Loctite advice Stuart Triple

[DEREK SPEDDING 1Participant @derekspedding1]

I am getting around to the Stuart Triple crankshaft  build.   After a years diliberation I have decided to go for the built up version.    I intend to use loctite and taper pins but am bewilderd by the choice of various types of Loctite.  Can anyone steer me in the right direction as to which to use.

I use 648 but 638 would also do.

638 is the classic choice for permanent bonds. 603 and 648 are slightly weaker but should still be good choices. I believe 638 and 648 have better temperature resistance than 603.

Don’t the manufacturers publish data-sheets helping users to decide the appropriate grade?

[Charles LamontParticipant @charleslamont71117]

Yes. Have you tried making a decision based on reading them? It is not that easy.
