Re: Frame Building questions
I did not read all of the posts so this was probably said already........wait for it............TIG! I do not have a motorized bike yet as I am here doing research on building one. But I am a former welder (Navy and civilian for a few years, even had a lot of certs). Tig( if done properly and with patience) is your purist and strongest weld. Also perfect for steel and aluminum frames due to thinner metals. And actually quite easy and relaxing once you get the knack. Quite a bit like oxy-acetylene welding. Just a little more high tech. Have fun and good luck!
And now my information search continues!
