Engines / Pro cast iron repair
« on: August 21, 2006, 02:23:11 AM »
Had a long chat with an experienced engineer friend of mine today, and amongst other things we discussed repair of cast iron. He said that if strengh is not critical, but a reliable long last repair is, that its always better to braze rather than weld.

The main reason for is apparently there is far less chance of the repair cracking as it cools or failing in service. Found an excellent web page that explains all of this in an easy to understand way, and this looks to me an ideal way of making good broken or damaged cast parts belonging to a Lister engine.

Anyone ever heard of "Powder Welding"? This uses a nickel powder, and a special oxy-acetlylene torch, and seems ideal for effecting low temperature repairs on cast iron. Heard of the process from a friend of mine who worked for many years in a railway engeering workshop, where they used the process for rebuilding worn train wheels.

Engines / CS 6/1 repair?
« on: August 20, 2006, 11:52:16 AM »
Just found this forum, and wonder if anyone can advise if its possible to repair a cracked cylinder block on Lister CS 6/1? Been told by an engineer I know that it may be possible to braze this, but wonder if there is any other way to do it as I have no access to brazing equipment.

TIA

Bill
