I miss when rust removers and paint strippers worked.

That's what I do. I put an old battery on the charger, and then run jumper cables to the work and sacrificial pieces. The problem is it usually ruins the battery after a few weeks of use, and so it still poses a problem. I don't have that many spare batteries laying around.

The jungle site has DC power supplies in the $40-50 range.  Lots of folks on the E-tank group on FB use them.  Easier to dial in and won't wear out a charger or batteries.   I need to get one myself.

Do you have a specific model that they recommend?

Has anyone suggested trying a heat gun yet?  Or a torch, lol.

Makes it worse, the paint tends to burn on, the amount of heat needed to incenerate it would require some resources...

I just went through the group real quick to see what popped up. The latest one mentioned was "Galook" .  There are a bunch of them that look pretty much the same and have equally silly sounding names.  Looks like the prices have gone up recently though.

Thank you all for the great info. Gathering up stuff now for an e tank.

 

I used to be a fan of vinegar,  last batch I did had a cast iron engine and hydro pulleys. It, for lack of a better word "delaminated" them.

Is that right blaster? Come to think of it some leaked out of a Harley master cylinder and it took off  pain. Or was it dot 5 ? CRS but prolly got some of both in a open container that can't be used in brakes.

 

DOT3 is the paint remover.  DOT5 is silicone based and won't hurt paint.

 

BTW, is Naval Jelly still around?  I used to use that for a mild rust remover.

HCL for tough stuff.

Naval Jelly is still around, it can be hard on your base metal, its Phosphoric and Sulfuric Acids...works though

I'm partial to the E-tank method as well.  For my power supply, I grabbed an old Lenovo laptop power supply I had kicking around.  It was rated at 20V 10A.  I cut the DC plug off of it and spliced on a battery tender quick disconnect.  That gives me plenty of options for quickly connecting and disconnecting ring terminals or the small spring loaded battery clamps.  

I tend to pressure wash my parts first, then drop them in the tank.  It always takes off like a handful of alkaseltzer tablets.  I knew it would handle rust, but it surprises me how well it does with removing old paint as well.  It will typically lift the paint and eat all the rust in a matter of a day or 2.  Then I clean the parts and put them on a shelf with the intent to prime them.  I never get around to it in time and they all collect surface rust.  Then I repeat.

Would an old computer power supply work?  They are available, a dime a dozen.

I owned a computer business years ago.  I had a LOT of power supplies, but ended up pitching all of the old computer parts when I moved.  I do have old laptops and their power supplies, however. 

Now that my sandblaster is upgraded, I guess I can make an e-tank for good measure.  (I have an unused / undesignated plastic 55 gallon drum gathering dust.). I just need to find a spouse-approved outdoor location for it.  Hydrogen gas accumulating in the shop where I weld isn't a great idea.
