Default Removing difficult knobs

At my last job before retirement, my staff included four luthiers. Some of the instruments they worked on were very expensive, and whilst removing tight knobs, there must be no risk of surface damage.


I bought them one of these each after seeing it demonstrated at a show; they very quickly paid for themselves hundreds of times over.

I think the link you give has been highjacked! I just get a promotion webpage for Stewmac "membership" with no obvious way beyond it... Pity - sounds a useful tool.

The site works for me with a big advert for shipping that goes if you click outside it.
The puller looks like it is asking for a home brew copy at $68.

Default Re: Removing difficult knobs

I wanted to remove the knob from a guitar a few weeks back and tried to pull it off using a duster - just looped it under the knob and pulled up. It wouldn't move at all using my fingers.

The knob came off along with the shaft of the pot!

The funny thing is that I used a pair of pliers to remove the shaft from the knob and expected a proper struggle, but it just slipped out. Weird.

A bit cheaper initially at 7:30, but when you factor in VAT and shipping, not that different a cost, perhaps:

Yon device looks nice but I use two old teaspoons, card or similar can be used to protect any surface but the round profile of spoons does no damage. BTW that ad has tracking on it.
