No school, which of course means some time to snuggle up with a good book. Finished another one this morning- excellent read, but it leaves me in a bit of a bind... Do I start another book or wait for my late Christmas present to show up and read it?! Guess I'll start another one, there's already too many on the pile!
The top shelf have been read in the last couple of months, the next two down are on the "to read" list. If only there was just this one bookshelf...
I also went in to play around in the shop for a bit this afternoon. Got my grades mostly done for parent teacher conferences coming up and mucked around with the TIG welder a bit more. Spent some time trying a few different things I've read about, and am starting to get a little success!
Some great resources for welding:

I could spend hours on that second one. Who'm I kidding, I could spend hours on both of them. Below are a few of today's tungsten's. A few people suggested I had my current set too low, so the one on the left was at about 150 amps, AC smooth, 1/16th tungsten and filler rod. Didn't last more than 5 seconds. The next was turned down to about 100, the next 80, and the last two are at 65. I switched to 1/8 rod on the last tungsten and managed to keep it going for a long time, although I probably *should* have changed it because it got contaminated...
The results. Might not look like much but it is getting better (I hope)! It can be tough welding over top of junky welds but they are starting to smooth out. Finally getting the dip/jump rhythm. The thicker rod makes it a lot easier to dip/jump for me.
I'm also starting to get the hang of telling when the base metal is too cold or hot to weld. To cold and the puddle just won't carry and the rod beads up on top. Too hot and it sinks in and looks "filmy" after it cools. Just right- you get a nice puddle that is easy to carry, the rod melts nicely, and the finished weld is nice and shiny with the "stacked dimes" appearance.
Three or 4 more years of practicing every day, I might just be able to weld aluminum. Then I can start trying the thin stuff.
