no experience/tools. what to use for very small brazing job

[Dr Page]

As the title says, this will be my first and probably last brazing job. I'm not looking to set up a permanent job or spend more than a few hundred dollars on equipment.

I'll start by saying I love my guns. What I'm doing is modifying the rear of a beretta 92 frame to have a curved beavertail (the little 'teat' just below the hammer, above the grip), similar to a drop-in safety for a 1911. This is a cosmetic change only. I say it again COSMETIC CHANGE ONLY. I am not tampering with the function of the gun, so I don't need any lip from any Safety Sally. All I am doing is filing away about 1/16" of the very rear of the gun frame. Then I am crafting a curved piece from 6061 T6 aluminum to look like the curve of a drop-in safety. If you google a 92fs and 1911 drop in safety and compare the two, you see what I am getting at.

EDIT: ADDED PHOTOS TO ORIGINAL POST

It's just a simple curve that tapers to a soft point. I have several spare gun frames with which to practice on before I finalize the real deal, but I need to know what sort of equipment (torch, etc) is best for brazing aluminum to aluminum (the gun's frame is aluminum). I want some input from some experts on what I need to buy this project. I plan on practicing some basic brazing, sticking piece A to piece B. After that I wanted to practice on a couple of spare gun frames I have lying around. So what should I buy to last me basically a couple dozen uses?
