Glueing stuffing tube. Epoxy or jb weld?

[Heaving Earth]

What I've been doing lately to thicken my mixture and keep it from running, is taking strands of carbon fiber cloth and cutting it into tiny pieces and mixing it in. It does a nice job and I think it adds strenth. I use half hour epoxy when I glue stuff in. It seems a bit more flexable than finishing resin which is super brittle

+1 on this method, I use West System heavy FG filler to strenghen, but I have always wanted to do it your way, how hard is it to cut them into tiny pieces? I am a little clumsy and was worried that it will be a mess.
I also found out that Finishing Resin is really brittle.

I have big plastic container of milled fiber. I use that for filler more than anything.

Be cool if they made milled carbon fiber.
Anyhow, Tim, I just pull out a lock of the strands and cut off 2-3mm at a time with some scissors into a plastic cup I'm mixing in. Doesn't take much to thicken the epoxy with it

I don't know what it was for but I found two quarts of graphite powder in the basement of a jobsite I was surveying. Graphite is basically carbon fiber powder.

Thanks, man, I will def follow and try!

I would encourage anyone who is currently using or is debating the use of a HIGH grade waterproof marine epoxy to take a look at the West Systems web site. They offer tons of advice, products, and information. This stuff is really purpose made for boat/marine construction and repair. Most, if not all, situations we encounter with RC boats can be traced back to the same situations with our full size counterparts. In addition to the how to’s on the web site they list all of their different fillers and there designed application.

Back on the topic; I have noticed that many in the FE world use a ring or a dam system to hold their stuffing tubes in place. This system requires a huge amount of epoxy in volume compared to the ACTUAL surface area that is holding in the stuffing tube in. My preference is to use 2-3 layers of 1oz-2oz fiber glass cloth to hold the tube in. By doing this you’re using a minimal amount of epoxy and your also letting the fiber glass spread out any loads the stuffing tube is seeing. Most importantly you’re saving weight. I will try and get a few pictures the stuffing tube installs on my hulls.

Seems like a lot of guys are NOT using a sleeve thur the hull and Goop to seal the stuffing tube.

Yep...glass cloth on my tubes...

I sleeve all my boats now, it makes life a lot easier.

Nice work guys! that's what I am talking about. I will still try and get a picture of my "sleeve" set up.
