    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Broken cooling fin

Hello all,

I'm still working on getting all the parts to my 550/650 project together, but have run into a problem. One of the cooling fins on the bottom of my cylinder head, close to where the head gasket mates up to the jug, has broken. Its not a large piece, but was wondering if any attempt should be made to weld it back.


Thanks,
William
 
If it is not broken through the head I see too many bad things that can happen welding that close to a mating surface and for what benefit?

Pretty much, I thing you'd want to know a guy who was an artist with a TIG welder even if you did consider it.
 
it wont hurt at all. just dress it up with a dremmel type grinder. if you are a perfectionist you could always grind off the same fin on the other side to match
 
If you want it to look original make a fin out of JB weld. It won't do much for cooling but it will look nice. One fin missing won't do squat temperature wise.

Welding it is just to tough. There is an aluminum brazing rod that you can buy that is great to fix these. All you need is to super clean the aluminum and then you need a propane torch.
