    When it was first released the name on the can was "Triflon". My best guess is whomever owns "Teflon" bitched, or someone else pointed out that there was no Teflon in it and the name changed rapidly.

    My wife insisted that I get a sleep study done (in 2010) because my gasping for air was waking her up at night. I didn't know I was doing it. Evidently there was some snoring too. I always felt more...

    I already have a couple and passed another one up this weekend for $100 because it had a 1/2" shank. Maybe I need to reconsider since the prices appear to be going up.

    I used to keep one on my flash drive but these days it's just a google search away. When looking for online copies be sure to ad "PDF" to the search. The 718 and 618 use the same small parts.

    Not interested in selling at this time. I don't know how common they are and just wanted the photos to be available on the site. I only found a couple of pics on the internet and little information.

    Schaublin hand oiler

    I bought this Schaublin oiler at an antique mall this afternoon. I'd never seen one before so I thought I'd share pics. I don't know how common these are, seems like I'm always reading threads where...

    Yeah, you can't go by dirt in these things. They are filthy on a good day. I made another video from testing different locking piece angles for shooting suppressed. I used a high speed camera to...

    I reload all the fired brass from my fluted chambers. Before I quit counting some of it had been reloaded 12 times, probably more now. The cases look like crap because of the lines and I only shoot...
