LiOnHeart threads...

[bwaites]

I just took my LiOnHeart completely apart for the first time and noticed that the body threads have a very rough feel to them in comparison to my VIP, which is like butter smooth.

I'm wondering if I need to do something with them. There is no apparent debris anywhere. Cleaning them with a microfiber cloth really had minimal effect.

Anyone else run into this.

This is one of the CPF SE's #13.

Try blowing them out with compressed air, someone reported that this completely fixed his problem.

Compressed air worked for me. Also, be careful when blowing the head threads to not blow debris into the reflector/lens area through the board holes. I used about 3-4 lbs of pressure, no more.

Tried it, no help!

It goes together fine, just seems strange because I can't really see, or feel to my naked hand, anything abnormal.

The tinniest lil dab of Nygel lube on the threads did the job for me. Smooth as silk now.

Nygel lube?

I am not sure on this but I think the positioning of the O-ring in the head might cause a slightly different feel than some other lights. Since there is only metal-metal contact while screwing the pack in until it is all the way attached?

I used a nylon brush and some fresh lubricant to solve the problem on mine. The metal filings aren't always visible and need to be agressively removed with the brush holding the head lense up to allow them to fall out. Remove o-ring first and wipe off. I did a lot of research on lubrication on CPF threads, from discussions about expensive Shurefire grease to automotive electric lube, and ended up using a 'dry' molybdenum disulfide multipurpose lubricant i.e. any high quality lubricant which is not expressly for PREVENTING electrcal conduction. Graphite, silicone based lubricants will work.

How about the O-rings? I've heard Nye lubricants recommended, but which is best for O-rings among the many Nye lubricants? Or other lubricants?

For o-rings, use either a pure silicone grease (sometimes called dielectric) or get some teflon lube at Radio Shack.

Nyogel 759G is for the threads, not o-rings. It's what Surefire uses. I just ordered some from SurefireParts. Great guy to buy from. Thanks to whoever recommended him.
