Arrow Pinhole in LIM, is it worth fixing?

Ok heres the deal. I am going 6 port turbo with my new fc. I was just finishing up the new 5/6 port holes i grinded out of the LIM. I went just a tad to far and created a tiny pin hole through the side of the runner. Would it be worth it to weld over the hole from the outside and grind it down or should I just use a different LIM. I really am trying to avoid starting this all over again if possible.

What do you guys think?

Weld or braze the hole. Brazing would be the best DIY option if you can't find someone to TIG it. All you need are aluminum brazing rods, a propane torch and a bottle of mapp gas.

I tried that stuff at a swap meet and was impressed.

My friend has a TIG I just wasn't sure if that would work. I took it over there and he said it wont be a problem. Thanks for the replies.
