Title: Best way to remove collet knob caps?
Post by: Greg Norman on May 21, 2008, 02:13:14 PM
I was wondering if there was a great way to do this without marring the finish of what are sometimes old, fragile caps.  I have been using thin blade screwdrivers, and razors to pry them off, but there must be a better tool right?
I am talking about these (blue cap)-

I tried to search for a thread that discussed this but came up short.  
Thanks.

Such things to tear eyebrows from a beauty shop may help, just bend ends 90 degrees:

I saw some. But sometimes they are too short to bend.

I've used needle nose pliers. Carefully.

I've always used my finger nails. But if it's been a difficult week, then I use a razor blade....

I've used single side razor blade.  Or utility knife blade.

worked pretty good for me.

Greg,

There is a correct tool.
RS Components used to sell two different sizes, I purchased mine years ago.
They still should be available.

I use a scalpel.  

This is useful because I am able to do vasectomy's for a sideline !!

Greg,

-Ever noticed how some colours are more prone to breaking than others?

-On Neve consoles it's always the light blue coloured caps which crack/snap.

Here's my best tip:

Get a plastic knife -like those handed out free at the delicatessen- and file down a thin -but not too sharp- edge on it. Take the sharpness off with some steel wool.

That should be able to sneak in under the cap, and you can either 'roll' it around a stationary cap, or "bow" it along the edge of a slowly rotating cap.

What happens is that the plastics aren't totally stable over a long time period, and they weaksn and become soft, brittle and crumbly.

Something in the dyes seems to exacerbate this in SSL green knob caps and Neve light blue knob caps...

I noticed that on my Sony mxp3k knobs.  Thanks for the advice.  This sounds perfect.
