Re: welding fins
Tig one layer on top of the last, then grind and file to shape, then blast with steel shot. Trying to fit pieces and weld them into place never gives as good results. The 741 heads are a particularly hard alloy to weld. I don't know anyone to recommend any more, they have all either died or quit.

I just returned home from a 2 week trip in New Mexico, have a few good pix, can't wait to share my off-highway traveling. Got to put 1400 miles on the scoot.

Re: welding fins
Good advice from Dave about building out a layer at a time.
And files work well on alum if no room for a disc or wheel.
I've used a thin cut off wheel for tight places, but I was being careful to not put much pressure on it. They come apart real easy.
See if you can find out the alloy of the fins.
Electrode manufacturers can advise on which electrode is best to use.
Or find someone who did it before, and ask which electrode they used.
If you do find out, maybe post it here?
