Thank you all for very warm welcome.
Today is the day of my first big milestone - after over 2 months of training I became EU Certified MAG Welder
It's quite important, because, here in Poland, THEY sometimes require attestation that chassis is welded by certified welder. So - I can write one myself
Other thing is that I wanted to learn welding from professionals...
Now - I have to buy welder, steel and start building... and looking for engine donor bike.
