I recently decided that I needed a recumbent to make my life complete. Then I looked at my checkbook. I have found several good site on building your own. Signed up for a welding class at my local Jr. College. Both of my donor bikes have lugged frames. Can I remove the tubing from the lugs? I want to do this because one piece of tubing will look neater and more professional than splicing the tubes as in most of the sites I have looked at.
