Er... how do I mount my bogies on my Worsley Works Darjeeling coaches?
I'm presented with a smooth floor and bogies with a hole. I suppose I need a rod and packing washers... clearly I don't know how to move forward.
Here is the kit:

I searched for 'bogie' on this forum and learned quite a lot including a reference to dressmaking press studs but I'm still intimidated.

You need to drill holes in the floor to match the bogie centres, then you solder a 10BA nut to the topside of the floor over the predrilled hole. Fix the bogies in place using a quarter inch 10BA screw. using 10BA washers to ensure a smooth bogie swing.
With the Worsley works kits that are based on the 3mm scale and Comet coach kit way of doing things they use a small dressmakers press stud as the pivot mechanism. One half of the stud (generally the female half) is soldered to the underside of the coach aligned with the bogie center (there is usually a small etched hole in the floor / chassis to mark these) with the male half of the press stud soldered to the top of the bogie, again aligned with the pivot center. It can be a bit hit and miss aligning the halves of the stud with the pivot center and some people have problems where the stud is not sufficiently flexible to allow the bogie to rotate.
As Garry has suggested one can use a nut and screw (it looks like a bolt but is correctly called a screw) as a bogie pivot. Again one needs to be careful with the alignment of the pivot holes and it is useful to have drills the right size to match the size of screw used. Each screw size will have two different hole sizes associated with it - a 'clearance' hole will allow the screw to pass through the hole whereas a 'tapping' hole will be slightly smaller to allow a thread to be cut that matches the screw (essentially making the hole just like a nut). The brass screw is unlikely to cut a thread in the brass coach floor (it would in plastic) so you would need another hand tool (called a tap) but the thin brass floor is unlikely to be enough to hold the screw so you'll still need to solder on a nut, and in which case you'll need a clearance hole in the floor anyway! The exact size of the holes is dependent on the size of screw - a google search should bring up tables of tapping & clearance holes for the various sizes.
Thank you both very much!
