Removing stuck cones from Formula track hub axle

This might seem slightly noob but can someone tell me how to remove a stuck cone on one side of a Formula track hub axle? When I try and remove it the cone on the other side comes off. Is there some trick I'm not seeing? (and I'd rather not pop the axle because the bearings are fine). TIA

Mind telling us why you are trying to remove it ? If you are just trying to service the bearings, there is no need to remove both cones in order to remove the axle and bearings for cleaning. Do you have cone wrenches ?

I'm with TT. I tend to remove the cone on one side and slide the axle right out. This way, I don't have to reposition the cone on that side, just adjust the cone I removed.

I was cleaning the wheel/hub/cones/nuts and regreasing the threads on the axle and for continuity's sake, figured I'd do everything. If you pop the axle out, doesn't that ruin the bearing? Yes, have cone wrenches.

This is all pointless, unless you remove the ball bearings to clean them along with the cup races that are pressed into the hub. You also need to pry out the dust covers to get the bearings out and clean the cups. You then need to apply fresh new grease to the cups and place the bearings in them, reinstall the dust covers, then slip in axle, install the other cone, adjust and tighten locknut. And, no, you do not ruin anything by removing the axle. Just be sure not to lose the bearings when they fall out.

I'm assuming you have loose ball bearings. If you have sealed cartridge bearings, then they do not need cleaning or adjustment.

You could use the park tool axle vise: Park Tool Co. AV-1 : Axle Vise : Hub & Axles
But like others said, just pull the axle out when you remove one of the cone nuts. Don't forget to have something to catch the loose bearings.

Let me rephrase. I'm surprised that BB's conduct electromagnetic radiation sufficiently to become polarised and be attracted by magnets.

Why? They're made of steel.

Most stainless steel isn't effected by magnets. I guess I wasn't expecting them to be ferrous. I'm not completely blown away; it just wasn't what I was expecting.

I guess all the stainless steel tools, cogs, etc I have at the shop are weird.

Actually, the best part is the sneaky commercial for cereal. Did you know that butter is one of the important ingredients in a healthy diet ?

Why all this nonsense about magnetic bowls and steel ball bearings? What's wrong with letting the balls drop down in amongst all them wood shavings from where you were building the boat last week like all real mechanics do? Not professional mechanics, their view on things is weirded by having to make money from mucking about with bikes, but us amateurs who can afford the time and frustration to really enjoy this wonderful hobby ...

oh who the fook am I fooling, I'm just annoyed I'd never heard of magnetic bowls
