1) Locktite 290

We use about 20 different Loctite products in our aerospace assemblies. Callout for Loctite 242 seems more widely used in critical components.

So much to learn from OST builds.


I bow down to you sir m(_ _)m

NEVER bow to another.... you'll miss the performance

seriously... I've failed at SOOO many things in my life it isn't funny.. I eventually found something I'm good at... it only took 35 years for me to find it ... but thank you for the sentiment

I use the 290 for one reason... it is wicking.... (it seeps into the threads and then sets up) The 242, and other thread lockers don't have this capability. Why is wicking important to me... simple really... it allows for fine adjustment in the jackscrews, and once set, I don't have to remove them to apply thread locker...


Now as to how critical it is... it isn't that critical... for once the manifold is bolted tightly(14ft/#s) to the head the jack screws could (theoretically) come out and fall away, the manifold isn't going to move once tightened.




Now as to magic... watch these machining marks disappear.....


going....








gone!

More to come....
