Minimal blogging today

We have had about 25 days of rain but today was relatively clear so I spent it doing outdoor things (getting firewood in and looking for scrap iron along the railroad tracks for blacksmithing (got 40 pounds of good high-carbon steel bolts and spikes)) This evening, we went to a presentation on the Lone Jack Gold Mine which is about 20 miles from where we live. First staked in 1897, it is still in operation today. A fascinating bit of history! I am spending this evening dismantling a dead microwave oven to salvage the power transformer -- I am building a small spot welder for sheet metal and blacksmithing work and the cost of a power transformer with this sort of power would be several hundred dollars. This transformer is 120 in and has a rated capacity of 1,500 watts, more than enough. By taking off the old high-voltage secondary (about 2kV) and winding on a new low voltage/high current one, I will be able to build my own for a couple bucks worth of copper rod for the electrodes. I have most everything else...

Sheesh, I meant 5kW/12kW. Units. Both of those are 'max load' numbers - _not_ 'voltage out' numbers.

You know about Boeing Surplus I assume.

Winding transformers is a royal PITA.

I have an autotransformer that I think is rated 240V/20A in, 60V/80A out -> 5kV. I'd have to dig up the paperwork to be sure, but I'd be willing to let that one go.

I also have a 240V, 12kV isolation transformer that I've forgotten the ratio on. It's at least 4:1 also. This one I could loan - it did run $800. (And is 100lbs. And was shipped wrapped in BUBBLE WRAP and cardboard. The driver dumped it on my concrete porch as a pile of plastic, a near-invincible toroid, and 6 sheets of cardboard. Glad I didn't have _that_ sliding around in a truck.)
