Might try stretching the beads too. The beaded valleys need to stretch in relation to the surrounding areas as well, or they will just stay shrunk while everything around them grows.
ive always pushed my panels into shape/position before welding. next time build a T with 2x2 lumber (or 2 or 3 of them) and jerry rig a place for them to stand and hold the roof/panel up & in shape..then tack a bunch of spaced spot tacks. the closer you are to the final panel when you weld patches the better as it will kee you from making a patch just a little long or short by mistake or miscalculation. ive spent hours shimming curves with long wedges till almost perfect. sure helps sleeping at night
I had read some metal shapers will planish a tig weld before grinding it, but you’re the second person to point that out. I will give that a go, thanks.
Shrinking typically occurs closest to the weld. A light grind to create a uniform and flat but not flush surface allows planishing to force the metal down and therefore outward reversing the shrinking of that metal. Once that's done then grind flush and work the metal as needed whether with a planishing hammer, slapper and dolly or an English wheel.
you are doing it backwards. You have to first give it a crown before planishing. After you raise the roof you will have an upset and hopefully planishing will shrink it. You welds look bad and you used too much heat. On a long seam you need to alternate from the inside to the outside to balance your thermal input. You are fired.
I’m fired from doing something to try and learn? I may have made mistakes, but that how one learns without a teacher. At least I’m trying. Despite your rather rude comment, I do appreciate your criticism, as it sounds like you have experience in this field, and I am always looking to learn, so thank you sir.
Glad I found this...subbed!! I've been wanting to make mine for a long time.
Good luck! It’s a great tool to have
Love the ingenuity. I'm about to start on my own DIY hammer. Thanks for the tips!

Exactly what happened, live and learn! Thanks for the tip 👍
Looking good!

Why don’t you grind the weld smooth? I’ve never seen anyone try to metal finish with a weld bead proud of the surface

Coming along 👌
Where did you get your lower dies set
eBay
It's not going to move the way you want it to with all that weld bead. Now all the metal around the bead is streaching but not the weld it's self.
That is exactly what happened lol. Oh well that’s how one learns. Appreciate your advice 👍

You'll figure it out, keep working
