I'm building up quite a few pics of things being stripped by electrolysis or cleaned after it or after painting but not sure if there's any point posting it all however.....
I said, a few posts back, that I had to deal with the (10mm head) ARB-clamp bolts. The subframe will only fit in my water-tank with the ARB off and having de-rusted all the other bits (just about) I'm keen to get the subframe in but the bolts weren't wanting to shift despite liberal use of penetrant (ATF) on them so I thought I'd try dipping the end of the assy in to get rid on the rust on the threads in the box-section. It's amazing how soft the process makes it.
I'd already got past the stage of a 10mm single-hex fitting the bolt and then a 9mm was rounding it so I was down to *mm or various small AF/Whitworth things I had lying around but nothing was shifting it so I started cutting the flange off (where possible) with the Dremel things.
I was just about to give up at midnight - having had a long day at work then dragging myself down to the barn about 9pm (to get tools for next day's work) - when It finally shifted with a 12-point 5/16AF socket on it. I'd burst a good 8mm one and things were getting desperate so it was a huge relief. As soon as it moved it came out easily so I'm pretty sure it wasn't the threads holding it back but the flange.
Got the other side in the tank now and will deal with that tomorrow. That head hasn't been touched yet so plan is to leave it well alone until as much flange as possible is removed than a 9mm hammered on should do it.
10mm becoming 8mm + part of flange cut off
hurrah. 1 ARB-clamp off without ruing thread in box-section
electrolysis really softens rust quickly
parts dried and brushed-off after electrolysis
subframe will fit in tank once ARB is off it
