Overview
Clockworks are useful for a few different things in OSRS including creating bird houses and making a penguin suit for the Cold War quest. The method featured below is the only way Ironmen can acquire them.
How to Make a Clockwork
If you don’t already have a POH (Player Owned House), you’ll first need to get one. You can visit any estate agent and purchase a POH for 1000gp or complete the miniquest Daddy’s Home to get one for free. The easiest estate agents to access are in Varrock or Falador.

Step 1.
Once you have a POH, bring a hammer and saw, 10k GP (if you don’t have a Workshop), 4 oak planks, 1 molten glass, and 1 steel bar per clockwork mechanism you want, and enter your POH in build mode. Choose any room hotspot and build a Workshop.

Step 2.
After the Workshop is built, go over to the Clockmaking space to build and then choose Crafting Table 1


Step 3.
Next right click to upgrade the Crafting Table 1 to a Crafting Table 2.


Step 5.
Finally, you can left click on the Crafting Table 2 and craft a clockwork mechanism. Each one costs 1 steel bar. If you are making birdhouses, remember that you will get a clockwork back each time you dismantle a birdhouse. So you only need 4 in total to do birdhouse runs forever!

That’s it! Clockworks are simple to make once you’ve built the setup. If you’re an Ironman, this unlocks birdhouse runs — one of the best passive training methods in the game.
