Your success is most likely due to your aluminum welding skills.
I have none... My welding buddy does not weld aluminum very well but he tries  :-)
This may be over kill... then again maybe not... My adapter is only 1/4" thick...
I'm sure Larry, Motorrad, or some of the others here could do it but I have to make due with what I have to work with.
I even thought about using my clutch cover as the fixture but decided it wouldn't be stable enough... Again, I'm sure this is over kill but I want to give this project every chance of success.
I have 3 clutch covers that need to be fixed, I'd like to be set and ready to go from the very first try.
Who knows, perhaps I'll offer a finished product if I get good enough so as to bring down the cost  :-o

I had a friend weld for me. Maybe a bad case half would be good to secure to while welding. I have one but did not think to use it. Thanks for the great parts.

I have a set of junk case halves if they are needed. I just keep them around for frame mockups.

Found this cover https://picasaweb.google.com/102067261144953476086/ClutchCovers#5989268830144816242

(Still try to find how to post pics from picasa.)

It's From Paul Malins KX500SR in 1991. It has "the" elbow of the cylinder on the water pipe wich than runs to the rear of the cylinder.
Does anybody knows wich cover this could be?

Here is the test adapter bolted to the jig as it is back from surface grind to make sure it's flat.



Here we are ready for weld.

How will he get better if I don't let him poop on my parts once in a while?

That seagull should practice on some scrap aluminum not on your clutch cover lol

Cast aluminum stuff is always iffy, particularly when it has been soaking in oil. Or anything really. Salt water is ugly too with salt crystals imbedded in it. He needs to practice on old crappy cast, not just practice!
Just got my old 1967 Miller 320 AB/P going again Saturday. I lost the HiFreq a while back. Thought it was one thing but turned out to be another. Just glad to get it going again for a couple hundred. Was thinking for a bit that I would have to bag it and either buy another AC Tig or just pay someone to do my stuff.  :x  New inverter ones have some great features and do not weigh much compared to my beast at about 1000 LBS. would clear out a little shop space as well but then again, I own this one.  :-)

for welding it has to be metallic clean. any little oildrop is not good in the welding area  and also important, the right heat treatment before and after welding...

letīs wait, what you finally get back from the welder...   :wink:  ...

blast the case bare with glass, then soda, then bake it on a 10$ walmart hot plate until it smokes out all the crud from the bolt holes. weld it while its hot.  :wink:
