New Way Blade Runner, Part 2, Engine Mount

The 20/50 centering rings are laser cut from plywood.

I like to sand off the charring from the faces using 400 grit on a block. 

It's not necessary to do this, I want cleaner parts - especially when the surfaces can be seen on the finished model.

The motor mount tube is marked 1/2" from both ends for centering ring positions.

Slot the tube for the engine hook at 1/4" from the top and insert the upper bend of the hook.

The retainer ring ends up centered between the centering rings. Slide on, apply a ring of glue and into position. 

The fit of the rings was almost perfect! A hair tight.

For a smooth slide over the ends of the tube, a piece of 400 grit was wrapped around a finger and used to lightly "ream" the center hole.
