I have a comp tip that has some definate wobble in it. It has the bolts on the side (older style) bit is a newer comp tip that I had to shorten at the top.

What is the best way to get the tip resealed and firm in the aluminum mast?

Thanks

That's what he meant. We use West Systems when Hobie forgets to send us their stuff.

A torch with MAPP gas will help loosen up the epoxy.

All of those guys above are right. Do exactly what they said, and add an adhesive filler to the epoxy so it has some bulk when you reset the comptip. I find that with West Systems the 404 filler works well. With Fiberglass Hawaii use the glass bubbles. Mix it like a thin milkshake. I find that with straight epo it runs, and if there is a big gap it won't bond well. Also with the torch, epoxy will start to come loose at around 140F, the comptip is a heat cured epoxy (I think it cures around 200F), but be careful to not melt the comptip. Have fun!

What Jeremy said - filler and all. But we say "Mix it till it looks like warm peanut butter." :wink:

The epoxy is not the seal. The seal is epoxy (A&B) foam poured in after the mast is together. If you haven't worked with epoxy foam, it is heat, humidity, and mixing time sensitive, and can/will make a mess. Done right it will seal the lower portion of the mast well.
