Spindle Disassembly

I use a punch as said and or an end cutter. can get a better grip with an end cutter verses a side cutter.
 
Another trick you can try, if you have room clamp a small vice onto the key. I have often found if you get a really good grip on the key with a vice you can get them out without damage to either key or shaft.


Hello, my name is Brian and I'm a toolaholic!
 
No you can't punch it out from the inside of the shaft. I believe its a 12x24 lathe. Not sure though I'm pretty new at machining and not sure how to measure how big the lathe is. thanks to every one who has responded I will try a few different methods.
 
On a Commercial, the two choices are 24" or 36". Measure the length of either way. If 42", then it's a 12x24. If 54", then 12x36.
 
I'm surprised none of you have suggested a small brass drift 1/2 " x 6 inch long , set at the rear end of the key then smartly tapped down to raise the front , then use the drift to lift the raised end out the key way by laying it along the shaft and again tapping it smartly . That way you rarely ever get any damage to the key or the keyway . Do dress the drift up to remove any bur or mushroom on the head face before you start .

There should be a slight brass drift mark left on the key ....use that as a reference point so you put the key back in the same orientation just in case it has a slight deformation from its original shape .
 
On larger keys I have drilled a hole through the key to the base then tapped it as deep as possible, taking a machine bolt turn down enough of the end so that it won't bind the bottom of the thread the wind the screw in which will jack out the key. Note can't be used on smaller keys.
 
If you have access to a welder, you could weld a stud on the woodruff key and then pull it out with a slide hammer. It's a good way to do it if you can, but I realize a lot of shops won't have that capability. I've also clamped a set of vise grips to them and then used a hammer and punch on the nose of the vise grips to drive it out. It's a bit awkward and vise grips don't lend themselves well to the task. Perhaps someone should come up with some vise grips that have a good place for the punch to rest? Good luck.
 
I use an old Drum Brake adjustment tool to remove them when they are stuck.

Bill,

What does your drum brake tool look like? The two tools that I still have that I associate with drum brakes are scissors-type pull-off spring stretchers, The other end of one of the handles is machined but for pushing and turning the keyed washer on the compression spring loaded shoe retainer that some drum brake systems had.
