Hello,
Could someone tell me the reason Kozo uses cast Iron for the brakes? could another material be used? I was thinking something like car brake pads. Does anyone know anybody who uses something else or is cast Iron a must? Thank you.
Regards,
IronMan ;D

I met a fellow who was using automobile brake lining material on his Little Engines 7.5 inch gauge 0-4-0. (Sorry, I can't recall his name.) His opinion was that the brakes were much more effective than plain cast iron brakes. He used some sort of epoxy to bond the linings to the original brake shoes.

Thank you Carl,
Just what I wanted to know, now I can change the way I will do the brakes. I was not sure but I imagined it would work it does on cars! replacement would be easier, less wear on the wheel. When I get there in the project ( soon) I will take some pictures, in case someone else decides to go that way. Once again thank you.
Regards,
IronMan ;D

Remember there is asbestos in brake shoes. And the ones that are asbestos-free are a lot harder and liable to wear your wheels. Cast iron is actually a decent bearing material. You could flame harden the tire of the driver as is often done in prototype practice. Grey iron turns into chilled or white iron if heated to a high enough temperature and allowed to air cool. I think it economic folly to wear out drivers prematurely. I don't know of the practical ramifications of hardening your drivers.

Hello,
My reason for wanting to change the cast iron for the brakes in the first place , was availability of material. Finding the required size may be a bit of trouble, getting it cast would probably be expensive. I was looking for another way of doing it, is there another type of material that could replace the cast Iron? Bronze? babbitt? I am open to suggestion, and ready for experimentations!
Regards,
IronMan

Hi, Would you know the grade of Aluminum ? Is it not too soft? I would of thought that the friction would cause it to stick, and lump up. I will try and do some research on the subject it is becoming more interesting my the post.  Regards, IronMan |

ironman just a thought bronze can be abbrazive if not machined right so it might also were the wheel i am using cast on mine i think as i have steel wheels not cast.the shay isn't that quick anyway.

g'day Phill, So bronze is out of the way, I also have steel wheels, souds like a Stones album Somewhere I have seen someone using cast iron weigths the barrbell type, to make the brakes, So far I have not come across one that would fit within the design by Kozo. HOw are you getting along on your project? Cheers, Ironman |
