I've picked up a rather useful skill and finally worked out how to successfully weld/braze Aluminium. Without having to use expensive TIG welding equipment. Joined parts will hold up to about 300-degrees.
This opens up many opportunities to make things in Aluminium for "projects" that you only previously dreamed about.
It will take about 1-hour.
The commercial product is called Durafix and there are some techniques to learn but once you learn the correct way then you will amaze yourself at all the things in Aluminium that you can now join.
If there is any interest, I'd like to hold a workshop to show what's needed, tools and all.
Course cost would be about $10 which will cover the materials that will be provided.
