CF Pipe Repair
« on: May 13, 2011, 04:39:23 PM »
Got a new CF pipe for the PA .75. When I pulled it out of the box, a chip of epoxy fell out of the fillet from the aluminum/CF joint. <See Picture> 

Plan is to fix this myself with regular JB Weld, i.e., not the "quick" version. Is there any prep I need to do on the surfaces, prior to mixing up the JB Weld?   ??? Steve

Hi Steve

Just clean it with acetone then scuff it and use the JB weld, If you like you can cut up tiny pieces of CF and mix in the JB Weld, or you can just leave it alone, I only put the epoxy lip there as a double seal, It will make no differance in the way it performs or the way it runs or last, The epoxy is full strenght in the inside of the al cone, all along the entire al. and CF.
I have never seen a piece break like that, It must have taken a huge hit to that part of the pipe.

Regards
Randy

Cool. I can do that.

Like I said, it came out of the box like that. Maybe a cardboard tube would protect them better. I opened it right here by the computer, and the chip fell out on the phone table. I noticed the chip on the table and wondered what the dickens that was. I'm sure it's a rare thing & don't mean to embarrass Randy at all, but thought a little info on pipe repair might be a good thing, in any case.   H^^ Steve
