Apologies if these are already in these 18 pages:
1" section of MTB innertube as lower headset gasket (fork removal required, suitable for 1" or 1 1/8" lowers),
Electrical tape as rim strip for lower pressure tires,
One half of a fork, clamped in vice as single sided truing stand (add your own feeler and reverse wheel to check dish),
More to come as I remember them.
