Each item is designed in Solidworks 3D CAD.  Urethane casting patterns are made using Rapid Prototyping technology.
HO Scale

Detailed draft gear replaces Accurail's hard-to-find #1020 and #1031 parts with one VERY important improvement:  SELF-CENTERING.  (This feature is OPTIONAL ... you can still position couplers where you want by placing the spring inside the coupler's shank.)

No additional drilling required to retrofit these parts to cars already equipped with Accurail's draft gear parts.

Kit includes (4) pairs of color-tinted urethane castings (4 car's worth) and (16) 0-48 x 1/4" self-tapping screws. 
Sergent's ENC87K (narrow shank) coupler and friction spring NOT included.

SUPER-SIMPLE assembly using CA ... just (2) parts for coupler box, (2) "riveted" cover plates, (2) screws plus Sergent's coupler and friction spring.
