Our extra large 3D printed bell mouth couplers are suitable for use on our 7/8 scale wagon kits and are included as standard in the 7/8 Trefor Quarry wagon kits. These home builder packs include a pair of buffers ; two “T pins”; a link bar and 4 self tapping screws. I.e. enough for one wagon.
They are based on “Bell Mouth” couplers as supplied by the likes of Hudsons of Leeds; Orenstein & Koppel and Decauville. As in the prototype, the modeller couples the wagons by first inserting a “link bar” into one coupler mouth and dropping a “T pin” down through a hole in the body to trap the link. The link bar is then inserted into the bell mouth on the next wagon and the other link pin is inserted. This allows the wagon to be both pushed and pulled round tight bends.
To provide compatibility with other makes of coupler; the new Bole Laser Craft coupler may be connecting with a traditional three link chain looped over the top of the “T pin”.
The couplers are made from Selective Laser Sintered nylon with an attractive “charcoal black” finish. An engineering grade nylon is used to give a tough and compact coupler.
The couplers are simply screwed to your buffer beam with the supplied No 2 (i.e. very small) self-tapping screws. Alternatively if you are a “hex head fan” they can be bolted on with 8BA nuts and bolts (not supplied).
