If it doesnt work google this.
How to create accurate weld effects by Lee Lioyd.
Its on the Armorama webb site.
I printed it off for myself its great
He uses a cut off tube tool which does both covex and concave welds.
For concave welds I have been using different size paper clips.
I am still learning but I think the most important part is the edges of the weld,try
and get it as smooth and flush as possible to the surface,so no gaps underneith when it
drys,bt using a damp cloth or (lick your finger).
Deffinately worth looking for this.
Cheers
Phil
