Hey Grizz, It's mucho frio en la casa! LOL It's been raining here in SoCal for over a week and isn't supposed to let up until monday or something. My backyard is flooded. I can't get the tools out of my truck because if I step outside a terrencial down pour happens. LOL. Don't worry, there is a taunu (spelling?) on my truck. I have to go to get material tomorrow, and that will suck. I also need to do some spraying because I have an install to do on sunday, and the product isn't ready. I don't want to spray in my garage, but I guess I have to.
Anyhow, your prize is wrapped, just sitting here waiting for a mail trip. I'm not sure when that will happen, but I promise it will be soon.
I added BLO.
Everyone can feel free to add abbreviations to this forum, but lets keep it woodworking related.

Learned one years ago from a friend that worked at Los Alamos. When the ordered sand they listed how much as a Butt-Load. A Butt-Load is an actual measure equalling two Hogshead.
Actually "about six seams", which amounts to roughly 450 gallons. Never explained why they did that.

Test will be next Friday, it is not open computer you must memorize all the terms and be able to list them as kolwdwrkr has printed them. You do not want to know what happens if you fail…. (laughing)

kolwdwrkr Thanks for the list printed it and will have it around, somewhere and probably will not be able to find it when I need it. (laughing)
