It's the vertical cylinder for a 900 Monster I have the broken piece and was wondering if anyone knew of any type of high temp super glue or if welding it is possible?
Cheers

You could fashion sort of a repair with JB weld but it would only be cosmetic and not functional. It would also be susceptible to breaking off again. A proficient TIG welder could weld the broken piece back on and that would then be functional. If you have an airport nearby, you could locate a certified airframe welder. If not, a local welder could also do it, but you might end up with an excessively high bead which you would then require some tedious time smoothing.
When I mentioned functional, I was referring to the heat transfer property of the fin. As small as it is, you could also consider smoothing the rough edge and leaving it as is. The effect on the cylinder heat transfer would be infinitesimal.
You could build it up with weld. Another solution is hit it with similar paint and few will notice.

+1.
Or get the piece welded back on and paint it.

Cheers, I work at an airport! I might hassle the engineers with a case of beer under my arm [thumbsup]

There ya go! But forget the engineers. You will get better info from the maintenance techs. Depending on which class airfield it is, there will usually be a FBO weld shop. If there is a flight school there, just ask their maintenance people who do they use for their welding.
Edit: Scratch what I said about engineers. It occurred to me that you might be located in an area which refers to techs as engineers, so I looked at your profile and saw that that was the case.

Correct, I've never really worked out why that is so! But, hey they keep me safe so I'll call them whatever they want me to call them ;)

I have tried that stuff. It works OK. I wouldn't bet the farm on it to hold that cooling fin on though.
easy with a TIG welder Marty. Especially because its the bottom fin.
You'll only be able to weld one side, but with a good weld prep and dressing afterwoods it'll hardly be noticed.
Remove the seals (and probablly the rockers and pins) first so you can give the head a bit of pre-heat...
The middle ones are a bit more tricky...
You do have the piece that broke off eh?
oldndumb.. here in Oz they call them Tech's, fitters, welders, boilermakers and numerous other names. The trade is very broard.
Must be an airport thing for them to be called engineer's Marty?... Engineers usually have a uni degree, and most dont have any hands on experience.
If you get stuck Marty I'll do it for ya if you hassle me with a bottle of bourban under your arm! [thumbsup]

Cheers Monsta [bow_down],
What make of bourbon do you prefer?
It's the top fin and I do have the broken part [thumbsup]
Re: engineers it's an aviation term used in Australia I've never really worked it out! The full title is LAME (Licensed Aeronautical Mechanical Engineer!). I'll PM you my number and work out a time that suits ;D
The repaired cylinder with many thanks and much appreciation to Geoff (a.k.a. Monsta)
The repair was done to the top cylinder, top fin nearest corner - refer photo at start of thread)

(The heads are just spares holding everything together while I fiddle with the original heads)
Mmm nice and clean!
Looks great!
