The center post is simply a tube with a slot about 3/4" deep cut on
both sides at the top. The handlebars themselves literally just clamp on.
My initial plan was to use a "drag bar" style handlebar.
but have since decided what I would really like to do, and would look
better / more in line with the overall design of the build, is to install
sport bike style handle bars. . . . . . . . . . . . somehow. I have a
9" lathe, a mig welder, a AC/DC stick welder, and a drill press, along with several different bench grinders and side grinders. What I do not have, yet, is a tube bender. :-/
I too have many ideas running around in my head. But am ALWAYS open minded and quick to listen to any other ideas & advice! Life just seems to
go much smoother that way!
Pic 1 is from the Buddy parts book, but is the same handlebar set up. Oh their website they are calling those "drag bars" as well. I just noticed that. --- shrugs --- Whatever it is, I am going to build my own version of them.
Pic 2 is the style I am going for when I get to building it
