filling in holes

[timmyfishfinger]

Hope someone can help here. I'm attaching the steering head tubes to my tadpole main booms. I've made the fish mouth cuts on the booms so now have the correct steering angles. Trouble i now have is because i have angled the round tubes and my booms are square, i now have a diamond shaped gap at the bottom.
I know you can plug weld to fill holes, but i cant place anything behind the hole to weld against. Will i have to try and weld a tiny plate over the hole?
Largest gap is probably 5mm. Can i just try and build weld up around the hole?
Cheers Guys.

just build the weld up over the hole

Working on some of my dodgy choppers I got away with packing the holes with offcuts of gas welding rods and even pushing a bolt into the hole and welding over the top. Not orthodox but it looks fine and we have never had a frame fail. I dont know if the senior welding inspector would be too happy about it, but would he spot it?

I just got done filling a bunch of holes in my pickup truck. On most I was able to get a piece of copper behind, but on a couple I couldn't. On these I just hit the edge of the hole and went around until it was filled.
