Thread: Plastic Gears For Skull

Tweet

It's been awhile since I've posted anything, anyway!
I have this animated skeleton from sams club, brother got it for me for christmas pretty darned cheap.

I let someone here at the zoo borrow it a few years and now it's my turn to use it. Turned him on, his jaw, neck and arm are all not moving.... yippee...
I can live with the broken neck, I can fix the broken arm, but it's the jaw moving I need.... I took his head apart, opened the gear box and alas, the one plastic gear that helps move his jaw, it's teeth are stripped.
Where the heck am I going to find the same gear!? I looked through all of mine and none want to match. Anyone have any ideas? I'd really like to get him working again. Thanks!!

Maybe try one of the store below. Or go to a hobby shop, buy a chunk of plastic (usually in the railroad section/or model section) and try to fashion your own replacement? Sucks when people don't take care of stuff you lend them...gotta love the "I don't know what happened, it was working the last time I used it."

I was able to fix a Tigger halloween contraption by getting some small nylon gears from Gismo. The key is correctly measuring the gear. Best to use calipers. Likely metric. Also watch for if the shaft is knurled. That means the gear must press fit. With nylon gears press fitting is tricky. You need the hole just small enough to fit tight when pushed onto the shaft. To large and it will slip. Too small and when you force the gear on the shaft you will crack the gear.

You might try servocity.com like spinman said you need to know the dimensions

Best of luck

You could always make your own. I bought a sample some of this cause it looks interesting and I was curious how well it works. I haven't received it yet but you never know. You might be able to build a better gear.
