ES Composite Pipe Repair

[Wayne Galligan]

Hopefully Gray Fowler will see this post.  He repaired my pipe by using a
piece of 7/8" aluminum wing tub and used a special high temp epoxy and some
fiberglass.  Has held up well all year.    Had to get it very clean by using solvents like
denatured alcohol and roughing up the aluminum with 80 grit sandpaper.

  I have one of these pipes with a damaged inlet.  I found an aluminum tube that fit inside the inlet almost perfectly and tried to JB weld it in and clamp from the outside.  That lasted about 15-20 flights, and now it leaks like crazy.  Is there any kind of epoxy or other sealant (e.g. high temp silicone) that will hold up better to the heat?  Pipe is used with a YS 140, so it gets pretty hot.  I hate to let this pipe go just yet.  Any help appreciated!  Chuck
