugs, with a decent set of lugs it can easily add another $150 to the cost of the frame, not to mention the rising cost of using silver (at least $40+ for 1 oz of silver). Even after the frame is finished you will still have consider a way to finish it. Typically I use powder coating, however with the lugs you will not get as much edge definition with powder coating and then all that hard work getting the looking nice would be wasted. The other alternative is having your frame painted, which can add another $400 to $500 to the expense of the project. Painting will however give you a chance to show off those beautiful lugs.
My prefered form of construction is brass brazing. This too takes a while to sculpt the mitres to create a nice tight connection, however once that is completed you only have to braze the frame together and do not have to mess with. There are other advantages and disadvantages to this process as well, but I talk about those later.
