Double Bass Removing threaded post from bridge foot.

[41 Hz]

I'm looking for advice and/or ideas around how to remove a threaded post from a bridge foot. I have an adjustable bridge that has 2 piece adjusters on it. There is an M8 threaded aluminium post embedded in the bridge foot. I am unable to pull it out or turn it. There is also a small steel pin, 1mm diameter or less in the side of the bridge foot. I'm assuming that this pin is what is preventing me from removing the post. My question is how do I remove this post from the bridge foot without destroying anything?
I've tried gluing a pin onto the steel pin in an effort to pull it out. The end of the pin is angled so not enough surface to grip. The end result of this is installing a Yamahiko pickup in there. If I get the post out and the foot isn't threaded then I've got other issues!
Thanks for your time.

Gently remove wood from the North side of the pin, and from the South side of the pin...(above and below the pin in your diagram), with an Exacto Knife, (or small chisel) - just enough to expose the tip, and then grip the tip of the pin with a pair of small needle-nose pliers. (Try slightly twisting the pin, at first, to break it "free" it from its hole in the threaded shaft. Then pull it towards you.)
That's what I would try and do.
You can repair the small hole, and "chisel divots", with some wood filler to coverup your crime.
Good Luck.

I was thinking small drill bits, North and South. I have variety packs from Ace Hardware.

Yeah...good alternative and cleaner!
We think alike - Sorry...

In case anyone’s interested.
I use them with a variable speed Dremel tool, with a fine chuck.

I don't know if they are available in a small enough size, but there is such a thing as a core drill bit, which is a hollow drill bit that drills around a core of material. If you can find one just slightly larger than the pin, you could literally drill the pin out in a core, then plug the hole by gluing in a thin hardwood dowel. In reading just now they are available in very small sizes.
