Custom Nomad Build Part 4 Ring & Tube Prep

In Step 4, the large "disks" (5060 Adapter Rings) are glued to the main BT-50 body tube. The outer BT-60 tubes are to be glued on later. Past experience tells me to glue the rings to the outer tubes then glue the two larger tube assemblies over the main tube. I was concerned that any measuring mistake (in gluing the rings to the inside BT-50 first) would make an accurate fit of the larger outside tubes impossible.
You could build this model as in the instructions, but I wanted to get a guaranteed best fit of the parts.

The ring on the right is facing up, the edges are slightly rounded. The ring on the left is facing down, the edges are square. This is from the way the blades hit the card stock when they were die cut.

For the best fit, when gluing the rings on the BT-60 tubes, the square edges should be to the outside.



Before gluing, sand the edges of the BT-60 tubes square.
Here again, most tube ends have a beveled edge from when they were cut. Square them flat for a better gluing surface and fit of the centering rings.
