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. Andrew (* 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. |
