Master Space Bar Lugs

Post by BeebMaster »

Finally got round to asking...my thumb is now nearly destroyed from trying to make the space bar register without the two little lugs either side holding it up. Anybody got a couple of these for a Master 128?

I've got broken Masters, but not broken keyboards, so I didn't want to cannibalise anything or swap the whole keyboard just for want of the lugs.

These are the sort of things it would be handy to get dimensions of, obviously for yourself, but also for any forum members in the future who might need them. I could easily rattle a design up and 3D print them - at no cost of course, ridiculously small amount of material to make, whether that’s FDM, or SLA.

Though I don’t doubt there’s going to be many a knackered keyboard knocking around someone will be able to help you with.
I'll be highly medicated and my humour can be twisted, so when I offend you, its not intentional, honest :lol:

Getting replacements 3D printed would be a good idea. I just decided to have a fiddle, and in fact the right-hand lug is still on the space bar, it just wasn't connected to the wire rod. I tried to make a replacement for the left-hand one with a bit of cardboard, but it ended up going inside the keyboard so I've lost it now. Possibly the missing lug is in there somewhere as well, but it doesn't rattle like it might be. It's a lot better with just one lug connected properly. I think it would be just as easy to fit a keyswitch in place of the lugs, it doesn't need to be a working one, just something to hold up the space bar.

To be honest, I think that even if I had the original part, I wouldn't have the skill to fit both at the same time and then persuade each one onto the wire bar, and then lift the space bar over the keyswitch to fit onto it. I suspect that's probably why it's got one missing in the first place, probably lost or broke it after taking the space bar off to wash it and couldn't reassemble it.

It looks like it was intended to have 3 keyswitches, so I think I'll find an electrically dead but mechanically functional old switch and use that.

Ach, I bet you’re underestimating your ability. I’m sure with some patience, a bit of time and a bucketful of swearing, you’d get it no bother :lol:

Anybody got a spare lug they can send me please ? #-o

Whilst fixing a dud key I took the opportunity to remove all the keycaps and give the keyboard a good clean. Bad idea.
In doing this one of the space bar support lugs has pinged off somewhere. It may actually be trapped inside the keyboard cavity itself, with no way to recover it.
To be clear its one of these I'm after, ta,
