Tom, I'm going to restate the obvious but when builders say "more heat" we are talking about volume. The torch tip has to have big enough holes to put out a decent sized flame. The Paige tips were designed for the jeweler trade brazing small items. The G-tec company makes tips for the general industry that requires more BTUs. So if you are going to start the process of brass brazing forks you need the right equipment to do it properly. The multi-port G-tec TEN #3 is a good place to start. An alternative is a Victor #4 TEN tip - which is a single orifice recessed tip. Victor tips are really expensive so the G-tec is probably less expensive than the Victor. Yes a Victor or clone #3 TEN tip will braze your sleeves. The smaller the tip size the more pressure on the brazer to have a better more precise pattern. One of the most common beginner mistakes is to not move their flame evenly over their work. A similar example would be like painting a wall and putting too many coats some places and not enough other places and still getting paint on the ceiling and floor. A bigger tip held further away works better for the learner. This kind of soaking heat put less pressure on brazing with a precise flame pattern.
