Help with fork
 

What tool is needed to complete the removal? I'm doing a fork swap already removed one fork, now I'm unsure how to remove this other one any advice?

That (the Star Fangled Nut) is never coming out in a re-usable form, it's designed to be that way.

They are super cheap to buy a new one, you can go to your LBS for this/if your fitting a a new (threadless) headset, one will be included with this.

is the old for trashed/bent? will it be going to the recyclers? if so, you CAN reuse that star nut! simply cut the steerer tube BELOW the star nut, then drive it out of the tubing.... i install the star nuts by using a socket that is smaller than the steerer tube, and a socket extension, then make sure the socket/extension is in line with the tube. and drive it down into the new fork to a depth similar to the previous installed depth. DONE

or, do like the previous post says, and go get another star nut.

where i live, the nearest supply of new star nuts is either my stock, or an hour's drive, during daytime traffic, so re-using is a better option when i don't have a new one here.

There's a wedge shaped spacer where the fork enters the head tube that is all that's keeping your fork from falling out the bottom. Put a piece of wood atop the steer tube and hit it with a hammer. The fork will slide down far enough to release the wedge.

Star nut plugs are a one way deal. You can't remove them intact because they are retained by their domed shape which makes them bite harder when there's upward force.

So, consider them a permanent part of the fork, and buy a new one for the new fork. Or if you have to remove a damaged star nut to reuse the fork, you can push it deeper, and put a new one in it's place, or drill out the core, then turn the discs on their edges to pull them out.

Thanks fo your help. Neither fork are damaged I wanted to upgrade this cheaper aluminum (or steel) fork for a an old carbon one it seems​ like more work than I thought and is already a major hassle I'm not even sure the carbon one is much better since it's from the early 2000s so I'm going to leave them on their current bikes now I have to put the carbon one back on and hope i don't mess it up

That then brings up the issue of what steerer the carbon fork has, if it's metal (normally alu), then a new SFN is fine, if it's full carbon, you need to use an expander bung, as you can't use SFN's in carbon steerer tubes.
