Locktite

[michaelrbauer]

When assembling a crossbow should I use loctite blue or purple?

I like Blue. Holds well and releases easily when needed.

Blue 242, let set up over night minimum.

I use green (post assembly) on all the limb fasteners. For the most part, that is the only place I put loctite. Most people do not put enough beef into fasteners which is why you hear they come loose with or without loctite. If you put enough torque into a steel fastener that goes into aluminum, the metal under the fastener head will gall and lock the fastener in.
That been said, use any medium loctite anywhere on your bow. Use as little as you think you can get away with. For example, a whole drop of loctite in scope mount screws is too much.

Hi Michael, and welcome. I've seen the colors of loktite vary so make sure you get the medium or low strength. I use the blue medium strength loktite.

Boo nailed it, lot of folks use too much, and that just makes it much longer to set up. I put the drop on a piece of cardboard, or something, and touch the bolt to it, if you feel it is too much, dab it with a paper towel.
Less is more sometimes!

Just remember that there is a big difference between dried Loctite and cured loctite, I always let it sit over night. As already stated very little is needed, just a tiny drop on the tip is all it takes, no need to apply it the whole length of the threads, by applying it on the tip, when you screw it in it will get evenly spread over all the threads. You also want to make sure the bolts/screws are free of any grease or oil before applying the Loctite.

Does anyone know the proper torque specs for any of the fasteners?
Manufacturing requires certain specs, so should reassembly. Knowing these numbers would help. While working with race and street engines, we use inch and ft # wrenches for every fastener.
