How to remove the pinion gear from vintage brass gears for your steampunk project.

In this video I show you how to remove the pinion gear from vintage brass gears. This method is very easy and safe (use your safe glasses). It allows you to remove the unwanted parts without damaging the brass portion of the gear. It will allow you to keep more usable steampunk supplies. The tools needed As shown in the video you’ll need the following tools. A small hammer (preferably with a smooth striking face) A nail set or punches. It’s nice to have a set of punches that vary in size. A set of deep sockets or some old tubular hardware. A solid work bench. The pinion removal method The secret to removing the pinion gears is to fully support the brass portion of the gear. I typically use a socket or tube that has a large enough hole to receive the pinion gear but small enough to support the brass as close to the pinion as possible. Typically there is only one direction that the pinion gear can be driven out. You can determine the direction by closely inspecting the assembly. The larger part of the pinion should be driven away from the brass portion of the gear. Some gears have a kind of a grommet that is left behind after the pinion gears is removed. This grommet can be removed if you prefer it to be. These grommets have a small diameter on one side that is pushed through the gear. The other side is larger acts as a stop. The smaller side is typically enlarged with a peening method. This secures the grommet tightly in the gears. As with the pinion gear you need to

  1. You’re welcome! Glad I helped.

  2. Thank you…OMGosh…i really appreciate this video…I have quite a few of this gears that i tot were useless. but being a pack rat I stored all my clock gears…finally I can see them come to life…;)

  3. That’s great! I like the site too. I just started a blog on this topic also, the address is in the description of the video. Thanks.

  4. I WILL! I am a member of an online art community. Loving Mixed Media, run by Gary Reef. There are many people there who would be interested in this.

  5. You’re welcome! Thanks for watching, please share my videos with anyone that may benefit from them.

  6. Thank you, thank you, thank you!! I’m so glad I didn’t throw my gears out. I really did think I’d never get the pinion out!

  7. You can get about 10 gears out of an average sized clock movement.

  8. How many clock movements did you take apart to get that amount of gears?

  9. I’m glad I could help!

  10. oh thank you, I pulled and I slammed and angrily moaned and cursed in despair like a fool. great! :D

  11. Typically the pinion can be driven out in only one direction. If you’ve determined that you’re driving it in the correct direction and the hammer is not working you may need a press. If you have access to a drill press you can chuck the appropriate sized punch into it and use it (drill press not running) as a press. This will give you much more even and accurate pressure. I hope this helps.

  12. I have several pinons that are not coming out with a hammer, can someone give me advice?

  13. Although I have repaired a few clocks, I would say that I’m not an expert horologist. My videos are more for salvaging part for art projects. There are some very good videos on this subject on You Tube if you look around. Thanks for the interest though.

  14. well done. I just bought an old Sessions mantle clock with the westminster chime. The shaft that runs the hands is loose or worn to the point where the hour hand is rubbing on the clock face at the bottom half . Could you address that issue on your videos?

  15. Thanks for the feedback! I thought it was a little lengthy, I’ll keep it in mind when I make the next one.

  16. Thanks for this : ) It coulda been a lot shorter but still, appreciate you sharing your experience.

  17. Thanks!

  18. Dig it. Very informative!
