There's a bit of a back story to this.
Yesterday afternoon, it dawned on me that parts of my workshop have become something of a shambles -- too much stuff stashed away here and there that's of no real use to me, that's just cluttering up the place. I decided that it's high time for an unshambling. As for where to start, 'anywhere' seemed about right.
I started in on the bottom shelf of my wood lathe's stand, and came across this marvel of human ingenuity.
It's a flailing paint stripper that's due for retirement.
It did work, more-or-less, but it tended to litter the place with broken-off flails. It has few flails left -- there's really no point in hanging onto it. I'd like to salvage the 1/4" spindle, though, and that's where my hydraulic press comes in. (I could just hammer out the spindle with a pin punch, I suppose, but the press is way more fun.)
What I have in mind is a method of fitting a 6mm diameter 'nose' to the press' ram, to bear down on the spindle to press it out. Here goes.

Here's the setup, ready to go. (The lighting I was using made the camera produce some odd colouration effects -- the press is actually entirely red.)
That ram-end adapter is a 1 1/2" length of 1 11/32" diameter hardwood dowel. I bored it 1" diameter, 1" deep, and cut two slots in that bore's walls. Then, drilling through 15/64" gave me a light interference fit for a length of 6mm diameter steel rod. We'll see how this goes.

That worked nicely.
I can easily punch that spindle the rest of the way out, now that it's broken loose.
I can foresee variations on this method being useful again and again in future.

Addendum -- THURSDAY, JUNE 20, 2013
It was brought to my attention today that I did a poor job here of showing what it was, exactly, that I was salvaging. Quite so. Here's a view of what I was after with this endeavour.
It's an almost 3" length of hard, 1/4" diameter steel rod, with a knurl at one end.
To an amateur machinist, such things are invaluable -- they do not go into the landfill.
