The SS rod is the spindle of a pedal on what Hobie calls a "Mirage

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?
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.
