Universal Joint Failure on my Drums
My double kick pedal has suffered a failure in the joint that drives the left pedal. Here's a picture of the joint with the rubber boot removed.
 What happens is that it's fluid on one axis but the second axis is really really tight, and doesn't move unless under extreme force. A rubber mallet will cause it to rotate, for instance but a foot, and a hand, will definitely not budge it. What causes a joint like this to fail and is there any hope for repair on a joint this small? They don't make the part anymore and new pedals are multi-hundreds of dollars. |

Maybe submerge it in some penetrating oil overnight and see if you can work it loose, then find the root cause of the problem

It's all one piece, from the bar to the joint. I'd have to weld it in place if I got just a new joint. I don't have welding equipment or the talent to do that
 The joint itself is about 1" - 1.5" in length. It doesn't feel seized as much as it does broken, as if the clearances are no longer there. |

What brand is it? You may be able to score a replacement rod from your local drum shop.
My Luwig double kick is packed away in my cases or I would look at that for you. I would try soaking it in oil overnight. These are the same design as the 911 steering shaft joints and that sometimes loosens them. Any pics of your kit?

Yep, soak it in pb blaster.....then work it work it work it.....
if it frees up keep spraying the heck out of it with pb until all the rust is gone..... Clean it up with some brake cleaner, then oil it up......

The first thing I'd suspect is bad grease.
Every_single_thing produced these days seem to be made with bad grease. The second thing I'd suspect is bad bearing clearances and/or procedures during a rebuild. That thing looks brand spanking new all around. There's no reason for premature failure. |

What causes the failure is the lack of lube and the shock hitting the joint every time you bang the pedal. It seems almost like the pivot pins and other parts will do a "weld" once the lube gets squeezed out from the moving parts. I'd suggest getting an aircraft type of universal joint since the one pictured is probably the cheapest design the maker could come up with. Appears there is no way to lube it and if the angle between the two ends gets very large and any twisting occurs then it will surely seize. If you stay with this one, I'd suggest putting a hole in the rubber boot and every time you play, squirt a bunch of gun lube such as used on those dreaded assault rifles (CLP, Frog Lube, etc) in there to keep things wet and loose.

steering ujoint used on cars. you can even get them with needle bearings. bolt on and weld on. depending on brand can be expensive but should be able to find something at a junk yard that would work. around here you can buy any size ujoint used in the oilfield on reachrods.

 i'll give the joint a soak and see what happens. The seizing started during verse 1 of "All Nightmare Long" by Metallica, and by the chorus it had stopped moving. It was like thirty seconds of playing between working properly and stuck, not a long term slowing down. That's why I'm confused. Quote:

Most of what I play uses both pedals. Without the left foot on bass, I'm left to about 15% of my music library. I don't mind playing the Misfits, The Sword, The Riverdales or even Weird Al, but my primary love is heavy metal. It's a huge stress relief to get behind the kit. I feel incomplete without the left foot on bass though Here's some more stuff I enjoy playing if you're curious. |

Lyrics are awesome, too. For example Then: Crazy, I'm crazy for feeling so lonely I'm crazy, crazy for feeling so blue Now (well, just a few years back): I push my fingers into my eyes. Slipknot - Duality - YouTube (I'm 56 - this peppy little tune rocks) |
