Came across a picture of a process that I thought might be adaptable for attaching the wooden parts that we need inside our old cars for upholstery and stuff. If it works as well as the picture looks, it should save us a lot of time. Don't have any details yet, all I could find was a picture of the finished results. I'm not sure if the process is adaptable to all types of wood, or just certain ones. Click on the picture for a better view.
Especially good for pressure treated wood it appears. This tune keeps ringing in my ear: Com’on baby light my fire.
You have to use the correct rods for timber welds- there are ones made specifically for hard wood and those for soft wood.
