.... Or so was that lot described in the Rock Island military auction
where they sold off contents of one of their buildings that they want
to remodel.

I bid on it for no good reason other than liking the Thern 1/2 HP winch.

It turned out to be bigger than I expected.

But what it turns out to be is an aluminum degasser. Which can be
described as a big pole with base to bolt to floor (about 8-10 ft), a
arm, and a motor to drive a special shaft through which argon is piped
into molten aluminum. The point of a degasser is to remove hydrogen
that is dissolved in molten aluminum. Aluminum is so prone ot
oxidation that it dissociates water molecules, turning into aluminum
oxide.

2Al + 3H20 = Al2O3 + 6H

The hydrogen gas remains dissolved in aluminum until it cools down and
begins to solidify. and then forms bubbles, which ruins the
casting. Here comes "degassing", which releases hydrogen by stirring
molten aluminum and adding inert gas through the degasser and its shaft.

I can post pictures if anyone is interested.

That is one hell of an inaccurate description. Did it have a blower or
something on it which might reasonably have looked like a grinder? Glad
you were only wanting the winch. I'd certainly be interested to see some
pictures.

Here are some pictures. I made them while unloading. They are not too
good and I can take some more if you want. I wish I could take one
looking at it form the side so that you can see the swing arm with the
belt drive from the DC motor near the pole. It does not look like a
grinder.

You've got some really annoying flash-based ads on your site now, Iggy.
Damn things blinking so fast all I can do is close the page.

Hmm ... with flash and javascript enabled, I just see ads for a
CNC router. But I normally browse with both turned off.

Get opera as a browser, and you can turn both off by default,
and then in the site preferences (right mouse click brings up a menu
which includes that) on each site you can turn on javascript, "plugins"
(which include flash), or both. And with javascript, you can control
what things it is allowed to do and what not.

I never even knew that the had the ads until I went in with the
two turned on, because I normally browse without them except for sites
where I *really* need them to do something which *I* want to do. Lots
of sites which won't work without flash and javascript -- I just decide
that I don't need to visit them. :-)

Enjoy,
DoN.

I use firefox and adblock, and never see any ads. I highly recommend
these two free products.

Interesting piece of kit. Nice winch for sure. Where is the lance which
goes down into the molten aluminium, or was that not included?

I have a interesting project for this winter. I'll post some pictures at
r.c.m for people to see, but it will probably have to wait a few weeks.
I've gone back to using a film camera for most things as I got annoyed
with digital cameras breaking, losing my pictures and their batteries
going flat.

Best wishes,

Chris

I would say, buy a better digital camera.

A better digital camera will mean that those things don't happen so
soon, but they'll still happen in a relevant period of time. You'd be
lucky if a good digital camera lasted you more than 5 years. But pick
the right film camera and it'll last you a lifetime.

It's a personal thing. I like the idea that I've got a camera that I can
always get fixed. Also, I find that because film isn't free, the quality
of the pictures I get is actually better.

Best wishes,

Chris
