That email address is linked to a business, and is commonly used by any of the 4 people connected to the business in regard to posting on the net, membership of various forums etc.

FYI "Guy Fawkes" or John Bunt I am told is a workshy single man from Exeter in the UK, who last year alleged that being trolled on an obscure Usenet forum, had resulted in his becoming impotent;  in response to which he took legal action against 3 ISP's and 3 individuals, which  as you can probably guess from the content of his posts on here ended in abject failure, and unpaid legal bills of $71,617!

Personally though I have little interest in ridiculous idiots like Mr Bunt, but had posted here solely looking for help with my engine, which as soon as I have repaired the cylinder and got it looking good, is something I want to take around UK shows and rallies along with my small collection of classic motorcycles.

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.

The method I have been told about is termed "Micro fusion welding" and apparently is very suitable for repair of cast iron parts, and is done with an oxy actylene type torch.

Apparently the "repair" carried out by Guy Fawkes, may well have been 100% sucessful if it had been in a low stress situation, ideally under compression loading. However the fact that its not, and bearing in mind the area of welded material between the cast iron and mild steel MIG weld is going to be glass hard Martensite, then its almost certain that the repair is going to fail pretty quickly.

The proper way to effect a repair such as this would be with braze, or ideally powder welding. A friend of mine who is now an engineer in the UK nuclear industry, has provided me with this information, and to tell you the truth after having a quick read through some of the stuff on Guy Fawkes web site, it seems to me he doesnt really know what he is talking about.

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.

I am not "Chris Stevens", this being the case I wonder if you would be able to provide advice on how to go about repairing my engine, in the same way as you have done yours? I would advise you to get things sorted out regarding all this legal stuff, as its very easy to spend a great deal of money and achieve very little.

Thanks for your advice Hoteater.............was told something along very similiar lines by an engineer friend of mine. Have you any further details regarding the new cylinders you mentioned? As to fighting thats not something that interests me in the slightest, and I will ignore any further comments from "Guy Fawkes" as he does seem to be a bit of a troublemaker.

Thanks

I didnt think I had broken any forum rules, by asking a question on here. Shame you seem to have me confused with someone else, as the repair job you have done on your engine looks first rate, and I would have liked to get some advice from you regards doing mine.

Jesus............all I asked for was some advice on repairing my engine! Not got a clue what "Guy Fawkes" is on about, but having had a quick read of his web pages, it seems like he has lost some sort of legal action to the person he is attacking.

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
