Brakes for 5 inch gauge diesel electric loco

[loco10569]

 Hi, 

I have nearly finished scratch building a 5 inch gauge riding truck, which I intend to use with my diesel/electric loco. I want to install brakes on the truck and would use cast brake blocks on the front set of wheels and a  pair on the rear set of wheels. There are eight wheels on two bogies. The problem I am having is finding any information, dimensions, drawings etc., to help with this, I was going to scratch build them, and I am flexible to the design of them. Any help or assistance as to help with this would be appreciated.

I suppose if you're flexible on the design then you could just sketch something up that suits you and doesn't necessarily relate to anything anyone else has done. As it's a bogie truck you might find using a bowden cable is the best way to accommodate the rotation of the bogie and these could pull from arms off a central pivot which is connected to your brake lever by rod. One thing I would recommend is to consider some adjustment on every part of the mechanism to ensure you get equal braking. Ian

There's a driving truck designed by Doug Hewson with brake linkages to two swiveling bogies. It has been serialised in Engineering In Miniature at least once and I think the drawings are available commercially though I'm not sure who from.

Thanks for your help, I will have a look for the article in EIM. mike
