I don't see why that's a problem. The floor curves in the other direction, so, on average, it's flat.

Seems like it's been upgraded to twelve months of the year now, which is why I'm flying back home to California for awhile next week; with a tool list of course.
Maybe the curve explains why I seam to be going around in circles.
Made an interesting discovery. After polishing I was using Window cleaner to remove the residue from the cutting compound. Think the ammonia in the cleaner was oxidizing the aluminum. I repolished and washed it off with water.
Also straightened out the crane rail.
Yes, that's precisely true: ammonia does oxidize aluminum.
WD-40 works well to cut the greasiness of polishing compounds. I'm sure plain old kerosene or white gas would work as well, but I happen to have lots of WD-40 around the shop.
I tried kerosene, it worked great, but I probably should add a layer of wax to keep the shine and thought it might stop the wax from adhering. Too many interactions to consider.
Yeah, the WD-40 probably would keep the wax from adhering. Kerosene might not leave as much residue, but it is a petroleum product, so who knows.
Anyway, looks like you've got it under control. Looks nice. Now go slap it in the water and make your arms sore!
I've been pretty fascinated with the advancements in flashlights lately, and bought myself a little something for Christmas. The
Astrolux S41 uses four Nichia 219B LED's and puts out around 1600 lumens. And since those LED's have a high CRI index (closer in color to sunlight), it seems even brighter. I opted for a larger 3400 mAh battery which required an extension tube to extend the use and make the body actually large enough to hold. Unfortunately everything showed up except the tube, which is pretty much useless, so I ventured into the shop and made a temporary one until the slow boat from China arrives. It's been a while since I've generated any chips just for fun and it felt pretty good. :)
