Mike would you have any tips for tacking aluminum while holding the work with one hand. I guess where I would be a bit stumped on something like this is without being able to add rod? I guess there is an ideal method for this so you don't just put holes in the work. The next post I make will show progress of what I need to do today on the project and its a 2" x 3/16" plate rim onto the top edge of the 3/8" main frame. It will need to be angled up and holding and tacking would come in handy. As I am not comfortable with the tacking with out using rod I will be making up some sort of a clamping jig I guess so I will post some pics later on if things go good.
