| Post subject: | Brake shoes |
Hello, What are we doing about obtaining the old style locomotive brake shoes? These are the type that have a large flat hook at the top and a hole near the bottom for a countersunk cast iron piece that is secured with a flat sheet metal key. Driver diameter is 51" on two engines and 68" on another. Years ago I modified the brake heads on an engine by welding on a curved steel plate so standard "flanged style" diesel shoes (A-28's) would fit on drivers worn down to 41". Any suggestions?

NN must have a pattern somewhere for getting new ones cast - maybe at the foundry they bought from? dave irondave@bellsouth.net |

Contact Lanam Foundry in WV. The have experience providing castings for the tourist railroad/museum industry, virtually any style brake shoe included. He even had an original style brake shoe for my 1937 davanport loco. 304-455-1630 jasonsobczynski@yahoo.com |

> Hello, > What are we doing about obtaining the old > style locomotive brake shoes? We have bit the bullet and are making our own foundry patterns for brake shoes that are a specialty size or design. We prefer to use the style with the steel backer plate embedded in the cast shoe and this is often not available from a local foundry. It can require special considerations at the pattern stage, and some proprietary know how for the foundry. There is also the question of the alloy and hardness of the shoe; you do not want generic grey iron, unless the loco is stuffed and mounted and you only want to fill up the space. We usually use C12 alloy, targeting for a hardness of 280 B plus or minus. Using info from this board, we did call Western Foundry in Colorado, but they could not make a shoe with the backer plate, and disavowed any experience with operating shoes, and would not want any responsibility if the shoes were to be used in an operating piece of equipment. Takeaway - do your homework. Also, Baltimore Casting has closed for business. Bob Kutella 68trolley@comcast.net |

It seems that most of the foundries are no longer making brake shoes because of liability concerns. Is this what you have found? |

We were dealing directly with the plant manager in April when he announced the factory was closing and subsequent calls to him went unanswered. I am sure there is remaining inventory that is in the distribution chain and still being sold, but in our case, we were pursuing a special run of a rare and obscure design from our own patterns. For more or less standard AAR design shoes in stock, try the USA agent for the Mexican foundry, AIRTEK of Irwin, PA. And the foundry in Mexico has been very competent and co-operative in doing the special small run of 32 shoes for our group. It seems to be a fairly modern and up to date facility and is run by a grauate M.E. This is not a backwater operation. I know for a fact that the B&LE RR was using them as a supplier, just before the effective date of the CN takeover. Bob Kutella 68trolley@comcast.net |

Try Uhrich Locomotive Works in Strasburg, Colorado. They cast the brake shoes for our Birney streetcar here in Fort Collins. Our shoes do have cast in safety backs. Though we did make and use our own patterns Uhrich does have a large selection of patterns avaliable. Roger Mitchell Master Mechanic: Fort Collins Municipal Railway n0mcr@netzero.net |
