ES Pipe Repair??

[Ken Velez]

 Hi mark I did it using carbon cloth and CA. The pipe was cracked (split) at the bend not broken, cleaned with alcohol scuffed the area with scotch-brite and repaired. So far so good. Mind you this is a 2 c and I know the exhaust temp is lower than a 4c. I cut a piece about 1 inch wide 6 long tack glued the edge of the cloth and wrap it around 4 times and soaked with CA. Cut off the excess and used a dremel sanding drum to smooth out gently.

  Hmmm.hadn't thought of the Pre-Cleaner.  I have the PPG stuff.  Would you consider "soaking" it?  Cleaning the outside is only part of the challenge since the oil keeps soaking out of the cracked portion.  I was considering either pouring alcohol through it, or completely submerging it, and then blowing air through it to make sure it was all evaporated.    I figure a few .99 bottles of alcohol were a good investment over a new $169 pipe.

   

  Does anyone have any thoughts on the type of resin?  Is temperature a problem, meaning do you have to use a special epoxy to handle the high heat demands?

  I would suggest a two step approach. First, wash it with good strong soap/water....or maybe Simple Green. Then go over it again with Automotive paint "pre-cleaner" from folks like DuPont or PPG. Thoroughly dry. 

  Any of you composites experts got a better idea?

  Cheers,

  Has anyone had any success in repairing the "stinger" on the end of an ES Carbon pipe?  Mine is cracked at the bend and I'm considering trying to fix it with Carbon cloth and epoxy.  Anyone have any experience with this and how I might get all the oil off/out of it before attempting??
