So does it work. In short no :bang:
Firstly, to remove the tank I had to raise the vertical slide further than the screw that moves it.Lowering it back I ended up with a burr on the phosphor bronze nut. Had to remove the nut with the slide precariously balanced on cribbing timber, mill off the burr and re-install in - all a bit of a drag but then it was mechanically back together.
So does it work. In short (Still) no :bang:
All the servos work but we have no spark. I'd had enough by then so clean up and have supper and a couple of cans of 'Old Speckled Hen'
A bit of prodding this morning and I find that one contactor was a bit sticky, clean it up, re-wire a few bits I wasn't happy with and off she goes :ddb: :ddb: :ddb:
Lets do a quick and dirty test. Stubby bit of copper tube as an electrode with a block of EN8 steel as the victim

So what was the result. Well in about two minutes we've sunk the copper in 70 thousandths of an inch. So we're back in business and maybe now I can make that 5/8 UNC x 2" grub screw with a hex recess that I needed for my Edwards folder re-build.
Lets hope these bellows last longer than the previous ones as it was an unpleasant messy and dirty job.

(* later correction - it's a 5/8 BSF x 2" grub screw)

Hi there, Andrew,
It's good to read your post - that's a result! :clap: :clap: :clap:
I remember that the green soup was part of the problem but I've forgotten how you needed to resolve that part.

Hi Andrew
It really is amazing what that Old Spreckled Hen can do for you. Just shows job fixed.
Cheers David
