This is my first post on BikeForums, but have been getting great info for a long time now. So much so that I have yet to create a thread.
Anyways, my question regards making a tandem into a cargo bike. I've inherited a Schwinn Twinn Deluxe, and me and my wife do not enjoy tandem riding very much, but thats another story. So I want to fix it up and make it into a gear hauler for picnics/camping/etc. My question is, can I remove the rear seat post and seat stays to make more room for a good cargo platform? Will the frame remain safe? I have very minimal welding skill, but am able to patch up gaps left from removing tubes. I also have a cheap powdercoat guy, and will have the paint redone after modifications are made.
I've photoshopped a picture of someone else's twinn to illustrate my idea:
