I'm getting ready to do a boring job on the mill and I am trying to set up my boring head, Elliot 1/2 to 12" type, and the damn thing appears to be seized up. I've removed the large grub screw from the side that would appear to lock the slide and I've removed the large diameter 'plug' that threads into the slide to retain the boring bar but I can't see how to disassemble it further; it's been soaking in penetrating fluid for 2 days but it's still stuck; the adjuster turns about 0.008" on its scale but then it goes tight and the slide doesn't move. The design is similar to the Excel one that G&M have at the moment

it doesn't have dovetails but instead it has a cylinder that slides within the head. If anyone knows how do dismantle this or, better still, has a copy of the manual, I'd be most grateful. TIA, Martin.
