I've a set of cheap end cutters, the metal being similar consistently to Swiss Cheese, and as said, cheap and poor quality is beneficial to this application.
I've taken a tip from Steve in the past and as Nick says, to make sure the pin goes back into it's original hole.
I've a small bit of 2"x1" batten drilled with holes, and rough diagram of a box on the wood.
This way I make sure the pin goes back in its' original hole.

I think I'm starting to get most of the notes in roughly the right order...... sometimes!

Q's tip is a good one. I use a bit of polystyrene from a pizza packaging to stick the pins into. One pizza has yielded several years worth of pin holders!

Hohner bellows pins are usually of uniform diameter, so it's less crucial. But the brass bellows pins on Italian instruments can be of different diameters, even on the same instrument. The difference may be minimal and not easily detected by eye, which is why it is important to ensure the pins go back into their correct holes.

Thanks all...I do have a pair of end cutters...off to see if I can find a drill to drill said hole...

Lester...followed your link...sadly only available as an "add on" item with £20's worth of other stuff which, obviously, I discovered after ordering more than £20 worth of other stuff...c'est la vie say the old folk... :|glug

My wooden bellows pin "keeps".

My normal pin puller is a miniature end-nipper with an aperture filed into the jaws, but I also have a set of pliers with the serrations filed off and replaced with thick rubber padding (cycle inner tube) for those occasions when I need to get hold of the pin head, either to draw it completely or just to lift it slightly to make space for the other tool.

Don't know if this helps £3.10 and allegedly free delivery...

Mine are similar.

Ta...I'll try drilling a hole first...

If your drill or file will not touch the edge you can draw the hardness with a relatively small gas torch Baz probably worth pulling off plastic handle covers first though - alternatively small diamond coated rotary burrs or needle files are cheap enough these days - just don't expect lifetime service from them.

I see the need to lift as vertically as possibly, but I use this tool. I put tape around the fulcrum point to save any damage to the wood. I ease the pin out, lifting bit by bit until I can use my fingers.
(I am happy to accept any criticism here)

Well I feel that would still crush the wood beside the pin and leave a dent. If I had t use it, I'd use a piece of flat plastic or some such, to spread the pressure at least.  Don't know about celluloid covered boxes, but I wouldn't use it on any of my varnished wood boxes.

I wouldn't use one of those either.  It does give you the advantage of a more controlled pull, but the pull is in an arc rather than a straight line so there is a tendency to pull the pin against the side of the hole which will enlarge the hole.

Particularly if a pin has developed some rust, 'tis my view that rotating it first to break the grip is less likely to cause damage to the surface of the wood than just pulling lengthwise.

That's when the padded pliers come in handy. Mine are "parallel action" Maun, so they don't need much pressure to fang on tight to the pin (as we say in Suffolk).

If you do have to use one of those hook things, then I would place something like a credit card or large piece of fairy liquid type plastic bottle to spread the load. A piece of tape won’t do.

You don't 'have to use one of those hook things' pliers are easily available and the correct tool

Regarding the lever thing. Thank you all for your remarks. There's lot of control there of course but all the pressure is transferred to my (Castagnari...) wood. I have used a guitar pick in the past to spread the weight. I do get the nagging feeling the pin is being pulled up in an arc rather than straight out, although I do tend to pull the tool back in steps as the pin rises to alleviate that thought a little. There has been no perceivable damage to date (many taking aparts have gone on) but I will now in any case be looking at a correct tool and fashioning it to suit.
Thanks all.
