This may be a little (LOT!!) long, so I will break it up into smaller sections of how this build went together. The sidecar and the bike are old enough now that nobody makes mounts for them. I had to make up my own, using some of the inspiration from how a previous sidecar was mounted to my old '83 Voyager back in the mid-'80's. The Vetter Terraplane is a three point mounting system to allow for on-the-fly lean adjustment for road crown compensation. That works well for lighter-weight bikes, but not for a 960lb Voyager. I decided this rig needed a four-point mounting system. Lean angle will be controlled by an air-shock on the sidecar and an on-board air pump controlled by the pilot. The Terraplane has a roomy trunk behind the seat to carry a compressor, as well as a larger, automotive-sized battery and a heater to blow warm air under the seat and across the floor area. To get started on making the mounts the bike had to be set up at the correct starting lean angle of 2 degrees away from the sidecar (to the left). Fortunately, this bike already has a trailer hitch, so I made up a support bar to bolt to the hitch frame. This bar (see first pic) has two 1/2" all-thread rods with small steel feet that I used to adjust the side-to-side lean of the bike. No center or side stand was used on the bike after the bar was adjusted for correct lean. The bike stayed in this position through the whole process of fabricating the mounts. The next step was to set the sidecar up on a dolly (see second pic)to get the correct fore/aft and side-to-side levels and ride height. I needed the dolly because it would need to be moved close to the bike and away from it often to get in there to work on it and do trial fits of parts. It also allowed me to remove the sidecar's wheel for cleaning and rebuilding without losing the sidecar's positioning.
