A list I have cobbled together and found - some of the potion recipes don't seem to be working and I still can't repair.
Armor:
improving leather armor by combining it with a mobile kitchen (and mail armor by combining it with an anvil). When you do it, the stats improve. Do it a few more times and the stats improve again. You can keep repeating this process and eventually it stops improving.
Cloth armor + leather scraps = leather armor (random)
Leather armor + metal scraps = metal armor (random)
Leather armor + scale scraps = scale armor (random)
Cooking pot + hammer = Battered cooking pot (can only be worn on head)
Needle and thread + 2xCloth scraps = Cloth armor
Pumpkin + knife = Pumpkin helmet
Log + knife = Wooden stake
Leather scraps + anvil = Cloth armor
Metal scraps + anvil = Metal armor
Leather Armor + Mobile kitchen = crushing resistance +5% (first time) slashing resistance +5% (second time) (Could be random)
Scale Armor + Anvil = crushing resistance and slashing resistance +5% (2-3 times to apply both)
Mail Armor + Anvil = crushing resistance, slashing resistance and piercing resistance +5% (4-5 times to apply all)

Ore of any kind + furnace = metal bar of any kind
Jar + Beehive = Jar with honey

knife + wood branch = arrow shaft
Sinew + Sinew = bow string
Bow string + branch = bow
