Bachmann coupler fix

As I said in report No.5, I would post this fix that works for me.

💀Liability/ safety warning. ðŸ‘‰I am not liable for your accidents, damage or misuse during this fix. Tools are sharp and can cut you or other things, 💩, always follow the tools safety instructions first. 👷

Having troubles w/ your Bachmann couplers uncoupling or not letting the pin drop to lock the knuckle?

Yea, there are better couplers for operation and looks, but unless someone wants to buy me 30+ pairs at $10.00 +- a pair... That's another locomotive.

Well this is my fix for those issues.
It is easiest do this w/ the coupler still attached to a truck, but the truck must be removed from the car.
1-Find a piece of 1/8 square wood or plastic to hold the knuckle open as in picture.
2- You will be taking slices off the RED face using a #11 blade in your hobby knife. This RED face is what keeps the pin from dropping until the other knuckle pushes it past the top pin ledge. Thus won't lock or makes pin pop up and uncouple. ✋DON'T START, READ ALL OF #3 FIRST, YES YOU!
Area painted for clarity. Left coupler has plastic pin, right has metal.



RED face you will be slicing a little off.

3-It works best if you push your blade down from the top with the point facing the inner void and the rear of the blade resting on the top of the knuckle. Slide the blade towards the void, slicing the red area about 1/64th. Then use the point to free the red slice where the red face meets the white face. Make sure the face you cut is smooth w/o any burs that can hang up the pin dropping.
WARNING, test before taking another slice, too much will make the knuckle stay open too far and slip apart=uncouple.

4-To test, I have an extra truck w/ coupler that works ok to test the pin drop on ALL cars, I make it so the pin drops with moderate pressure and within a half a second of the test coupler pin drop. Repeat #3 as necessary.
Also, Bachmann couplers have plastic and metal pins. In picture above, left one is plastic, right is metal. The metal ones work better. The plastic have a large hole on side of pin and a seam on very bottom, metal has a very small hole in top of pin, flat on bottom.

Good coupling.🚃🚃
