Thread Question

[Illumination]

Did Peak use different thread cuts on different vintages of the Matterhorn?

I have a 3 led Matterhorn that I bought a while ago with a stainless lug body and a 10280 lug body.

Separately I bought a 1 led Matterhorn with a stainless pocket body and a second stainless lug body.

The 1 led head fits on all four bodies but the 3 led head only fits on the original two bodies.

Any idea what is going on?

If one or the other or both threads in the head or the body is off due to tooling wear that may be the reason. If you would like to send them back I have a very large hammer and will make them all fit.

i took your response as encouragement and used my own hammer...

by hook or by crook (actually a fair amount of force) I was able to open the obstructions in the threads

one of them is still a bit stiff...but getting smoother every day. gives me a reason to turn the light on and off!

next stop may be an eiger head for the collection...

Illum - You used a hammer to tap the head into the body? It didn't destroy anything? You may also want to use a little metal compound. Put some on the head's threads, take out the battery, and twist all the way down and up several times until it starts feeling looser. This should help clean up some of the deformed metal. After cleaning the compound off, you may want to use some polish, clean that off, and then use the lube of your choice and reinstall the battery. It should feel like new!

Best of luck,

Thanks. I didn't actually use a hammer. I was responding to Kurt's tongue-in-cheek response to my question.

I was frustrated with the thread and just tightened to open up the thread. It worked, but one of them is still a bit rough. I like your idea of using a metal compound to clean that up...are you referring to something like Flitz (which I understand is a polish with some abrasive to help clean) or something else.

Thanks for your suggestion. Very helpful.

flitz works. i used flitz on Ti lights to smoothen the threads..should work great for you.
then i clean em out with an old toothbrush

Illum - haha I read these too late at night! . As you mentioned and Clint agreed, Flitz works well, as does Simichrome, or on the less expensive side Blue Magic Liquid Metal Polish...I personally have Simichrome and Blue Magic on hand, but seem to use Simichrome more often. I think it's a little more abrasive and is more comparable to Flitz...Blue Magic can usually be found more quickly, especially at auto parts stores and probably Wal-Mart. I don't remember where I got it...it's been a long time.

Illum - you'll have to let us know your results.

Clint - As usual...thank you. :twothumbs
