Eric, Any of the Silver solders require too much heat, as does the Hi Force. The only solder you want to use is Brownells Tix Soft Solder. Be very careful with heat, don't try and use anything that builds more heat than a propane torch and you will have the best luck with a tip that gives a "broad" flame as opposed to a "pointed" flame. If you are attaching a top rib use one of the "heat stop" paste compounds on the bottom rib. Keep the heat on the bbls. and let the heated area melt the solder at the juncture. Important, be very careful with the heat. Too much heat will cause the bbls. to swell more than you want and when they cool they will "shrink" where you heated them and cause the tube to be smaller (ID and OD) where you heated it. Just as soon as the solder flows get the heat away. The temperature of the bbls. will continue to rise for a few moments. Don't force cool. Of course there is a lot more than I mentioned depending on wheather just a spot repair or laying the entire rib, methods of holding the rib ect. Hope this is helpful. Regards, John Hancock
