looks like you are making great progress! it is a very tricky metal to weld so when you do master it everything else will be easy some tips I can contribute is aluminum is very finicky to weld especially when welding thick to thin there are some tips to help you with this. first clean alum with a CLEAN STAINLESS BRUSH USED FOR NOTHING ELSE! wipe your filler rods too and do not let them lay around the welding bench to get contaminated with grinding debris. Take G.W.'S advice on balance . I often use a propane torch to pre heat the thicker alum. with a torch to get the molecules moving,keep most of your heat on the thicker piece the heat will automatically wick to the thinner piece.something like one second on your thicker piece 1/2 second on the thinner piece.you will come along in know time you are doing a great job already just keep practicing and you will be laying them down like a pro!
