A great tune-up tool from DCC Concepts!
The bearing reamer set contains two reamers designed to clean up the moulded plastic bearing holes of RTR coaches and wagons and older kits with moulded plastic bearings. Fitting between the bearing sockets in place of the axle finger pressure can be applied to turn the reamer and cut a clean tapered bearing for pin-point axles. This cleans out any accumulated dirt/debris and corrects any faults with the moulded profile.
The reamers can also be used to make the bearing holes deeper, for example to allow standard length axles with recent finer-scale wheels to be fitted to Lima rolling stock and dealing with any 'tight' axles.
