Red LocTite as Glue for SS Rod Into 6061?

[(PeteCresswell)]

The SS rod is the spindle of a pedal on what Hobie calls a "Mirage
Drive": http://tinyurl.com/y9a4xr3a

Basically a couple of pedal-driven flippers that propel a kayak.

I am fabricating new pedal cranks for mine after breaking two of
Hobie's.

The SS spindle is 15/32" and I would drill the same-sized hole in the
solid 6061.

I do not want to get involved with cutting threads in SS, so I am
thinking maybe just put the spindle in there with Red Loctite.

Doesn't seem like there is that much stress on it - and Hobie does
something similar where then do a force-fit of one end of the spindle
into the far end of their alu box stock.

Does anybody see any hope for this?

I'd see a lot more hope if you used a sleeve retaining type ... and
be aware those compounds require a couple of thou clearance between
parts . There's likely more torque being transmitted than you think ,
have you considered using a taper or roll pin ?

Greetings Pete,
The two metals you want to bond are not considered "active. This means
that some anerobic adhesives won't work well without a primer.
Furthermore, from your description I think you are asking if a thread
locker will do. A product that will work very well for your
application is Loctite 638. It has a shear strength of 4500 PSI. It
does not need any kind of activator and sets up in 4 minutes. Full
strength cure takes 24 hours though. Good stuff, and good for what you
want to do.
