Shelf Type Couplers - Model Railroader Magazine

Hi Chris,

With a sharp hobby knife I trimmed away the Proxabrush plastic handle exposing the wire (as seen in Jeff Johnston's Uncoupling tool Vimeo vid), then cut the wire about 3/8" past the bottom of the bristles.  Wire dia. is .016, drilled the end of a bamboo skewer approx. 1/4" deep with a #75 drill bit.  Liberally coated the wire with super glue gel & shoved it home.  As noted I prefer the 'Ultra Tight' size.

Yep, just push the brush between the knuckles with some spin action (slack at the couplers helps).  I've made maybe a hundred or so uncouples so far, no bristle wear I can see, guessing they'll last a long time.  Lovin' it.

Happy uncoupling,  Peter
