The work begins... really really slowly and annoyingly. The Metro metal isn't exactly thick to begin with. Add some rust and it really becomes paper thin. This can be extremely annoying even when the welder is turned all the way down as you still burn through. Add tons of spatter from the remaining rust and arrrgh.
Anyway, I shall now share pics now that I'm done venting!
This is the first patch I did. I needed to cut the hole bigger, still battling too much rust.
All welded in, messy but solid. I'll be priming this before welding up the next section/layer.
Here is the next area to tackle. As you can see I kind of went a bit more crazy with the angle grinder, I'm sick of welding to rusty metal!
While looking at that area, I poked around a bit more, removed the plastic wheel liner and found this.
Then I literally poked it... a lot, and did this.
Darn you Metro designers and your lack of designing for salty environments!
Ah well, brakes over, time to go back to work.
