Thank you.
Thank you. I lift the bike on a bike jack to just over the maximum height of the stand (16"), slide the stand under the bike's bottom rails and around the jack (opposite to the jack handle side), lower the bike onto the stand, then roll the jack away.
The attached picture shows the relationship between jack and stand at an earlier stage when I realized a fundamental design mistake: I constructed the stand so that it spanned the maximum length of bike frame rails (front-back), but the stand legs still weren't wide enough to allow ingress and clearance of jack wheels.

My kludge of a workaround is now evident in the doubling-widening of the final stand legs.
