Hi there All,
If I wanted to produce a handful of bogies (still haven't quite settled upon 3.5" or 5" gauge yet) to go on some coaches behind Maisie - are there any suggestions as to what is the best way to go.
Reeves do castings for there design, as do GLR and The Engineering Emporium, and there have been various designs over the years - does anyone have any suggestions?
Just to set the scene slightly, I have turning, drilling and milling facilities, but the milling is restricted to light duty (ie I wouldn't want to be hollowing out bar framed bogies from 1/2" thick steel plate) and I have no access to heavy duty welding facilities either.
Yours,
Rich.
PS New forum looks good Andy - all this effort is very much appreciated.

Are you talking about coaches or riding trolleys. Because the designs you mentioned are all for riding trolleys rather than coaches and would look totally out of place under a coach.

Hi George,
I think that much as I would like to have some GNR style coaches (fitted with suitable bogies), this wouldn't be practical for my purposes (especially as I will probably be operating on raised track).
So I guess I'm looking at riding trolleys.
Yours,
Rich.

I rather suspected that might be the situation. Its just that I am designing some bogies for a 5" gauge coach to stand behing my Terrier loco. The making of those involve something similar to the main frames for a loco, ie 1/8 thick for the frames.

On the basis that a 3-leg stool is always stable has anyone come up with a bogey design using 3 wheels. If a biased pair are tied in a 2x3 arrangement this should give a 6-wheel bogey with perfect rail contact.
Might sound daft but ----

I have not seen the arrangement of 3 wheels. One of the members of our club swears for his 2 axle loco’s by one normal “rigid” axle for the cranks and a second which is guided by horns to keep it in place but swivelling along the centre of the axle. In a way providing a 3 point suspension. Must say it keeps to the track very nicely. On the topic of trolleys. There is a picture on my page under the heading of discussion group of my driving car. This using the self aligning wheel sets and has 3 axles. It rides a bit like an car with a separate body and frame. All over the place but boy what a comfort.

In the past I have supplied 5" bogie kits from Australia. They come complete with all parts. Machining is required (manily the wheels) and the sides are aluminimum castings. Whilst it may seem daft importing from Australia, their manufacturing costs are cheaper and overall, even with shipping and import duty, they are good value. Should I make some enquiries as to current prices (I last imported some 18 months ago)? Cheers Peter I shoudl add that this is the same source that I supply the 7.25" Queensland bogies from.

Hi Peter,
Sorry it's taken me so long to reply. I had a look at your web site - the 7.25" gauge versions look good - are the 5" gauge versions similar? Would they be a similar cost?
Yours,
Rich.

If you are looking for a real simple and down to earth design. I say a real down to earth and simple design at the last steam day in Den Haag. The bogie side consisted of a simple U channel on its side. The two sides joined by a simple plate at the centre to take the swivelling bolt. At the location of the axles there were two bolts which guided commercial bearing blocks up and down. This motion controlled by springs. Since the bearing blocks had self aligning bearings there was no problem to keep them in line even as the axle tilted relative to the bogie frame. Looked a bit make do but worked nicely. The wagon was 71/4” and could take quite a load of passengers. The outside could be made to look more “model” by adding some moulded details to represent the real motion works of a bogie. I will have a look at the pictures I took there to see if there is one which shows the bogie. Regards Wilfried Vermeiren users.skynet.be/modelbouw.wilfried |
