I do have several bike/sidecar-specific projects being documented on another forum, but they are a bit heavy into custom fabrication, including sheet metal work, machining, and welding. Years ago, when I had my Spyder connected to my first Voyager, I did an article showing pictures of the build of that cooling/heating system, but got "boo'd" for it not being relevant since it was way too complex for what anybody else would want to do for theirs! Violations of warranties, and some such nonsense, etc! Now I just do my thing, post a few pics and share a brief description of the job and let anybody interested ask questions.
But, when I get it all done I will post here since we do seem to have a few VERY talented owners, and warranties are long past valid! There are already several very cool ideas presented here about such things as air shocks and anti-sway bars between bike and hack. One TP is currently being completely restored just like you are doing, by completely dismantling it and starting from the ground up. Another has been so beautifully modified as to mold the flip-top into the base section leaving no seam at all, and a few other mods as well.
Yep, this is the place for all things TerraPlane, albeit a bit slow in activity usually. I even bought mine through a listing here almost as soon as the seller had stopped typing! It's good to have another owner that is active in building/restoring another TP!
I have a lot of pics of the TP's from other owners, sales listings and websites as well as brochures and info if you would be interested. This site doesn't provide much for presenting so much stuff unless posted a bit at a time, making it hard to find at times. You can email me:
