Coolant routing modification

I TIG welded a new piece of aluminium into the hole in the coolant channel. This was my first time TIG-ing Ali and cast ali is the hardest due to all the impurities and the difficulty with the heat conducting away so quick.

 

I'm pretty pleased with the result visually though have no idea how strong it is. It only has to contain the coolant pressure rather than having any real structural significance.
