Welded the surge tank and baffles in today. What a pain in the arse!!
Welding the baffles in didn't go as well as I would have liked and there was some bad language flying round the shed.
When I tried to weld them into the floor of the tank the aluminum moved around a lot. In the end I just welded the baffles on the ends and didn't attach them to the floor of the tank. Had to massage the bottom of the tank a bit to get it back into shape. Just too difficult to weld. I reckon it would have been easier to weld the baffles in before welding the end plates on. Oh well, I know for next time.
I reckon I might have to invest in a straight TIG torch. It's really difficult to weld inside a tank and get into the corners with a conventional 90 degree angled torch.
All that's left to do is weld the lid on, weld the filler neck and breathers in and weld some brackets on the sides.
Cheers
