Excellent progress so far Andrew. Feels good seeing something being properly restored from an internal disaster.
awemawson:
Thanks Steve.
Until the bits arrive there will be little more progress but this afternoon I've re-glued the corner of the Control Panel that was broken (not me gov!) and started sorting the corrosion on the card cage.
The rusty retainer with a sheared bolt in it I was able to remove by drilling out four pop rivets - then it could be grit blasted, the sheared screw drilled out and the hole re-tapped, and then the lot got a light coat of zinc spray before being re-rivetted. Note how I insert ALL the rivets before setting any to ensure that the location stays OK
The card guide bar, which is alloy, is more of a problem and I think I'll need to source a replacement. There are two sheared off screws in the square nuts that are supposed to slide in the extrusion - but they don't. The plastic of the guides themselves is very brittle and two have broken retainer pegs, and the bar itself is badly corroded.
Do any on you recognise the rack system to help sourcing a bit of extrusion and some guides - there is a logo in the molding of the guides, I recognize it but cannot recall who's it is - can YOU help ??
awemawson:
DOH - it's Siemens :lol: :lol: :lol:

On reflection, although I'd prefer to replace the extrusion, as a fall back , and if I can bully the current captive nuts out and down the extrusion, all I need do having cleaned it up, is make a length of tapped flat bar to slide in. 7.5 mm x 3 mm tapped every 20 mm nine times. There are two unused card slots, so I can steal their guides to replace the ones with broken retainers.
. . . now where is my 7.5 mm x 3 mm flat bar stored :scratch:
