In my typical running before I can walk style I am now thinking about fabricating an aluminium seatbelt tower brace for my mx5 (which I am now balls deep in the prepping stages for the sill resto) as a side project out of some tube sections and plate that I have recently acquired.
Main concerns are whether I will be able to get the aluminium wire through my machine without a spool gun but I realise as noone else has the same machine I am on my own there!
Mostly I am asking whether I should be bothering with this at all using a hobby MIG or whether to put the project on layaway for when I eventually buy a TIG machine? I guess the cost of consumables for such a simple project may outweigh the benefits.
Also thinking about galvanic corrosion - How much of a coating is going to be 'enough' as this thing will be bolted down to fairly thinly coated steel and is often going to be out in the open air.
Lastly am I right in thinking the polarity needs to be flipped to do ally with a MIG or am I making that up?
