    TWIC and airline travel

    ORD was such a mess before Thanksgiving that they basically pushed everyone through security on Monday 12/1. No taking shoes off, no scanners. At MIA I got a TSA precheck. Will probably get global entry just to speed thing along. tb

    TWIC and airline travel

    DHS randomly issue to TSA precheck's on boarding passes as an incentive to get precheck and global entry. They are not selling as many as they thought they would, thus the precheck freebies. Since almost everyone here has jumped through the TWIC hoop, and supposedly it all the same government...

    Critique my homebrew PP blending whip

    I'm not a big fan of the QD's. I have male DIN's on both ends of my mix whip.....I use a hand tight 540 (O2) to female DIN, and a 580 (Helium, Argon, etc) to a Female DIN to feed the gas. The only thing I did not add was a one way valve. The QD's have a tendency to leak over time. Plus in a...

    Converting Bauer JR II Gas to electric

    Ok, just went to look at my Bauer Jr.....from the Norfolk facility.....It has a Lincoln Electric 3HP 3450RPM with a 56H frame. Model # SRD2S3T1B66TP1B. My guess is that Germany ships bare block/frames to the US for local configuration. Why ship motors (weight issue) across the pond. tb

    Have you been scammed at the dive shop on tank service work?

    Can't prove it...but in the Chicago area the hydro shops(fire extinguisher companies) are in cahoots with the LDS. Use to be $15-20 a hydro direct. Last time I went in it was $38-45 and that was shopping around. I'm sure the LDS squeezed the hydro facilities. I load up the truck and head...
