Probably a daft question. Yeti 575 carbon swingarm decided to part company with the alloy pivot bearing housing. Would something like jb weld or similar do the trick? Out of warranty so a replacement is around 500 sniffs.

Carbon bond to aluminium?

JB weld contains steel so nope. Big risk of galvanic corrosion.
Ideally you want a really good structural epoxy. You could look online for a place selling composite and/or boat building supplies. The wood yard I use sells decent epoxies as they do a lot of marine grade materials. Preparation is key to getting a good bond and you may need to apply heat.
The only thing off the shelf in the local hardware store I would use is blue Araldite but that needs curing at about 50 degC. you could just carefully rig up a hairdrier to gently blow across the area for a couple of hours (don't get it red hot).

That chap who specialises in road bike repairs.. the name currently escapes me.
He fixed a bonded bb shell on a cannondale roadie for an old pal.

^ good call. Should be a pretty straight forward fix for them and not too expensive.

dp420 is a good glue for this but your going to need more than good glue to bond.

dp420 is the stuff we use for bonding carbon tubes to aluminium inserts. As said by compositepro (he knows his stuff!), you need far more than a good glue. Prep is massively important, clean work area, tight fit to minimise gaps, a good key on both surfaces, and more. Would recommend looking into it thoroughly if it's something you undertake yourself, you're going to be riding on it so you want it to be solid. If you don't have the time or inclination to be really thorough, it'd be worth your while sending it to a specialist, or getting a quote to compare with a new swingarm.
