Thanks Duke!
The glue securing the landing gear legs have been given a couple of days to cure so I can now put the wheels on. Since I have sanded flat spots on the tires to depict weight compressing the rubber, I have to make sure that the tires are rotated to put the flat spots in the right position. A quick-setting two-part epoxy such as JB Kwik Weld works well for situations like this as they give me a 2-5 minutes to make adjustments before the glue starts to harden.
Mixing equal parts of the light and dark colored components yields a dark brown goop with the consistency of toothpaste.
With the wheels attached with JB Kwik Weld, I alternate the model between the jig and a flat tabletop to ensure that the tires' flat spots are in the right place.
And now the model can sit on its own legs for the first time!
I'm gonna have to try this myself.
