Well not exactly but its 3:30am and I couldn't sleep.

Been thinking about a weld technique that might work well with long straight beads.
I like the way you can push a lot of aluminum filler in for a nice raised bead.

I have been wondering if it would be possible to feel the bead with the cup each time the cup slides over it add another bead and so forth.

Maybe somebody has tried it. I think if you could feel each bead as you go over it then you could use it as a gage for spacing on the next and be able to make long runs with the exact same spacing.

It would make a Purdy weld if they are the same to the eye. I know practice can put us close but I never tried to feel my way along with the cup.

I'll try one day when I think of it out in the shop, any of you know of such a thing?
