Adam Van Steinburg Posted January 12 Report Share Posted January 12 Hey I have an MKV post in which the lower stage and it's connector to the bottom stage are rotating. It would seem the piece that is inside the post that seeds into the electronics is rotating inside the post and I was wondering if anyone had advice / recommendations for repair? What kind of adhesive is usable? Best ways to get the piece out ect... Thank you. Quote Link to comment Share on other sites More sharing options...

Premium Members Tom Wills Posted January 13 Premium Members Report Share Posted January 13 The epoxy has failed on the joint, and sadly, there were no safety pins in some of these older MK-V posts. This will need to be sent to someone qualified - either MK-V or someone who has experience with carbon fiber bonding techniques. When it’s re-glued, you should ask them to add in safety pins so if the glue should ever fail in the future, the base of the rig won’t drop off. Where are you located?

Premium Members Tom Wills Posted January 13 Premium Members Report Share Posted January 13 I have heard of good results from some of the Scotch Weld adhesives, and I have also used some adhesives from West Systems that have held up well in a post I repaired. I have also heard in some communities like high-end RC aircraft building that people have had success using J-B Weld as an adhesive for bonding aluminum ends to carbon fiber. I can’t attest to any specific adhesives though, as I don’t have any on hand that I can reference. The biggest thing is surface prep - you must get all of the old adhesive and any residues off of both the aluminum end and the inside of the carbon post, without damaging the structure of the carbon fiber tube. Also the mix and curing of the adhesive is crucial - the MK-V post I saw that had failed appeared to have not cured properly. Then addition of the safety pins is huge as well - they provide a physical “key” to ensure that the post end stays in place, and they do require some care and careful tooling choice so as not to split the post when drilling them out. I’m not sure if there’s someone who does maintenance of this sort in the Vancouver area - if you were in the east coast USA I’d offer to take a look at my shop.

Adam Van Steinburg Posted January 13 Author Report Share Posted January 13 Thanks again Tom for offering all this information I'll try and look for some people locally who deal with carbon fiber! Quote Link to comment Share on other sites More sharing options...
