Hi Frank.  Thanks for that.  Im still not sure what i'll do.   I might just put it to the side a little, but we'll see.  Probably do that this weekend.
Regards
James

Hi James. Cutting into the hull weld isn't a problem. Your weld looks good
( so does your web site ) and by using the pre-heat method it will be just
fine.  I would suggest using POST-heat as well. It doesn't take a lot of
time and the  slower cooling prevents cracking where the three different alloys
come  together.
