Hi,

What is a good glue to use to attach plastic parts to bare fiberglass?
This is to secure some cable clamps to the inside of a fiberglass
glider. I'd rather buy a tube than a can...

Thanks,
Boris

Epoxy, or CA aka superglue. If using CA don't use the Superglue from
the supermarket, or the hardware store. Go to a hobby shop and buy two
ounces of thick CA glue and a small bottle of kicker. Clean the parts
apply the glue and hold in place, if it does not set up in 30 seconds
or so then spray the kicker.

Just buy the self adhesive plastic cable clamps from Panduit or Clip Bond.

Both are used widely in aircraft applications. I have used them in many
applications and they are still there years later.

I don't know about the ClickBond ones, but I have used the self-adesive
cable clamps that have the double-sticky foam tape on them. My
experience is that they consistently last only about four years of
service when applied to a painted surface that has been scuffed with
scotch-brite for better tooth adhesion. On unmolded fiberglass, they
only last about a year.

On fiberglass, I'd tend to suggest using small fiberglass cloth patches
to secure slit or drilled aluminum squares to which you can ie-wrap or
clamp the wires or whatever.

It'd be nice if glider manufacturers would build a fiberglass service
corridor into their fuselages for the inevitable wires, hoses, and
fluid lines. At least in the inaccessible portions of the aft fuselage.
That way, when it's time to change or upgrade, you simply use a string
or one of the old wires to tow the new line through the corridor.

Thanks, and best regards to all

Do you mean conduit? Or is that aviatiou double speak to confuse us
mere mortals? ;>)

Yeah, I mean what you'd call conduit. But I didn't use that specific
word, since whenever I hear it I think of grotty, heavy, steel or PVC
tubing used for household wiring. And nobody wants that stuff in their
sailplane. Even Class 200 thinwall irrigation PVC is heavier than you
really need.

What I have in mind is more in the manner of a one-ply fiberglass
hat-section that gets bonded to the inner surface of the aft fuselage
before bonding the right and left shells together.

And besides, the term "Jeffries Tube" has been co-opted by Star Trek as
a way to turn ensigns into plot complications... :)

Thanks, and best regards to all

Do you mean 200 PSI? I think there is thinner, 160 PSI. There is also
aluminum tubing.
