Broken Fin

[kdx Geoff]

l have a small piece of fin missing and looking for ideas to make it look right. . Making a piece to fit in seems pretty straight forward but having stay in place......    lm going to paint the engine after the repair.




Thanks

I'd just use devcon, & use plastic or something to shape until it hardens then dress it up with a file, coat of gravy all good.

tig weld a donour peice in  then done and dusted all proper like
looks fresh have ya got the missing bit off the jig saw?

Not a big piece missing from what I can see, build it up with a few beads on the tig & file it back to shape

Yep I would go with that

Thanks blokes

option 1 seems the simple fix

Devcon is probably your simple fix, personally I would weld it but then I'm biased.

The missing piece is irrelevant as it is much easier to fill the cavity than try to hold a small piece in place and get penetration both sides.
I would just pitch the broken piece when you weren't looking and build it up with weld.

Down side is you would need to take the barrel off for welding and for the perfect finish you would want to blast with a course garnet to get the cast texture back before painting as the patch would be smooth after sanding back.

Agree the best way is not allways the easiest

Hi Geoff, sorry I should have read this earlier.  YOu could shape your piece and then some sort of metal glue will work fine. Some years and about 5000 miles back in used adhesive to repair the casting on a Z900 cyl head, tach drive part of the casting was broken off and still bolted to the cable, I just scrubbed it all with white spirits, mixed the adhesive up and put it back on, its still there with the cable running through it and bolted to it, your fin piece will stay for ever.
Just find a damaged barrel of similar metal and remove a piece so looks same, file to shape wack it on my friend. Easy. No load on it at all.

Let me know if you want me to chase up the brand of adhesive, I borrowed it from my local mc shop, Mick Dyers in Penrith, good bloke with a LOT of experience.
