IBM Model M keyboard repair tip

I think some of us like the INM type M keyboard... If you are brace enough to take the heatstaked 'sandwich' apart and replace the stkes with screws (I post the method for doign that some years back), it's easy for one or two of the 'flaps' to jump out of position when you're putting the bits together again. You then have a couple of keys that don't work and you have to take the whole thing apart again. What I do now is insert a flap then slightly stretch its spring and press it over the rear of the key plunger housing, forcing the rim of the housing between the coils of the spring. It'll stay like that, and the flap will be held in place. Fit all of them, put the rubber sheet, the membrane sheets and the base plate on, and screw it all together. Then unhook the springs by running a screwdriver along, and fit the keycaps. The plastic keyframe can be cafully cut between rows of keys (it sometimes breaks along these lines anyway). You can then use parts of 2 damaged keyframes to make one good keyboard. I am not sure what the offical sixe of head for the casing screws is. It's often quoted as 7/32", which turns out to be a smidgen more than 5.5mm. I've found both my 7/32" and 5.5mm nutdriver fit fine. Somebody was looking for some tpye M casing screws. Did you find them? I spent the afternoon making a good tpye M from bits of 2 broken ones, and thus I have soem bits over :-). I never thown anything away so I've got a box of flaps, screws, etc. I could probably be persuaded to part wit hthe casing screws... -tony
