Canon flash attach knob too tight
Jun 21, 2015 21:19:43 #
My Canon loaned to my daughter with 580 EX flash attached. When returned I could not remove the flash. The adjustment knob will not turn either way so I cannot loosen for removal of the flash. Much "finger" pressure applied but will not budge. Suggestions please.

Typical with plastic threads. Wrap a rubber jar opener disc or cloth around it and CAREFULLY loosen it with a pair of pliers.
Edit: I use a lubricant on the plastic zippers on my Jeep's soft top, and believe it would also help keep the flash's knob from sticking.

Yea, was wondering about that. Sometimes I start in the wrong direction. (Details...)

When you are looking at the rear of the flash the lock wheel turns to the right to loosen. I just tried mine.

Yeah, that can be confusing. Years ago, Chrysler used reversed threads on the lugnuts on the right side of their cars. That resulted in a lot of broken studs.

it depends on the orientation.
consider a bolt with a nut if the bolt head is at the top then turning the bolt anti clockwise will loosen the nut but if you hold the bolt and turn the nut clockwise then that will loosen also.
Bolt at the bottom and nut at the top it works the opposite way.
the nut on the flash is compressing the hot shoe so with the camera below the flash the nut must be moved from left to right / insert spanner to the left of you and draw it across in front of you to the right.
that is camera spanner you, if its spanner camera you then you would be going right to left.
Does that help or is it more confusing?

Yes Blackest, I understand. For the OP it is easy to turn the wrong way. I usualy leave mine loose enough that I don't have a problem. It needs a arrow.

Thankfully lefthand threads tend to be fairly rare. bicycle pedals can be an exception, with the idea that if the pedal moves within the crank it should try to tighten rather than loosen.

luckily most taps and faucets use a regular right hand thread and we learn as kids which way shuts the water off and which way lets more water through i think most of us did it the wrong way a few times as kids.

I have a similar problem with a third-party off-camera coil cord. I did lubricate it (which helped) and I took a silver Sharpie and marked the direction to unscrew the connection so I'd never turn it the wrong way.

Sorry but it was right hand on the right and left hand thread on the left

Yup. If you looked at the end of the studs they had a big L.
