I was given a high-quality US-made jack and matching roller (probably for Harleys) to roll my 2014 Cal 1400 around my cramped garage. The bottom of the bike frame goes from horizontal to angled (toward the swingarm) and, because the bike seems rear-heavy (maybe it's the panniers and top case), there's nothing under the angled part to meet the jack or roller. Jacking the bike under the frame as close to the rear as I could still left the rear wheel on the ground. My idea was to build a temporary cradle and mount it under the frame to "extend" the horizontal area of the frame so I could move the jack and roller toward the rear where I needed them for balance and to raise the rear wheel. I made a cradle out of 1-1/4" drilled steel tubing and 1/4" flat stock and bolted it together with Grade 8 bolts. I had to notch and brace the cradle on the shifter side to clear welds on the frame. The cradle has 2 cross braces to secure the sections at proper distances. The upper arms are a slip fit over the rectangular cross-piece on the swingarm frame (clearing vital parts), and the front ends of the cradle bolt to U-nuts I set on the handy holes on the bike frame near the crash bar bolts. Now that I've built it, the big question is, would I damage my bike by lifting it with the swing arm and the frame bearing the weight? Not worth trying if damage is possible . Thank you all in advance.
