I think too loose. I should look into the next size larger than 3/16.

A sticky rubber wedge on a stick could potentially do the same thing.
I wonder if an R/C servo and servo tester could be a cheaper alternative to a switch machine (although to be honest, I haven't priced the switch machine used here), using a single tester routed to various servos via selector toggles.
I can vouch for the complication of variable geometry of various brands' couplers, recalling my thread on tuning a Menards 24-flatcar set so their couplers would behave properly.

Tortoise switch machines are $18.95, shipping included. Two diodes and a SPDT toggle switch to control it are about $1.50.
I have a couple trucks that simply don't couple with most of the other couplers. They reside in the junk box. Somehow the actual shape of the coupler body is slightly off. Go figure.
