New Way Nike Ajax Build, Part 8, Centering Rings

Instructions typically tell you to run a line of glue around the tube, then slide the ring into the glue.

TIP: This is unnecessary and you run the risk of the rings freezing in the wrong position. 

Dry slide the rings in place, then apply a glue fillet to either side of the rings.  

One flat face side of the thick 50/55 centering ring will be visible on the finished model. 

Apply a thin coat of glue on the flat face and let dry. This seals the exposed face. Sand the ring face flat with 400 grit on a block.

Slide the rings into position with the glue sealed, sanded face down. Apply fillets to both sides.

The assembly is glued into the BT-55 with the thicker ring (sanded flat) face even with the tip of the tube.

I used some CWF in the joint between the ring and BT-55,

This was sanded smooth with 400 grit.
