Clean your vintage IBM M2 clicky keyboard!

Step 6: Gimme props!

So now the previously gunky tray piece and all the keys are like new, and you're ready to reassemble. As you can see in the picture, the reinserted springs hang out like sailors still on leave, so you need to prop up the keyboard to give them some slack, just like you would with real sailors. I just happened to have a few L-shaped pieces of cut tile sitting around; you can use books or legos or whatever, but if the keyboard falls off and the springs are pushed out, it's square one! Be forewarned.
