That work thing gets worse when you retire, folks tend to think that since you are retired that you can start doing some of there work, since you have so much free time on your hands, be careful who you tell that your retired!
We have a (JD Squared) bender that we modified and with a hydraulic power unit, we designed stop gauges that we can change quickly and help us repeat the same bend multiple times, we use 1½" x 11ga tubing for most all of our parts, this keeps things a simple as we can make it.
Were just little guys but we use factory production methods when we can, since this retirement project has turned into a full time job, unfortunately!
I do think that yours will still be titled as a trike, but around here they call them a reverse trike.
I wanted to convert my road king to a double trike, or a four wheeler might be a better name. I thought it would be a cool project but someone offered me more for it than I thought it was worth so it left.
A reverse gold wing trike would be a nice ride!
