The repair is made up of a few processes.

First is the prep. Removing the paint for a few inches from each tube involved, including the top tube. Since this is a complex joint with lot's of surfaces and crannies this removal is time consuming unless you have a sand blaster that can handle the frame. Also removal of the corrosion between the fractured surfaces.

Next is the actual reconnecting. You'll want to do more then just rebraze the fractured edges together. Some form of reinforcements is a GOOD idea. Whether a couple of small triangular shaped gussets or small cross tubes extra support and brazing surface will go a long way to increase the strength and stiffness of the joints.


Then come clean up. Removal of any brazing flux or burned paint and ending up with shinny bare metal ready for paint.

Next is frame prep. By this I mean the aligning of the rear end and the work needed to have the seat post fit well. How you did the repair and brazing will determine how much of this step you'll have to deal with.

Last is the refinishing/painting. Proper primer, color coat and maybe clear. Rattle can paint will go on quickly and inexpensively but not hold up as well as a two part catalyzed paint shot through a real spray ***.

Of course the taking apart and reassembly of the bike are also part of the process.

Some of these steps are basic elbow grease and some take some skill (with experience) for nice results. Some times a repair person will invite the customer to do as much of the prep and refinishing steps as possible. Other frame repair shops will want to control every step themselves. Andy.
