January 31, 201115 yr Tom Colour is not a problem as cases are black anyway, presently repaired with sanitary silicon ! Ross good ole silicon, what ever did we do before it came along?????????? i think that it has knocked gaffer tape off No 1 spot on the bodgers podium. ha ha.
January 31, 201115 yr For what it is worth. If you wish to keep the original castings, then go to a specialist welder who will reset the casing, weld the cracks, clean them up so that you are back to square one(with servicable castings that looked as they did) before the damage. My model 80 suffered similar damage was repaired professionally and looks as good as new! Personally I think that some of the methods avialable, apart from Aluminium welding are just get you home fixes that will fail in use if their life is extended. The choice is yours!

February 1, 201115 yr Have to agree, tig welding is the better option. For a competent welder that is a piece of cake to fix. I've had far worse than that repaired. I tried aluminium solder (lumiweld in my case) I successfully soldered two pieces together quite neatly, the solder ran into the joint beautifully. Let it cool and when I applied the slightest pressure the joint broke. This happened over and over and I gave up. Maybe I wasn't doing it correctly but I can't see any other way of doing it other than heating the workpiece until it is hot enough to melt the solder and then run it into the joint. Unlike weld it doesn't fuse the two pieces together, so I've no idea how it can be stronger than welding, as is claimed. But I'm not a welder or metallurgist so I'm not speaking from authority on the subject. From what I can see in the pictures, what you've done isn't serious and should easily be repairable without splitting the engine
February 13, 201115 yr Author Hi all I tried the repair kit, but using a Propane torch does not generate enough heat to penetrate the joint. My efforts have resulted in a small hole where I broke a piece of caseing off trying to vee out the crack.! Bugger! It will have to go to the welders now, but I strongly advise anybody considering this fix to get an oxy' torch or the heat focus will be too little to overcome the heat sink effect of the rest of the casing. Cheers Mick

Cheers Mick Mick, you made some good points there, maybe wacking the casing in the oven may have helped the heat sink effect. will think twice about using the ally brazing rods anywhere like that, like i said, worked a treat on my tank.
