oxide cleanup

removed all the trims, borrowed a good friend’s pressure washer, down to the bare metal is as far as it goes.  can see clearly now how previous owner took off too much of the AlClad pure Al layer with something rotary (sander?).  bozo flat headed all the backed rivets and shook half of them loose too.


the steel lights did the worst damage to the aluminum.  only way to find out if it there is enough aluminum left underneath is to remove all the oxide layers.  i’m kinda fascinated how the Fe (iron) migrated onto the aluminum, the lights might have been plated (Cr) or dipped (Zn)….


above before and below after quick hit with medium wire brush wheel.



no, actually the worst damage was the tweakers.  my lock will be easier to open than that one was…..




three sheets

finally back to work on Two.  the wet winter and missing roof vent covers means the remaining floor is coming out fairly easily.  the original plywood is in amazing strong shape where the over cover chipboard didn’t rot it away.   since i’m not taking the shell all the way off, this is as far as i can do at once, three sheets of new plywood, then do the other half once the front shell is re-attached.  THIS is my summer art project !!!


frame is in good shape.  time spent now on the frame before laying the new ply will be time well invested. some cleaning, wire brushing, sulfuric acid, primer, seal coat, yeah.  whole lot of littles ahead !!!!


and then all again on the back half…

Vintage Brakes

so these are called Warner electric brakes, designed by the guy who designed magnetic speedometers standard in pre-computer automobiles.  clever design, but i think the standard modern setup is in the plans.

here’s the hub off, friction pads inside the hub, and magnetic coil is the ring around the spindle.


closer look at the hub pads,


i assume it works like: give coil juice, it gets torqued by pulling these pads to it and then the doughnut is forced to turn a little bit.  that turn then pushes on the pad ring to engage the hub.  heres a closeup of the tab that sticks out of the coil ring where it can push on the ring on either side (forward or backward same power).


so yeah, i’m back to the wordpress blog thing, which copies automatic to fbook.



santa screwed this year?

ya ever notice how an iced drink behaves on a hot day? the ice gets smaller sorta steady like,  then theres a pause, where the cubes are about 1/3 their starting size, and they don’t change size much for a bit.   then, suddenly they’re gone?  saw a version floating on the net without any attrib, so this version of the graph is direct from  NSIDC, the folks who actually count the icebergs.


and why ? well it seems the ocean warming has warmed right up to the doorstep of the icepack, and the “plugs” in the straights aren’t forming.  see the really dark red spots in the bering straight? and like all from Greenland to russia?


don’t worry, Santa has water pontoons on the sled.

too bad for the reindeer tho,




Perigee Moon Scores

SuperMoon.  harumph.  bullies shame the smart, and american schools teach to the lowest common denominator.  well, it ain’t common, it’s called “Perigee”, when the Moon is closest to Earth, as opposed to “Apogee” when it’s the furthest.  One of these days we’ll rid the earth of the last of the science shamers…

whatever, tide was SUPER LOW, and that is SCIENCE WIN!!!!




As Above…

traditional morse code goodbye is “73”.

that is –… …–  or dah-dah-di-di-dit di-di-dit-dah-dah.

say it fast.

nobody really knows the meaning, but the usage and rhythm i always think:

“As Above So Below”.

As Above,


So Below


dead dinosaur distributions

yes, i admit, this is how i “recycled” my engine oil for many many years, usually didn’t bother with the gravel however….


kinda makes ya wonder what’s the big deal about a pipeline?  i mean, whats just one more oil leaking greed vein?


more battery lies

ok, these are HP batteries.  one is as expected, full of cells.


but the other has these black cells, ive never seen black cells before?


oh wait, those are not cells, those are hollow plastic spacer tubes?


i guess even the big buys cut corners when they can?

would never tell from the outside that 1/3 of the cells are missing inside?
