A couple of old clamps

[pritch]

I've had these forever. My dad gave them to me 30 years ago. They still work perfect, and I use them all the time.



Anyway, I have built an electrolysis rust removal tank and I wanted to test it out on something so I chose one of these for a test run:





I'm pretty happy with how it came out. After about 4 hours in the tank, I just ran it under the hose tap and lightly hit it with a wire brush then rubbed some Gibbs Brand oil on it.

Here's a link to how I made the tank:

Nice clamps and it seems to work great too.

Looks like that worked out great. Got the rust out of every nook and cranny too.

Nice rugged clamp, I like it :)

Datamp needs a picture of an actual one ....

How would that work-I mean, should I just send them a picture?

Couple tricks.
1 Scrub the Gibbs off with a Brillo pad and get copper wire to each piece of the clamp to the - side of the power. 
2 Stick it back in the tank and cook the rest off.
Lower the current as you get more off, and you'll minimize the black crap.
3 When you pull the clamp from the tank scrub it with Dawn dishwashing soap & Skotchbrite to remove the scum & black crap.
If the black crap hardens you need to media blast it off.

At that point you can either oil it or blacken it.

Thanks, Aunt Phil.

I am still experimenting with getting this right.

 Great clamps!! They have a deeper reach that any other bar clamps I have seen.
They would be just right for working thick stock, as in 3-4" thick or so.  All other only cramp the outside edges. 

Oh, if electrolysis leaves tough back stuff on your tools? A quick did in any kind of acid dissolves it instantly. But then you have to scrub with baking soda to kill the acid.

In the case of cast iron like these clamp heads, once you get them dry rub down with a coat of boiled linseed oil.
  Use your fingers so you don't have soaked rags of it laying around, and merely wipe the little excess at the end.
Cast iron and linseed go together like ham n eggs!
  Overnight the iron will become pitch black and shining, and its a pretty sturdy finish too.

I don't want to discourage your experimentation, after all I watched some of Buzzard Breath's Great Attempts to improve and refine the process for over 20 years.  It's good to watch a process unfold, and truth to tell I ain't sure if the successes or failures are more fun to watch. 

It took him 8 years to perfect tank filtration to the point of running a crystal clear tank 24/7.  Some damn funny piles of scrap went to the recyclers from those failed attempts.  The success on filtration came, and we got to hear 3 weeks of cussing his own stupidity for not remembering something he had known all along.  I was glad to be on an out of town job when I heard the story, nobody saw me laughing.

Nice clamps I have a couple of a more modern type that I use all the time.

I see snow on the ground there, you know the last time it snowed here, ice age perhaps.

And they'll still be usable in 2110 maybe 2210 with a little care.  That is if mankind is still here on the planet.
