Coach bogies
« on: November 02, 2009, 10:20:22 PM »
For a couple of years now there have been repeated suggestions that the Society should produce a generic carriage bogie sideframe which members could detail as they wish, or encourage the trade to produce the details for different railways and types.

We have taken the first step by having laser cut from 2mm mild steel the outline for a 9ft wheelbase bogie.  It has holes cut for the axle bearings; in the centre for the main stretcher; and also for a tierod.  Separate tierods are included, but they are also 2mm mild steel, so folk may prefer to make their own from thinner material.  Sorry I can't attach a photo but I don't know how to reduce my pictures to the 100kb maximum allowed here.

We welcome any comments, suggestions and indeed orders!  The intention is to add 8ft and 10ft and possibly 8ft 6in versions to the range eventually.  Although intended to be generic, rather than make it incorrect for everything, the 9ft sideframes are actually drawn to an LMS design.

I only collected these first parts from the laser cutters tonight, so not been able to confirm the price with our committee, but they will not be expensive.

Any comments?

As requested....



Weight is not really important -it is the rolling resistance that, (to me), is more critical.

The choice of an LMS bogie may seem strange -but the market is about to be "glutted" so to speak with LMS coaches. GRS are (I believe) about to produce a few and Chris Barron now lists them amoung his plans for sale. So this is a cherry pick moment for their arrival.

However I am more interested in what items I could use this raw generic shape to produce things from. With a little "dremel work" and a bit of appliqued ABS sheet -that could very well become the basis for a B0 power bogie for a diesel or electric. A little saw work and some silver solder and you can turn 3 sideframes into a pair of C0 power bogies... Alternatively they are the basis for the front and/or trailing bogies for a steam loco, (possibly you might need to invert them!)

As shown the central bore hole is for simple compensating, but a swift pass of a milling machine with an end mill will give you the slots for horn guides. Or you could use sandwiches....

The bogie sideframes will eventually be available from the Society Shop, but at the moment they can be ordered from me - address in the Newsletter.

Price £5 per carriage set - i.e. 4 sideframes and 4 tierods.  Postage £2 for any quantity.
